Viking Pumps Specialize in:

The Workhorse of Countless Manufacturing Processes

The internal gear pumping principle was invented by Jens Nielsen, one of the founders of Viking Pump. It uses two rotating gears which un-mesh at the suction side of the pump to create a vacuum which pulls fluid into the pump. The spaces between the gear teeth transport the fluid on either side of a crescent to the discharge side, and then the gears re-mesh to discharge the fluid.

The Ultimate Solution for High Pressure Pumping

The external gear pumping principle uses two rotating gears which unmesh at the suction side of the pump to create a vacuum which pulls fluid into the pump. The spaces between the gear teeth transport the fluid along the outer perimeter of the housing to the discharge side, and then the gears re-mesh at the center to discharge the fluid. The gears are supported by bearings on both sides, which allows high discharge pressure capabilities.

Compact and Powerful Pumping Technology

Vane pumps are used for liquid transfer applications from chemicals to liquefied gases. Vanes extend from slots in the rotor, sweeping liquid through a cam-shaped cavity. The vanes provide very low slip and high volumetric efficiency.

Positive Displacement Pump Applications and Benefits

Viking Positive Displacement Pump

Many manufacturers—including those in the food and beverage, personal care, cosmetics, dairy or meat processing industries—benefit from a positive displacement pump. These pumps maintain a constant volume and positively displace any liquid—such as juice, fats, oil, gelatin, mayonnaise, syrup, creams, milk products, automobile paint and polymers—from a fixed-volume container.

Definition of Positive Displacement Pumps

We like The Engineering Toolbox’s definition: “Positive Displacement Pumps use an expanding cavity on the suction side and a decreasing cavity on the discharge side. Liquid flows into the pump as the cavity on the suction side expands, and the liquid flows out of the discharge as the cavity collapses. The volume is a constant given each cycle of operation.”

These pumps are divided into two main groups: rotary and reciprocating pumps.

Benefits of Positive Displacement Pumps

There are many benefits of positive displacement pumps for varying applications. Below we outline the main reasons many operations choose to use them. For more information, we recommend taking the Hydraulic Institute‘s new Positive Displacement (PD) Pumps: Fundamentals, Design and Applications e-Learning course.

  • PD pumps are sometimes called constant-volume pumps because they maintain a constant speed and flow. Even if the system pressure varies, the flow remains constant.
  • PD pumps can handle a variety of fluid types: high, low and variable viscosity; shear sensitive fluids; solids; and liquids with a high percentage of air or gas entrainment.
  • Their capacity is not affected by the operation pressure.
  • They are excellent for applications with flows below 100-gpm and above 100-psi.
  • They can be 10 to 40 points more efficient than centrifugal pumps when handling viscous fluids.
  • PD pumps are able to self-prime.
  • They can be designed as a sealless pump.

4 Signs of a Good Industrial Repair Service Center

industrial repair service center

Pumps and process equipment have helped manufacturers dramatically improve efficiency and increase their bottom lines. But when equipment fails or is not functioning properly, it has a negative impact on a manufacturer’s profit and reputation.

The best manufacturers have a trustworthy industrial-equipment partner who provides ongoing technical expertise, repair services, product support and custom fabrication. With professional service technicians and a comprehensive maintenance plan, manufacturers can prevent downtime and poor-quality end product—and save thousands of dollars.

When looking for an industrial repair service center, manufacturers should look for the following four characteristics:

#1 Expert Knowledge

Make certain the service center uses factory-trained service technicians who can repair and maintain your products, parts and equipment throughout the product lifetime. The company should offer factory-authorized warranties, repair estimates, field repairs and on-site maintenance work. In addition to equipment repair, the service provider should also perform contractual maintenance, laser alignment and equipment installation.

#2 Complete Equipment Diagnosis

It’s important that an industrial-equipment provider employs service technicians and field sales engineers who are trained to diagnose equipment problems and help resolve issues. This allows them to provide helpful and accurate technical support. Many service technicians offer Band-Aid solutions that don’t fix the root of the problem. A good service technician will carefully inspect each phase of the process to maximize quality control and fix the problem right the first time.

#3 Product Support

For a quick turnaround, a service provider should keep a large inventory of parts and equipment available to satisfy temperature, chemical compatibility, abrasion and longevity concerns. This eliminates the need to order parts and wait for shipping. When a manufacturer has genuine spare parts, its products continue to work at optimum efficiency, maintain performance, have a longer life and avoid expensive unplanned downtime. It’s even better if the repair shop offers custom parts manufacturing and can produce high-quality fabricated parts to meet customers’ requirements.

#4 Field Support

For complete peace of mind, a repair shop should provide field-service support for all equipment supplied for repair, including testing, calibration and system analysis. The technicians should be prepared with the latest equipment and training to correctly specify, install, troubleshoot and maintain your liquid or air process system.

At IPEG, our engineers and support staff are among the most experienced in the industry and provide helpful and accurate technical support—available to you 24/7. Increase up-time, reduce your maintenance cost and lead times, and gain total process control and maximum equipment performance.

Energy Savings beyond Electrical Components

By Kevin O’Brien

Many facilities today are constantly looking for ways to conserve energy and save money. Most have started replacing their light bulbs with more energy-efficient versions, and many are now putting electrical drives on their motors. However, numerous plants overlook the fact that their equipment is also mechanically wasting energy and money. Companies can save on energy costs by making their gear reducers, belt and chain drives and pneumatic equipment more mechanically efficient.

The Switch to a Helical Bevel Gear Reducer

Many smaller conveyors have worm gear reducers on them. These reducers are only 50 to 60 percent efficient. Many gear reducer manufacturers are going to a helical bevel style of gearing, which can be up to 90 percent efficient. In many cases, this allows the motor horsepower to be reduced, saving more money and energy.

One thing to consider, however, is that if you switch to the helical bevel gear reducer, the efficiency rating will go down if you increase the load and/or torque from that of the worm gear reducer. For example, if you had a worm gear reducer with a belt or chain drive on the output, and you switch to the helical bevel gear reducer driving the equipment directly, the gear reducer is now handling more torque and will not give you the efficiency ratings that are listed in catalogs. Even though the efficiency ratings may drop some, this is still a better solution than the worm gear reducer and will still provide energy savings.

The Case with Belt and Chain Drives

Belt and chain drives are another important factor in energy conservation. While chain drives are very efficient, most are not properly lubricated or maintained, causing increased failure and downtime. V-Belt drives can be inefficient when the belts or pulleys start to wear. Belt stretch also contributes to the loss of efficiency. When a belt stretches, the belt will slip in the pulley, wasting energy put out by the motor. Worn belts and pulleys will also produce slippage. If a belt or chain drive is a must for the application, a synchronous belt is a good and efficient solution. These belts can be over 90 percent efficient and require little maintenance.

Energy-Saving Solutions for Pneumatic Equipment

Pneumatically, many companies are bombarded with offers to do leak surveys to check for leaks in their pneumatic system. This is a very important first step, but other things should be considered as well. First, look at the size of the valves being used. If a valve was undersized to save money, it puts more strain on the compressor to provide the desired air pressure. If the valve was oversized, there could be too much air being delivered to the system. Either way, the compressor is working harder than needed.

Secondly, check the actuators. There are many double-acting actuators out in the field, meaning air engages and disengages the actuator. Many times the amount of air used to engage the actuator under load is the same as the amount of air used to retract the actuator. In many cases, this much air is not required to disengage the actuator. A solution would be to identity how much air is required to retract the actuator, and set it accordingly. A spring return actuator may be another solution. Air will engage the actuator and a spring will cause the actuator to disengage, cutting the amount of air usage in half for that actuator.

There are many great ways to cut energy use down electrically—especially with motors and drives. But if the mechanical components downstream are not efficient, there could still be a large amount of energy loss. When looking for ways to reduce energy, look at both the electrical and mechanical operations to gain as much of an advantage as possible.

Ask the mechanical experts at IPEG how your operation can reduce energy costs.

Improve Energy Efficiency with VFD Technology

VFD Technology

We turn off the lights when we leave the room. We turn down the A/C when we go on vacation. We turn off the water faucet when we’re not using it. So why are many companies running their pumps at full speed when it’s not needed?

Variable Frequency Drives

Variable frequency drives (VFD) reduce the total energy cost and life cycle cost (LCC) of an industrial pump, fan or compressor. The load profile for any industrial motor varies depending on multiple factors such as weather conditions and facility usage. VFDs are often a good choice for motors that don’t need to constantly run at 100%. They are able to monitor demand and change the motor output to match the load profile, ultimately making the motor more efficient and increasing energy savings. Also, VFDs help reduce the life cycle cost of a motor when it isn’t running at full speed at all times.

Read this article from Yaskawa to learn how to determine if a VFD motor is the right fit for your application. If you’re looking to speak to someone about your specific needs, contact IPEG or ask the IPEG experts.

Ball Valves: A Long-Term, Cost-Effective Solution

By Jim Newman

In the industrial world, valves are used to isolate or shut off systems. There are ball, gate, globe and plug valves, which are used for the majority of services. Other valve types, such as knife gate and pinch valves, have a much more specific application. For this discussion I will focus on the ball valve and why it is preferred.

Ball Valve Functionality

The ball valve is a simple device. It has a 90 degree operation and is easy to determine which position the valve is in: when the handle is cross line, the valve is closed; when the handle is in line, the valve is open. The 90 degree operation means there is no stem that rises and descends through rings of packing, which often drags whatever product is in the pipe up with the stem. The valve’s 90 degree operation allows for ease of automation with either electric or pneumatic actuators. Ball valves also have an inherent low pressure drop and offer bubble-tight shutoff. While primarily considered as on/off valves, ball valves can be used in throttling service by using coated balls and hard seats. Ball valves are also considered to be downstream sealing, as they utilize the system pressure to push the ball into the downstream seat to achieve their shutoff. There are exceptions to this, but generally this is the case.

Basic Ball Valve Designs

There are three basic ball valve designs:

  1. One piece body. This is usually referred to as a throw-away or non-repairable valve and requires a valve union or break point to remove the valve when the time comes.
  2. Two piece body. This is considered a repairable valve, but it still needs a pipe union to facilitate the repair.
  3. Three piece valve. This is considered a fully repairable valve without removing the valve from the system. Removing three of the four valve body bolts and loosening the fourth allows for the valve body to swing out the line and the internal components to be replaced. These internal components would be the seats and seals available in Teflon, reinforced Teflon, Buna, Viton, carbon-filled Teflon, along with other composite seats or sintered metal seats, depending on the service.

All of the valves above are available in brass, carbon steel, various grades of stainless steel and other alloys. They are available in threaded connections, welded ends, flanged and specialty connections.

Ball Valve Cautions

Ball valves, by design, can trap pressure in the ball cavity while in the closed position, so care should be taken while disassembling a ball valve. This would include cycling the valve from closed to open before servicing, and in the case of the three piece valve, the ball needs to be in the open position to swing the center out.

The ball valve may not be the least expensive option at the initial price, but after factoring in its life cycle, pressure drop, dependability and easy maintenance, it is a very cost-effective choice. Contact your IPEG representative to see if the ball valve is the best solution for your application.


Pump Repair: In-House Vs. Sending Out

By Bob Lang

In today’s economic climate, everyone is looking for ways to cut costs and/or improve efficiencies—whether it’s buying a car with better gas mileage to save on fuel spending or replacing leaky windows in your home to improve energy efficiency and save electricity. Call it being “green” if you like. It’s no different in today’s industrial plants. Companies want to run their equipment more efficiently and save money on energy costs. One great way to do this is to consider sending your rotating equipment to an outside vendor for pump repair.

Today’s industrial plants may run into many hurdles while repairing equipment in-house. These hurdles make it difficult to repair equipment to A-1 condition. Problems may include:

  1. Lack of Personnel. Cut backs on maintenance professionals don’t allow plants to devote as much time to equipment repair as they would like.
  2. Lack of Precision Tools. Many plants today lack the necessary tools needed to complete a precision repair.
  3. Lack of Time. This corresponds to number one above as well as inventory issues. When equipment goes down, many plants don’t have the time needed for precision repair.

Sending equipment for repair to an outside vendor allows companies to avoid most of the hurdles mentioned above. First and foremost, many vendors have an extensive inventory system while many plants don’t have the proper in-line spares or shelf spares needed for pump repairs. Outside repair shops also provide the following benefits for today’s industrial plant:

  1. Precision Maintenance. The time needed to make all necessary measurements and make sure all fit, form and function meets OEM requirements.
  2. OEM Information. OEM-approved repair shops have access to all necessary information needed to complete a precision repair.
  3. Impeller Balancing. Most plants these days do not have balance machines. Balancing an impeller is vital to the life of a repaired pump.
  4. Peace of Mind. Knowing, when you receive a pump back from a repair shot, it is in the best possible condition, ready to install, and ready for a long life.
  5. Quick Turnaround. Outside vendors can respond to any repair timetable necessary.
