Viking pump buyers no longer have to rely on mechanical seals or packing for their pumps. Packing breaks down and needs to be replaced. Mechanical seals break down causing leaks. Both packing and mechanical seals require contact with the rotating shaft – which increases wear and tear on the shaft… and causes energy to be wasted in the form of friction.

Introducing O-Pro Seal Technology

Viking has developed the O-pro seals to create a robust seal and lubrication chamber all in one. The O‐Pro™ Barrier seal functions as both a seal and bracket bushing.

New Viking pumps can be purchased with O-Pro seals and Viking pumps already in service can be upgraded with an O-Pro seal kit for a simple field retrofit. Available from Pye-Barker Engineered Solutions today.

How Does An O-Pro Barrier Seal Work ON New Pumps?

The O‐Pro™ Barrier seal replaces packing and/or mechanical seal by occupying the internal bracket cavity with a machined seal gland utilizing O‐rings to seal externally on the bracket and internally on the shaft. The area between the bracket, gland and shaft are then filled with a lubricating fluid. This combination of O‐rings and lubricating fluid provide a robust seal preventing process fluid from leaking out of the pump, as well as, a lubrication sleeve in which the shaft operates in creating a low wear environment, increasing pump life.

How Does An O-Pro Cartridge Seal Retrofit Onto Existing Pumps?

The O‐Pro™ Cartridge seal replaces packing and/or mechanical seal by sealing the bracket cavity with a machined seal gland that utilizes O‐rings to seal externally on the bracket and internally on the shaft. Internal seal cavity between the gland and shaft is filled with a lubricating fluid. The combination of O‐rings and lubricating fluid provide a robust seal keeping process fluid from leaking out of the pump. The design of the O‐Pro™ Cartridge seal allows for an easy retrofit while addressing the need for stainless‐steel seal construction.

Each different kind of pump possesses its own weaknesses and strengths. As a buyer, you might find it challenging to choose among the options that can be selected for the same type of application. Today we’re sharing information regarding Finish Thompson end suction pumps in GA.

An end-suction pump is the most fundamental type of centrifugal pump designed with a covering. The suction is on one end of the pump and the discharge is placed at the top, which is why it is was referred to as an end suction pump.

How End-Suction Pumps Work

Finish Thompson end suction pumps in GA usually contain a casing which has coil windings and an impeller. When the liquid passes through the fins and blades of the impeller, the velocity increases. The liquid then passes through the casing where its high velocity is converted into high pressure through a process of circulation.

End suction pumps can be propelled by:
• D.C. motor;
• Hydraulic motors;
• A.C. electric motors;
• Steam turbines;
• Air motors;
• Diesel and petrol engines.

End suction pumps may be frame-mounted or close-coupled, making them the best option for non-critical and intermittent and service applications.

Types of Finish Thompson End Suction Pumps in GA

Close-Coupled End Suction Pump: In these pumps, the motor shaft and the pump shaft are the same, and the motor bearings and pump bearings are the same. The impeller is attached directly to the one end of the motor shaft. These close coupled pumps require less space and are also cheaper than the frame-mounted option. Close-coupled design provides compact construction and space savings and. A permanent rigid alignment in these pumps eliminates the need for all other alignments, thereby prolonging bearing and seal life.

Frame Mounted End Suction Pump: This type of Finish Thompson end suction pump in GA has bearings and shafts that are independent of the motor. To transfer energy from the pump to the motor, a coupling is required. The frame-mounted category of end suction pump comes with a double volute design. The main features of this option are lower life-cycle costs and increased efficiency. The footed bearing frame delivers easy maintenance. The impellers are trimmed and balanced providing customization.

With a wide variety of centrifugal pump configurations available in the market today, it is vitally important to fully evaluate the strengths and weaknesses of each type of end suction pump when choosing a new pump for your industry to minimize the maintenance costs, particularly when you are involved with critical applications.

If you need a pump, blower, vacuum, air compressor, or a complete system - or would like to learn more about Finish Thompson end suction pumps in GA - we will specify a solution based on your needs and requirements. Call our office today to speak with one of our experts.

When it comes to chemical, petrochemical, gas and other industrial processes, reciprocating compressors play a chief role. These compressors are the most widely used and well-known compressors that involve positive displacement based on a specific set of reciprocating compressor parts in GA.

So, what are these reciprocating compressor parts and what do they do?

What Is A Reciprocating Compressor?
These are positive-displacement mechanisms that work on a reciprocating principle to be able to deliver gas at high pressures. The motion is supported within the device with the use of pistons. Reciprocating compressors can usually be separated into two types: Separable (high speed) and Integral (low speed). Within the natural gas industry, large reciprocating engines are utilized to generate low-pressure plants, move natural gas through the pipeline, and supply high-pressure gas for a good drilling.

Types Of Reciprocating Compressor Parts In GA

Reciprocating compressors are made up of numerous parts; below, we examine some of these parts.

Cylinders: The cylinders found in process industries are detachable from the frame, so they accommodate both suction and discharge valve plates. Small, higher-pressure cylinders are usually made from steel, while larger, low-pressure cylinders are created from cast iron.

Pistons: Often referred to as the heart of the reciprocating compressor, the pistons are made from low-weight materials such as aluminum to decrease rod load and shaking. They are responsible for the conversion of energy to the gas in the chamber from the crankcase.

Piston Rod: The piston rod is threaded through the piston and is responsible for transferring the reciprocating crosshead into the piston. They are usually manufactured from alloy steel.

Distance Piece: This detachable housing connects the frame and the cylinder. I can include multiple compartments and it can be open or closed, single, double, or extra-long. The purpose of these reciprocating compressor parts in GA is to separate the rod that enters the crankcase and gets lubrication from the cylinder that is in contact with the gas.

Rod Packing: Much like the piston rod, rod packing is important to prevent gas leakage as it passes through the crank closure and cylinder. Packing rings are located at the head of the rod packing assembly.

Crankshaft: Reciprocating compressors above 150 kW (200 hp) typically include crankshafts constructed from steel. Each crankshaft should have a changeable balance weight, but when over 800 rpm the crankshaft should be balanced dynamically

Bearings: The main rod and connecting bearings should be split-sleeved and steel-backed. Anti-friction bearings can only be used in components that are rated lower than 150 kW.

Connecting Rod: Similarly to crankshafts, connecting rods are used in compressors that are above 150 kW (200 hp). Also made from forged steel, it also has a drilled hole to allow the oil to pass.

Cross Head: This component is used to guide pistons into the cylinder bore, so it allows a longer strength and greater capacity with a heightened control of oil carryover.

Valves: Possibly one of the most essential reciprocating compressor parts in GA are the spring-located, gas-actuated, valves. In general, one of these three valve configurations is used: Plate Type, Poppet Type, or Ring Type.
Lubrication System: Both heavy-duty and medium compressors need force-type lubrication. The main components are the:

• pressure regulating valve;
• lube oil tank;
• main oil pump;
• dual oil filter;
• lube oil cooler;
• associated accessories.

Reciprocating compressors transport natural gas from the suction manifold and into the natural gas cylinder, which is also referred to as the compression cylinder.
An internal combustion engine powers this entire process.

When the compressor’s operating life increases, the rings packing systems will wear out, resulting in higher leaks. Therefore, high-quality components and expert installation are key to ensuring balance in this essential system.

A compressor boosts the pressure of a gas, reduces the bulk of it and expands its density without turning it into a liquid. Gardner Denver reciprocating compressors can do this in a number of ways.

A common factor between all compressors is that they all use some type of fuel, such as electricity or gasoline, to power the compression method they utilize. Also, because the compressor increases the pressure on the gas, it also elevates the temperature.

Components of a Gardner Denver Reciprocating Compressor

A reciprocating compressor utilizes pistons to compress air. The compressor has a comparable design to an internal combustion engine and it even looks similar. A central crankshaft drives anywhere from two to six pistons located inside cylinders. It is typically driven by an external motor that can be internal combustion or electric.

Compressing the Gas

As the piston recoils, gas is inserted from a valve located in the compressor. It is injected into the cylinders and is then compressed and discharged either to be used right away by an air-filled machine or stored in compressed air tanks for later use. The gas, however, must be stored or used directly from the compressor so it doesn’t lose its pressurization.

Gardner Denver reciprocating air compressors are widely viewed as being workhorse compressors because of their robust durability.

Industrial reciprocating compressors can operate in more severe-duty environments while offering lower initial costs. Because of their lower maintenance costs, they are great for sporadic duty operation. They operate efficiently at partial loads and save energy in no-load conditions, resulting in higher overall efficiency.

Types of Gardner Denver Reciprocating Compressors

Single acting: On this type, the piston works only in one direction. The other end of the piston is often open or free where no work is performed.

Double acting: As you can tell from its name, it uses both sides to compress the air. These type of compressors have two sets of intake/suction and exhaust/delivery valves on both sides of the piston.

In-line Compressors: Its name explains the design of the compressor. The cylinders are in a straight line when viewed from the top. They are most commonly used compressors where varying pressure is needed.

V-shaped compressors: These are air cooled compressors with parallel valves mounted on each cylinder head which are placed in a V-shape at a 90-degree angle from each other.

Recently, I took you through the workings of an internal gear pump. Today I’m going to guide you through the inner workings of an external gear pump.

How do They Work?

External gear pumps use two identical gears rotating against each other to drive fluid from the suction port to the discharge port. Each gear is supported by a shaft with bearings on both sides of the gear. Typically, all four bearings operate in the pumped liquid.

Because the gears are supported on both sides, external gear pumps are often used for high pressure applications. Usually, small external gear pumps operate at 1,750 or 3,450 rpm and larger versions operate at speeds up to 640 rpm.

The design of external gear pumps allows them to be made to closer tolerances than internal gear pumps. The pump is not very forgiving of particulate in the pumped liquid. Since there are clearances at both ends of the gears, there is no end clearance adjustment for wear. When an external gear pump wears, it must be rebuilt or replaced.

External gear pumps handle viscous and watery-type liquids. Thicker liquids require careful setting of the pump speed because gear teeth come out of mesh for a short time, and viscous liquids need more time to fill the spaces between the gear teeth than thinner liquids.

The pump does not perform well under critical suction conditions. Volatile liquids tend to vaporize locally as gear teeth spaces expand rapidly. When the viscosity of pumped liquids rises, torque requirements also rise, and pump shaft strength may not be adequate. We supply torque limit information when it is a factor and advise against external gear pumps for applications when the torque requirements to pump a given liquid are beyond the tolerances of a given pump.

What Do We Use Them For?

We see external gear pumps used to pump fuel oils and lube oils, chemical additives, on hydraulics and low volume transfer applications. It is also common to use an external gear pump for chemical mixing and blending.

I know that we’ve been hearing a lot about oil free air compressors of late. Some of you might be wondering about the hype. I believe they are worth the hype and they can represent incredible value to the right customer.

I suspect that as we move forward and the technology becomes more widespread, the costs will come down and we will see the broader market turn to oil free air.

So I’m going to share the ideal situation to consider an oil free air compressor.

Where I Would Look Long And Hard At Oil Free Air Compressors.

Gardner Denver Oil Free Air Compressors do deliver 100% oil free air. No conventional air compressor can offer that. Once oil is in your compressed air it’s impossible to get it 100% out. No scientist would make that claim and no company would guarantee that their filtration system can clean air from conventional air compressor so that you get 100% oil free air all the time.

It’s just a recipe for legal troubles.

You can make those claims with an oil free air compressor.

ISO-Class 0 air is air that is 100% completely oil free. The best you can get with a conventional compressor is .1 mg/m3 under ideal conditions. I’ll admit it can be good enough but it requires a filtration system.

You don’t need to invest in or maintain an oil removal/filtration system if you use an oil free compressor. There’s a savings and depending on the quality of air you need it can be a big one over the life of a compressor.

Then there is always the risk of a contamination ‘event’ and downstream damage. This can be either from oil in the compressed air contaminating your end product – e.g. pharmaceuticals or food and beverage applications or the oil could damage your equipment that runs on compressed air e.g. pumps and tools.

Where you are looking to replace your air compressors anyway and would like to eliminate the costs or the ‘risk of expense’ associated with maintenance and repairs or product damage, that’s where there could be a big payoff. Cleaning up a disaster could well cost you far more than the oil free compressor would have cost.

If you are looking for a new compressor, the team here at Pye-Barker can guide you through the process. Please call 404-363-6000 or drop us a line and we will explore a range of options based on your circumstances with you.
