Perfectly Replace The Kinney Water-ring Vacuum Pump

Our vacuum pump(KLRC Two-Stage Water-ring Vacuum Pump) can perfectly replace the Kinney water-ring vacuum pump, and the following is the corresponding model of the Kinney.

What is a Two-stage Water Ring Vacuum Pump?

The two-stage water ring vacuum pump uses the gas discharged from the first stage exhaust port to be inhaled by the second stage suction port, and then compressed and discharged by the second stage. The second stage is to reduce the exhaust pressure of the first stage, so as to improve the suction limit vacuum of the first stage. This is completely different from the ordinary water ring vacuum pump. Then the bearing, bearing bracket, and cover are all made of stainless steel and aluminum bronze.

The vacuum pump has an anti-corrosion effect on extracting some acidic or corrosive gases. It is widely used in resin production enterprises and chemical enterprises. Two-stage water ring vacuum pump is mainly used to pump and transport air and other gases, especially for gases containing a large amount of water vapor and other corrosive gases, such as vacuum distillation and drying in the chemical industry, vacuum dehydration in the light textile industry and paper industry. When it is used as the front pump of the supercharger, the application range of the supercharger can be greatly improved.

Two-stage Water Ring Vacuum Pump Working Principle

In order to generate a vacuum in the two-stage liquid ring vacuum pump, the multi-blade impeller on the shaft is eccentrically positioned in the cylindrical shell. Which is partially filled with sealing fluid When the shaft rotates, the centrifugal force generated by the rotating impeller generates a liquid ring. This force keeps the liquid ring on the inner wall of the pump chamber. Because the impeller is eccentric in the pump chamber, the depth of the blade entering the liquid ring decreases and increases with the rotation of the impeller.

This increases the volume of the battery at the inlet end, creating a vacuum. On the discharge side, as the blade further enters the liquid ring, the volume of the impeller unit decreases. This will increase the pressure until it is discharged through the discharge port. The continuous flow of fresh sealing liquid is supplied to the pump through the sealing liquid inlet. The liquid will not be discharged from the first stage to the atmosphere. Instead, the first-stage discharge enters the second stage through the manifold and through the discharge port in the intermediate plate between the first and second-stage impellers.

Two-stage Water Ring Vacuum Pump Characteristics

The double-stage water ring vacuum pump has high maximum pressure. Unlike single-stage water ring vacuum pumps, two-stage water ring pumps offer better efficiency. They are more effective at higher vacuum levels and can also be used in chemical and pharmaceutical installations. These products are available for a wide range of applications.
Its compact design, reduced power consumption, and variable discharge port make it ideal for continuous operation. Designed for pharmaceutical and chemical installations, the two-stage water ring vacuum pump has lower exhaust pressure and greater efficiency than its single-stage counterpart. So, if you need a deep vacuum, this is a great solution. These machines have the highest level of efficiency and are ideal for most industrial environments.

KLRC Two-Stage Water-ring Vacuum Pump Applications

The two-stage water ring vacuum pump is mainly used to pump and transport air and other gases, especially for gases containing a large amount of water vapor and other corrosive gases, such as vacuum distillation, drying in the chemical industry, vacuum dehydration in the light textile industry and paper industry. When it is used as the front pump of the supercharger, it can greatly improve the scope of use of the supercharger.
Some of the industries where a water ring vacuum pump is ideally a good option are as below:

Pharmaceutical and Chemical industry: In this industry, water ring vacuum pumps are used as compressors and vacuum pumps. It is used for various processes such as Filling, Filtration, Cooling, Crystallizing, Distillation, Deaeration of caustic solutions, Solvent Recovery, and many more. Automobile Industry: In this industry, it is used for Engine testing, Carburettor testing, vacuum filling of power steering and brake fluid. Petroleum Industry: Vacuum priming, vacuum cleaning, and filling of barrels, filtration, vapor recovery, etc. Pulp and Paper Industry: Paper coating and dehydration of paper webs Food Industry: Bottling industry, sausage production, sweet production, degasification of mineral water, powder conveying, etc. Mining industry: Vacuum filtration, gas boosting, drawing off of pit gas Textile industry: Hydro extractor Plastic Industry: Extrusion degasification, vacuum calibration, drawing off and compressing vinyl chloride gas Energy production: Duration, Fly ash conveying, and evacuation of steam turbine condensers.

Difference Between Water Ring and Oil Ring Vacuum Pump

the working principle

The water ring vacuum pump consists of a cylindrical housing partially filled with sealing liquid to create a vacuum. The vacuum generation is done through a rotating multi-blade impeller mounted on a shaft positioned eccentrically within the housing. The rotation of the impeller creates a centrifugal force, and a liquid ring is created. This liquid ring creates the vacuum needed for an operation.

Dry screw vacuum pumps generate vacuum through the rotation of two screw rotors arranged parallel to each other, rotating in the opposite direction. The rotor’s movement decreases the volume of the trapped gas and results in the compression of the gas, moving it out through the exhaust. No lubrication is required in the compression chamber as the rotors do not contact each other during the compression process. As a result, this is referred to as dry technology.

discharge temperature

The inherent design of a water ring pump has the benefit of allowing using a variety of liquids as sealants, including solvents, oil, water, or other compatible fluids. As the liquid is in contact with the compressed gas/vapors in the process, the gas compression is considered isothermal. The final discharge temperatures at the outlet are controlled between 45 and 150°F. Hence the liquid ring vacuum pump offers great flexibility as different gases can be either condensed or passed through it.

Due to the constant-pitch design or progressive pitch design of dry screw vacuum pumps, the gas/vapor is transported at constant volume to the discharge port. The compression process is considered adiabatic, with discharge temperatures as high as 450°F. Such high temperatures can cause safety concerns with this pump technology.

operation conditions

The water ring vacuum pump can take the dirtiest application and have a high tolerance for harsh environments, violent saturated air, or vapor loads. Since the gas compression process is isothermal, the pump is suitable for pumping flammable, explosive, and toxic gases.

The dry screw vacuum pump is not suitable for pumping gases contaminated with oil, dust, or water vapor. Applied to a relatively dry clean gas stream only.

operation and maintenance cost

Water ring vacuum pumps have only one moving part – impeller, and there is no metal-to-metal contact between the rotating parts and the casing. With these design characteristics, liquid ring pumps are easy to maintain, and there is no need to replace the accessories for 2-3 years.
Dry screw vacuum pumps require the replacement of lubricants and require expensive inlet filtration systems. Hence the complete repair and maintenance of dry screw pumps incur high costs.

Water Ring Vacuum Pump	Dry Screw Vacuum Pump

Thus, we conclude that, from the above differences between the water ring vacuum pump and dry screw vacuum pump, you will now be able to decide the right pump for your industrial application. Picking the right vacuum pump will ensure you a smooth operation with a high return on your investments.
