LIQUID RING VACUUM PUMPS

Liquid ring vacuum pumps continue to provide the optimum solution for many rough vacuum applications in the chemical and allied process indus-tries. The general reliability, low maintenance requirements, low vibration and noise levels coupled with the unique capabilities when handling wet gases all contribute to the popularity of the pump.

Operating range Liquid ring pumps are suitable for continuous operation on vacuum appli-cations at any suction pressure down to 30 mbar A. Standard performance data is based upon 15 °C water as the seal liquid, lower pressures may be possible with alternative sealing liquid.

A wide range of capacities are offered from two basic pump configurations, single and two stages.

The single stage range is capable of operation at 30 mbar A where required, but is most suited to applications with continuous operation at inlet pressures from atmospheric down to 100 mbar A. The smallest pump in the range is a 25 m3h-1 close coupled model while the largest is 11000 m3h-1.

The two-stage range is most effective on applications with continuous operation below 100 mbar A and has models from 50 up to 5000 m3h-1.Detailed performance data is shown on the following pages.

Liquid ring vacuum pump range

Materials of constructionThe standard construction material is cast iron with either a spheroidal graphite or bronze impeller depending upon the series. One of the main features of the liquid ring pump is the availability of various alternative materials of construction. The main options are stainless steel, aluminum bronze, and duplex stainless steels. Some pump sizes, which are particu-larly suited to the pharmaceutical industry, are also available in hastelloy.

How it works

1 Suction 5 Sealing ring

2 Discharge 6 Direction of rotation

3 Discharge port 7 Suction port

4 Casting 8 Impeller

The impeller is mounted eccentrically to the axis of the pump casing, the liquid ring circulates concentrically within the axis of the casing. Process gases are drawn through the inlet port into the impeller cells where the gas is compressed and discharged through the discharge port. The seal liq-uid which forms the liquid ring is supplied at a pressure equal to the dis-charge pressure of the pump, which allows the pump to automatically make up the amount of liquid which is discharged through the discharge port, therefore removing the heat of compression from the pump.

APPLICATIONS

Some of the more common processes which utilize liquid ring technology are listed below.• Distillation• Filtration• Evaporation• Drying• Stripping• Solvent recovery• Deaeration

These processes are used in a wide range of industries and applications, which include:• Chemical processing• Food processing and packaging• Pharmaceutical production• Oil exploration and refining• Glass industry• Tobacco conditioning• Packaging• Electronics industry• Automobile components• Power generation• Waste collection• Building materials• Soil remediation

SystemsLiquid ring pumps are offered in a number of standard configurations, with a selection of seal liquid systems to suit the particular application and envi-ronment.

SLRP configuratorThe SLRP system utilizes 3D AutoCAD design software to produce a tai-lored liquid ring pump package constructed from pre-engineered modules. The main benefits being the instant availability of a customized quotation and package general arrangement drawing and reduced lead times.

The system offers a selection of pump material options along with a choice from three standard operating configurations to suit the process condi-tions.

Once-through This is the most basic configuration available, it comprises of a pump com-plete with electric motor and drive and base frame. A discharge separator is required at the pump discharge. It is used where an ample supply of seal liquid, which can be subsequently discharged to drain, is available. The liq-uid/gas mixture is discharged to drain through the discharge line.

Partial recirculationIn this case, the liquid/gas mixture is separated in the discharge separator. The recovered service liquid is then mixed with fresh seal fluid to maintain a constant temperature to the pump. The excess liquid, equivalent to the make-up supply, goes to drain. The minimum amount of fresh make-up fluid is used to ensure cavitation free operation at the required suction pressure.

Total recirculationTotal recirculation is used where it is desirable to minimize waste liquid from the pump. All of the liquid is re-circulated back into the pump via a heat exchanger, which removes the heat of compression and any latent heat of condensation from the seal liquid. The seal liquid can then be reused by the pump minimizing the effluent from the pump system. The system is of particular interest when the pump is operating on a solvent removal or drying process where process vapors are condensed within the pump, often the pump seal liquid can be the same as the condensed pro-cess vapors.

Hazardous areasThe SLRP packages and accessories are available certified for hazardous area operation:• European ATEX Ex II 2Gc, IIB T3• USA Explosion proof Class 1 Division 1 Group C & D• Packages suitable for operation in other zones such as ATEX Cat 1 are

available on request.

Non configured packagesPump sizes outside of those covered by the SLRP configurator are available on request, these customized packages are designed specifically in accor-dance with customer application requirements and specifications.

Complex systemsMore complex systems include special recirculation systems such as the Recovac package (see later) or combinations of liquid ring pumps with roots type mechanical boosters or air, gas or steam ejectors. These hybrid systems can extend the liquid ring pump based performance envelope sig-nificantly.

Recovac system

The Recovac System adds a highly efficient closed circuit heat exchanger system to the inherent chemical process pumping benefits of the liquid ring vacuum pump. The result is a highly effective vacuum pump package with in built emission cleaning/solvent recovery capability.

By combining the wide range of liquid ring pumps, ejectors and mechanical boosters capacities up to 30000 m3h-1 can be achieved with suction pres-sure down to 0.01 mbar A.

To make the most of the Recovac system a seal liquid which is compatible with the process should be selected, often this will be the same solvent that is being produced from the wet vacuum process. This enables conden-sation of process vapors in the liquid ring itself with further recovery being achieved in the falling film heat exchanger. Additional cooling can be pro-vided for further reduction in the discharge temperature.

SHR SERIES LIQUID RING VACUUM PUMPS

The SHR Series covers capacities from 500 to 5000 m3h-1 with suction pressures down to 30 mbar A. The pump design incorporates many of the requirements of API 681 as standard and can be modified to meet cus-tomer specific specifications. Specialized seal arrangements, design pres-sures, inspection procedures, documentation and quality assurance needs can be accommodated.

Generally these models will form an integral part of a fully engineered pro-cess vacuum system.

Pump performance

Performance based upon dry air at 20°C and seal water temperature of 15°C, atmospheric pressure of

1013 mbar A. Subject to a 10% tolerance.
