Product Overview

A liquid ring compressor for large gas volumes at medium and low discharge pressure. With only one rotating part and reworked wet-end profiles for long life, it handles flammable and corrosive process gases with very little maintenance.

Simple and robust

Axial suction and discharge, a single rotor and no internal metal contact mean high availability and low maintenance cost.

Materials for aggressive gases

Wetted parts are available from standard carbon steel and cast iron to stainless steels, duplex, titanium and Hastelloy.

Process references

Rubber tail-gas compression, styrene, VAC, acetylene in BDO plants, ash-sluicing water treatment, solvent recovery, PSA units, benzol-ketone dewaxing, polyether, wax-oil hydrogenation, PTA vacuum filtration, methanol and glycol production.

Frequently asked questions

What discharge pressure is possible?

Up to 0.25 MPa(g). For higher pressures see the high-pressure liquid ring compressor or the tandem package.

Which materials are available?

Carbon steel/cast iron, SS304, 304L, 316L, duplex, titanium and Hastelloy.

What information do you need for a quotation?

Flow rate, head or vacuum level, the liquid or gas and its temperature, required materials, motor voltage and frequency, and any standard or ATEX zone. A data sheet or the nameplate of an existing pump is ideal.
