Handles wet and dirty gas
Water acts as the liquid piston and sealing medium, so vapour, moisture and carryover are tolerated.
Product · Vacuum & Compression
Liquid ring vacuum pumps and compressors for demanding duty.
The GLRP vacuum pump and GLRC compressor series handle gas and vapour where dry machines struggle — wet, dirty, flammable or explosive service — with near-isothermal compression and energy-optimised hydraulics.

Overview
Wet, dirty and hazardous gas is exactly where these machines belong.
Glorinda compact / direct-coupled liquid ring vacuum pumps are designed for the suction of gas and vapour in industrial processes. They reach a suction pressure of 33 mbar (abs.), equal to 97% vacuum; when operating as a compressor the maximum pressure is 0.26 MPa (abs.). A cavitation protection pipe protects the system during long operation near the limit vacuum.
The energy-optimised series uses a conical suction and discharge port, giving a wider flow area and lower resistance than flat-port designs — allowing energy savings of up to 18% when pumping air and 28% when pumping saturated steam.
The GLRC liquid ring compressor series compresses gas up to 0.7 MPaG from a single-stage impeller. Because compression is close to isothermal, it reduces risk when handling flammable or explosive gases — a decisive advantage in flare, chlor-alkali and petrochemical service.
Products are developed under the Glorinda brand and manufactured by qualified OEM partners. Glorinda controls technical specification, branding and quality control.

Why this product
What it gives you
Safe on flammable gas
Near-isothermal compression keeps temperatures down when handling flammable or explosive gases.
Energy-optimised
Conical suction and discharge ports cut resistance — up to 18% saving on air, 28% on saturated steam.
Long service life
No metal-to-metal contact between rotor and casing; stainless steel impellers resist corrosion.
Cavitation protection
A cavitation protection port reduces noise and protects the pump during high-vacuum operation.
Explosion-proof options
“-E” models carry motors certified to dIIBT4 / dIICT4 for hazardous environments.

FAQ
What vacuum level can these pumps reach?
A suction pressure of 33 mbar (abs.), equal to 97% vacuum. A cavitation protection pipe is used when operating near the limit vacuum for long periods.
How much energy can the optimised series save?
The conical suction and discharge port design gives up to 18% energy saving when pumping air and up to 28% when pumping saturated steam, compared with flat-port designs.
Are explosion-proof versions available?
Yes. Models with the “-E” suffix are equipped with motors certified to explosion-proof class dIIBT4 / dIICT4 for flammable or hazardous environments.
Why choose liquid ring over dry vacuum?
Because water acts as the liquid piston and sealing medium, liquid ring machines tolerate wet, dirty and vapour-laden gas that would damage dry pumps — and near-isothermal compression makes them safer on flammable gases.
Can you supply non-standard materials?
Yes. The standard configuration uses SS304 wetted parts, and non-standard products can be produced to customer requirements.
