Cryogenic liquid pumps

Repair, maintenance amd commissioning of cryogenic pumps of all international brands

Filling applications

The piston pumps with the high standard of gas filling stations: The advantages can be highlighted as follows: high mechanical strength, long life, simplicity of assembly, high reliability, easy maintenance.
The current range is the result of a long innovative evolution which allows it to meet most requirements in the field of flow (up to 700 L\min in triplex version) or discharge pressure (up to 1'000 bar), for all liquid gases.

LNG Pump

THE VSMP PUMPS

The Vertical Sealless Motor Pumps series of sealless single or multistage centrifugal pumps is mainly for use with combustion gases like methane, high suction pressure gases like Carbon dioxyde, expensive gases like Argon, where all risks of gas leakage of the process gas contamination are eliminated.

 

The main feature of these pumps are:

Maximum level of safety with LNG (gas tight)
Flowrate up to 2'500 L/min
Single or multistage: differential head up to 1'000 m
Available for all cryogenic gases including LNG
