❶ Test procedure

Each pump manufactured by CRYOSTAR is mechanically and cryogenically tested prior to shipment in our state-of-the-art testing facility to ensure that performance meets customer specification. The precision of measuring devices provides essential results: differential head, flow rate, seal gas consumption, pump efficiency, NPSH, noise and vibration levels - all documented and submitted to the customer.

❷ Quality

Designed in compliance with guidelines like IGC 11/82 norm

❸ Featuers

1 .  Front opening of housing: easy and reliable replacement of mechanical seal without the need for re-adjustment of the run-out.

2 .  CRYOSTAR composite mechanical seal (4 times longer life time than carbon seals)

-> for CO2 application: special CRYOSTAR high pressure mechanical seal

-> for a long life application : CRYOSTAR gas seal 

3 .  High hydraulic efficiency closed impeller.

4 .  Helical inducer allowing low required NPSH. 

5 .  Splash lubricated gearbox with oxygen compatible oil.  thích.

6 .  Helicoidal gearwheels for low noise level. 

7 .  Pump support with 3 bearings: 2 for radial thrust and 1 for radial and axial thrust

Permacold barrier consisting of: 

8 .  4 hollow arms open intermediate piece between the volute and the motor. 

9 . Hollow shaft reducing thermal conductivity to a minimum.

10 . Thick insulation plate providing low thermal conductivity
