❷ 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.
 

❸ Quality
Designed in compliance with guidelines like IGC 11/82 norm
 

❹ Features

• CRYOSTAR composite mechanical seal (4 timeslonger life time than carbon seals) 

 • for LCO2 application : special CRYOSTAR high pressure mechanical seal
 • for long life application : CRYOSTAR gas seal

• Front opening of housing: for an easier maintenance
• Designed to give a reliable and safe operation in all circumstances, particularly for oxygen operations
• Reduced dimensions/weight
• Pump speed can be adjusted through the variable speed motor (driven by a Variable Frequency Drive)
• Helical inducer allowing low required NPSH

Permacold barrier consisting of: 

• Volute separated from the electrical motor by an open intermediate piece with 4 hollow arms. This intermediate piece only presents 4 contacts points for low thermal conductivity.
• Hollow shaft reducing the thermal conductivity to minimum.
• Thick insulation plate providing low thermal conductivity
