Description:

1. All electrical components have an anti-explosion configuration.
2. The pump head has a vacuum jacket that minimizes cold loss.
3. Piston seals are made of unique material with a life expectancy of 4000 h.
4. With pressure pulsation on the outlet, the load is stable.
5. The transmission box is equipped with a stable and self-lubricating operation.
6. Cryogenic centrifugal pumps are capable of pumping large amounts of liquefied industrial gases.
The unit is equipped with a temperature monitor for the transmission case and an interlocking control system to ensure safety.

Optional Configuration:
1. Fixed speed motor/frequency conversion motor
2. Safety valve/Cryogenic interlocking device for overpressure
3. Pressurized interlocking device for outlet liquid

Features:
1. Compact structure, simple design
2. Worm wheel, impeller and rotor are made of high-strength alloy bronze to ensure safety in liquid gas.
3. Cavitation-resistant mechanical seal or labyrinth, easy installation and removal, long life.
4. High-strength hollow stainless steel shaft
5. Impeller with low dynamic unbalance
6. A motor with a frequency converter makes the pump applied more widely
7. Flexible connection between the liquid inlet and outlet, a filter for the liquid inlet, and stable operation with a slight vibration.
8. These pumps operate on the principle of centrifugal force.
