L-CNG High Pressure Pump

L-CNG High Pressure Pump
Medium: LNG
LNG Cryogenic Pump
LNG Cryogenic pump is used for pressurizing, vaporizing the liquid in the cryogenic tank and then filling into High-pressure steel cylinders or network, LNG dewar, LNG cryogenic trailer, LNG cylinders and LNG liquid tank.

Optional Configuration
Frequency converter
Explosion relief overpressure interlocking device
Safety valve, cryogenic shutoff valve
(liquid inlet, air return discharge)
Temperature interlocking device
Leakage detecting device

Function
This pump, with novel structure, good material, exquisite processing technology, stable performance, easy operating and maintenance, long service life.
Transmission mechanism is the crosshead structure, with long service life.
High vacuum jacketed cold end pump head, low cold loss and vaporizing capacity, short pre-cooling time, less liquid loss.
Built-in filter, practical and reliable.
Piston ring, guide ring and seal ring are made up of polymer composites with good abrasive resistance, with long service life.
Convenient operation, short starting-up time.
Operation of the pump may not lead to pressure increase of the tank, however, long time operation reduces pressure.
Explosion proof Motor is used, greater safety coefficient with flexible, convenient and safe operating.
Low power consumption, and operation with low noise.
Imported bearing and triangle belt, made the transmission case and belt pulley life-long.
Advanced structure ensures pumps long time trouble-free operation.
