Such pumps are mainly used for filling high pressure gas cylinders at L-CNG natural gas stations. Theunits are mainly piston puups with single, double three cold ends.
Application
Filling of high pressure gas cylinders atL-CNG natural gas stations
Urban natural gas peak shaving station pipe networkgas supplementand pressure boost
Filling of LNG Dewar bottles
Main Technical Parameters
Flow: 500-10000 L/h
Maximum exit pressure: 1.0-35.0 MPa
Standard Configuration
Liquid inlet filter

Performance Features
All electric components are configured as per anti-explosion requirements.
A high vacuum jacket pump head is used, and the vacuum degree reaches 10s torr to reduce cold lossto the greatest extent.
The piston seal is made of special material and the service life of the piston seal is over 4,000 hours.
The exit pressure pulse is small and the motor load is steady.
The transmission case has a self-lubricating system and it operates in a steady manner. In addition.it is equipped with an oil temperature interlocking device to monitor the transmission case temperatureand the device interlocks with the control system so as to guarantee the safety of the unit.
