Piston Positive Displacement Pumps are mainly used for air separation products: filling of liquid oxygen, liquid nitrogen, liquid argon, liquid carbon dioxide, air supply systems. The units are mainly single row, double row and three-row reciprocating pumps. Refer to each parameter table for specific parameters.
Application
- Such pumps are mainly used for liquid oxygen, liquid nitrogen, liquid argon and liquefied natural gas.
- Filling of all kinds of cylinders with light, medium and high loads
- Filling of all kinds of storage tanks
- Air supply, air distribution systems
Main Technical Parameters
Flow: 50-6000 L/h
Maximum exit pressure: 16.5 Mpa-150 MPa
Performance Features
- A such pump has classic design and stable performances; its service life can reach 20 years;
- A high vacuum jacket pump head is used, and the vacuum degree reaches 10-5 torr so as to reduce cold loss;
- lts seal is reliable: the service life of packing can each 150.000 times/ cvlinder and the service life of the piston ring is as long as 300,000 times/ cylinder;
- An auxiliary gas sealing device can be equipped to further enhance the service life of the sealing element
- Maintenance is convenient: it merely takes two hours to perform a routine maintenance;
- The pump can be continuously operated for 24hours.
