Liquefied Gas Metering Pump

Two main types, the plunger and the diaphragm.
According to pumping temperatures and process requirements, the liquefied pump is also divided into two kinds: the normal temperature and the heat preservation.
Special valve set components for liquefied gas.
Pressure seal structure in the stuffing box for preventing the packing from cold hardening, or seal failure, due to leakage of medium.
Plunger pump for a minimal temperature of -110^oC.
Diaphragm pump for a minimal temperature of -70^oC.
