Liquid Oxygen Pump

Product Description

Liquid oxygen/nitrogen pump comprises of a stainless steel inside liner with liquid inlet and evaporated gas outlet ports. There are no valves on these ports, which are closed by the piston itself on the pressure stroke. The third outlet is the main discharge outlet with the two non-return ball valves. The two ball valves remain firmly closed during suction stroke, due to high pressure in partly filled cylinders. To ensure that these valves are fully closed, a positive pressure of about *0 kgs/cms2 must be maintained on it. When a fresh batch of cylinders is taken for filling, open the manifold valve slowly or use a spare batch of cylinders to ensure positive pressure on these valves.
