Universal liquid oxygen pumps are designed for assembly in air separation unit that works by pumping liquid Oxygen and gasifying the same in Heat Exchangers for final filling as gas in Cylinders. The pump is designed in accordance with the plant size and the liquid produced is constantly pumped off so the control of liquid feed is not required.

Liquid Oxygen pump for air separation unit of oxygen plant

Liquid Oxygen Pump for the plant consists 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 60 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.

Oil Free Pump
