Liquid oxygen pump

Delhi Cryogenics Products Pvt. Ltd. is a medium scale industry setup by a team of experienced, highly dedicated & skilled engineers working in the designing, manufacturing and commissioning of oxygen-nitrogen plants & acetylene plants for more than 20 years. As a leading and reputed company, it is engaged in manufacturing and Supplying Oxygen plants, Nitrogen plants and Acetylene plants in India. Incorporated in 1987 at New Delhi, India, the company is equipped with latest and state of the art technologies. We supply a broad range of oxygenmedical and industrial gas plants and processing equipment for both industrial and medical customers all over the world.
We offer technically advanced oxygen plants, liquid oxygen nitrogen plants, oxygen gas plant, cryogenic liquid oxygen plant, nitrogen generators, liquid oxygen generators, acetylene gas plants and more. Designed in compliance with international quality standards, these plants also help in the filling of gas pressure in cylinders.
We manufacture cost-effective, safe and reliable oxygen generating systems for high quality industrial and medical use. Currently our oxygen plants are being exported to many countries worldwide, serving markets for bottling cylinders, industrial gas cutting of steel, production of steel glass Petrochemical industry, Fabrication, Medical use in Hospitals, Oil & gas Industry, and Animal Husbandry.
Our Process is based on the latest design and technology of Liquefaction of AIR where the basic principle of deep refrigeration and cooling is used to liquefy the atmospheric air specially suitable to produce liquid oxygen-nitrogen and filling high pressure oxygen Nitrogen of high purity cylinders & bottles and safe to operate for production of medical and industrial oxygen because the pure oxygen can be filled directly into cylinders without coming into contact with the air or moisture



 
 

Liquid oxygen pump

Liquid Oxygen Pump is a single acting piston pump. It is used for filling in Oxygen into Cylinders upto a pressure of 155bar (kgs. /cm2). We design the pumps in order to avoid the leakages. In fact, leakage must also be carefully controlled or diminished to very low helium leak rates as oxygen seems a fire hazard. While manufacturing the products, we do not compromise with the quality.


The pump is 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. Control of liquid feed is not necessary, because the pump is designed in accordance with the plant size and the liquid produced is constantly pumped off.

Liquid Oxygen Pump for the plant 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, owing 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.
