Sanghi - Liquid Oxygen Pump by Cryo Corp

The single action piston pump, pumps liquid Oxygen & gasify the same in heat exchanger for final filling as gas in cylinders at a pressure of 165 kg/cm². Liquid Oxygen Pump when is operated, the liquid oxygen from the main condenser enters the outer jacket of the pump. Some of this liquid evaporates due to heat produced in pumping and the vapor is passed to the upper column as gas. The major part of liquid oxygen is taken into the pump cylinder and compressed out by the piston stroke. This high pressure liquid oxygen passes through two non-return valves into the heat exchangers and then to the cylinder filling rack.

Spares Requirement:

Liquid Oxygen Pump, pumps high pressure liquid Oxygen to the filling manifold. This pump is to be maintained properly for its efficient functioning. Some of the spares imported are listed below-

• S.S.Liner (Size- 20 mm to 44 mm)
• S.S.Piston (Size- 20 mm to 44 mm)
• Piston Rings
• Cross head
• Gland Packing
• Safety valves
• Crank shaft
• Oil Wiper Rings
• Non-Return Valves of sizes 1/2″, 5/8″ & 3/4″
• Connecting rod with bearings
• Brass Gland Nut & Cylinder Head Nut

Special feature of our product line:

• All SS and Brass products are made from SS 304 and extruded brass material. The constitution of the material is utmost important for workability at -175 °C of liquid oxygen. The size of liner made by u varies – 20 mm to 44 mm.
• Glass Field Teflon (GFT ) and Carbon Filed Teflon (CFT) is molded from imported Original DUPONT. Timely heat treatment and proper cutting prevents shimmer or deformation of the material if fitted properly in the Liner. We supply from 20 mm to 44 mm size suitable from 63 cu.m/hr to 600 cu.m/hr Oxygen Plant.
• Non-Return Valve is also heat treated using cryogenic heat treatment. The seat of the Non-Return Valve is treated with special heat treatment called Cryogenic Hardening in which the Seat is hardened at the ambient working temperatures of inlet and outlet.
