Liquid Oxygen Pump


Sanghi –Acetone Pump:

It is a geared motor pump coupled with motor by love-joy coupling. The pump has two parts mainly suction port and the discharge port. The suction port is provided with extended pipe and foot value to reach the bottom of the acetone drum.

Liquid Oxygen Pump

Liquid Gas Cylinders

LGC's are small liquid cylinders with in built pressure building & evaporating coil to allow both gas as well as liquid withdrawal. It can be transported to & from customers site with liquid filled in just like high pressure gas cylinder. This facilitates larger quantity of product transfer in liquid form than in Gaseous form. It is ideal for Liquid N2, Oxygen, Argon CO2 & N2O.


Liquid Oxygen Pump


High Pressure Atmospheric Vaporizer for LOX/LIN Design.
Construction of Tubes : Copper
Construction of Frame : Mild Steel

Operating Pressure & Design Pressure will vary depending upon the users requirement. However, the Vaporizers from operating pressure of 8 Kg/cm2g to 200 Kg/cm2g are available.

The Vaporizers are used for converting the liquid form of product (i.e. O2,N2,Argon) to the gaseous form. This transformed gas can be supplied in pipe line through Low Pressure Vaporizer or can be filled in cylinders through High Pressure Vaporizers .

Liquid Oxygen Pump


We offer online, digital, electronic analysers with mounting & portable type for monitoring purities of Oxygen, Nitrogen, Argon and other gases. This indicator is a convenient and handy instrument for field applications where a quick, easy and accurate measurement of oxygen is required. The sensor being located within the instrument requires the gas sample to be delivered to inlet port. This instrument is ideal where the sample is available at a slight positive pressure.


Liquid Oxygen Pump

Gas Compressors

This is a reciprocating machine, with crank gear, piston rod, piston, cylinders. The machine is used for building up pressure of Oxygen, Nitrogen, Nitrous Oxide gas for filling the gas into Cylinders. These are available in various capacities and consist of following :
