SPIRAL CASING (SCREW) PUMP ASSEMBLY UODN 300-200-150, UODN-В 300-200-150

DESCRIPTION

It is used for pumping the following:
 - light (gasoline, diesel fuel) and dark (oils, fuel oil residue) oil products,
 - viscous mud oil residue from tanks, cisterns, tankers, storages.

Main advantages:
 - the pump assembly is equipped with a vacuum pump and may be used when it is necessary to pump oil products from open water bodies or earth storages, from major pipeline. It means that the vacuum pump enables self-feeding from a certain depth.
 - pumping of high viscous fluids up to 500 centistoke and high gas content fluids. Till the present day, it was possible only with the use of piston pumps.
 - pumping of fluids with high content of large hard particles (up to 20 mm).

The main feature of spiral casing (screw) pump assemblies is that screw wheels are used in them. The wheels have special screw blades with constant or variable pitch.

It gives us an inter-blade channel that enables low hydrodynamical load of blades and high anti-cavitation and power characteristics.

Spiral casing screw pumps are a pump option adapted from outer space engineering.
