Progressing Cavity Screw Pump by Farhat Enterprise

Applications:

Type 'BD' Screw Pumps are used for pumping all types of viscous liquids in a host of industries such as mining, chemical, paint food processing, effluent treatment, dairies and breweries, distilleries, sugar, paper, ceramics, cosmetics paper coating plant, medicines and other industries.

Design & Operating Principles:

The Gita progressing cavity screw pump is valveless positive displacement pump. The main pumping elements are rotating screw (rotor) of circular cross section and in the form of helically wound single pitch screw. The stator has twice the pitch length of the rotor. As a result closed cavities are formed between the two pumping elements, in which the pumped material is transported continuously is an axial direction with every revolution of the rotor in the stator.

Material of Construction:

Gita types "BD' screw Pumps are available in a wide variety of materials of construction, to suite individual customer requirement and per character of the pumped liquid. Standard material of construction is as under:

Specifications:

• Rotor - EN Steel duly heat treated, hard chrome plated and AlSl - 3.4, AlSl - 316, hard chrome plated and other highly alloyed steels
