An Archimedean screw pump is a positive displacement pump that draws fluid into the buckets that formed between the screw flights at the inlet bay and by its rotation transfers the fluid upwards upto the specified Head range. The pump can lift wide variety of fluids that varies from cleanest raw water to the muddy waste water with floating debris.To get more news about screw pump, you can visit hw-screwpump.com official website. This type of pump is designed for pumping extremely large volumes of working fluid: in a minute, this unit capable of moving up to 5.5 thousand liters of oil at a pressure of up to 120 bar.

A distinctive feature is the ability to work even in super-heavy conditions: for example, oil production at low temperatures. In addition, you need to buy a screw pump if the hydraulic system uses a working liquid with high viscosity.  SCREW PUMPS: CLASSIFICATION All screw pumps can be conditionally divided into three groups, according to the number of screws:

single-screw. Designed to work with various liquids, including chemically active, whose the temperature does not exceed 80 degrees, and the viscosity is 4600 cSt. The concentration of suspended liquid particles is not should exceed 5% of the mass of the liquid itself; twin-screw. They can be of the type: ○ 2ВВ: designed to work with water, including mineral and sea water with oil impurities, whose viscosity is not exceeds 260 cSt, and the temperature is 80 degrees. On request, a complete set of special electric motors is possible, explosion proof;

○ 2ВГ: designed for pumping fuel oil and other liquids, whose viscosity does not exceed 1500 cSt, and the temperature - 80 degrees. The pump can be designed to work with liquids with temperatures up to 150 degrees.

three-screw. Designed for pumping non-aggressive liquids with lubricating properties, whose the temperature does not exceed 100 degrees (up to 150 degrees is possible on request), and the viscosity is 1500 cSt. If you need a screw pump, you should buy it on our website.
