screw pump

Single screw pump is used in all fields widely to feed kinds of medium, running at a constant pressure continuously.

Wide Application

Single screw pump is used in all fields widely to feed kinds of medium, running at a constant pressure continuously, without pulse and damage when feeding medium, and change the gauging aim through adjusting rotation speed.

Feeding Medium

This product is applicable for feeding medium which has the following properties.

High solid content (diameter of the biggest particle is 50mm) or no solid content

Medium with all viscosities (1mPas~3,000,000mPas)Medium that is easy to be generated and swelledShearing sensitive mediumMedium with erosionMedium with/without self lubricationErosive medium (PH=0~14)Adhesive mediumToxicity hazard medium

RotorFrom friction and erosion resist metal rotor to no damage pottery rotorStator   Stator material is formed in steel pipe, the two ends are sealed and the inner cavity is made of kinds of spring rubber materials and plastics. A horn structure is taken at the stator entrance for flowing the medium conveniently. Driving System   Through a coupling mandril with universal joints at ends, driving shaft and extension shaft will pass power to rotor. Large Flow And High PressureFlow range: 0.2m3/h-200m3/hThe highest pressure range reaches 18bar.Pump Suction Chamber And Extraction Body

Exit and entrance are designed according to Germany DIN standard and international standard, in flange form or thread form which is easy for liquid flowing, and the inner cavity is made of cast iron, NiCr steel, stainless steel, rubber lining cast iron and other special materials.Many Assistant Combinations   A same driving part can be matching with four different designed rotors/stators to provide you a best application scheme.Widely Material Selection   For the purpose of different application in fields, different metal materials can be selected from cast iron, NiCr steel to acid resisting material, Hastelloy alloy, and titanium alloy. Spring materials which are friction, oil, acid and alkali resisting can be selected such as natural rubber, NBR, EPR, and fluoro rubber. For strong erosion medium, pottery or plastics can be selected. When spring material cannot be selected for the reason of high temperature or the medium has some chemical elements, hard material stator or rigid stator can be selected.Multi Axial Seal Forms   As per customer’s requirement, mechanical seals from single end surface mechanical seal (with/without rapid cooling), double end surface mechanical seal (back-to-back and series mechanical seal) to diaphragm seal; also packing seal, water loop seal and special seal can be selected. For toxicity hazard medium, non-leakage magnetic drive can be provided.Other Properties   The best upward height reaches 8m mercury column, revolving and feeding in double directions, free to installationRunning freely, stably, with low noise, no pulse, no shearFeeding medium temperature range: -20°C~+180°C
