Liquid is delivered in axial direction continuously without agitation, so screw pump has constant capacity and perssure, smooth running, small vibration and low noise.
Screw pump has a very high suction capability. It needn't bottom valve and other equipments.
The drive screw is driven by motor and the idler screw is driven by the pressured liquid, between the drive screw and idler screws, screw set and insert an oil film is formed, so the mechanical is minimized and a longer life is ensured.
Screw pump has single suction、double suction and horizontal installation、vertical installation pump. In order to ensure the safe working of pump, motor, piping system, screw pump is equipped with safety values.

The three spindle scew pump is suitable to carry various kinds of non-corrosive oil without contents of solid grains and liquids similar to lubricating oils, the viscosity of mediums is from 1.2 to 100'E(from 3to 760mm'/s), the temperature is equal to or less than 150℃.
The flow range is from 0.2 to 400㎡/h, the working pressure is from 0 to 16MPa.
