Double screw pump 800series

Basic Info

Model No.: 800series

Product Description

There are two types of double screw pump, which are sealed and not sealed, and the twin screw is divided into two types: double suction type and single suction type, according to the medium from one end or from both ends.

Twin screw pump, screw pump meshing, which uses mutual engagement, do not touch the two screws for pumping liquid.

The twin screw pump is a double suction non closed double screw pump. One end of the active screw extending from the pump is driven by a prime mover. The active screw and driven screw have different screw threads. The screw and the pump body are closely fitted. Driven screw is driven by active screw through synchronous gear.

Structural characteristics

The pump adopts a double suction structure, and the two ends of the screw are in the same pressure chamber, and the axial force can be self balanced. The bearings at the two ends are externally installed and lubricated by grease (grease) separately, thus being free from the influence of the conveying medium. The two screw is driven by a pair of synchronous gears, and there is no contact between the teeth of the screw, but there is a small gap, and the impurities in the medium can not produce direct wear on the tooth surface of the screw (except for the scour). In addition to some small displacement pumps (below 2W.W4.0), generally with the pump body with a flow type safety valve, when the discharge pressure exceeds the rated value, there is a certain protective effect. There are two kinds of inlet and outlet directions on the pump body, one is horizontal and horizontal, the other is horizontal and vertical, and users can choose according to their own needs.

Characteristic advantages

1. The conveying liquid is stable, no pulsation, no agitation, little vibration and low noise.

2, self-priming performance is very strong, multiphase, gas rate is not higher than 80%, the sediment concentration is less than 500g/m3.

3, the external bearing structure, the use of independent lubrication, can transport all kinds of non lubricating media.

4, the use of synchronous gear drive, the two rotor contact, even if a short time idle.

5. The pump body has a heating sleeve, which can convey various low viscosity or high viscosity media with clean or solid small particles (the diameter of the particles is less than 0.12-0.2mm).

6, the correct selection of materials, and even transport a lot of corrosive media.

7, double suction structure, there is no axial force on the rotor.

8. Shaft ends adopt mechanical seals or bellows mechanical seals. They have long service life, less leakage and wide application scope.
