The twin screw pump is a positive displacement pump. This type of pump has strong self-priming performance and is suitable for transporting viscous liquids containing solid particles and fibers, or even semi-solid liquids, with a maximum transport viscosity of 300,000 cst centipoise. Advanced internal structure, no shear, high head, strong self-absorption, relatively small size, etc. The biggest feature is that it can be mixed with oil and gas.

Performance parameter:

Flow range:0.1m³/h-2000m³/h;Output pressure:0-4MPa;Delivery viscosity range:1-300000Cst;Delivery temperature range:-40℃-320℃

Applicable fields:

Chemical and petrochemical: lubricating oil, hydraulic oil, cutting oil, cooling oil, cooling oil, wax, tar, light oil, liquefied petroleum gas, crude oil, heavy oil, leachate.

Material customization:

Shell materialHT250/QT400-15/Q235/45#/0Cr17Ni4Cu4Nb/316L stainless steel/2205/2206
Pump cover material/QT450/Q235/45#/304 stainless steel/316L stainless steel/2205/2206
Spiral sleeve and shaft material2Cr13/3Cr13/0Cr17Ni4Cu4Nb/2205/2206 (heat treatment process: quenching, carburizing, glow ion desalination)

The pump casing can be selected with a thermal insulation jacket structure

Can play the role of heat preservation, the highest conveying temperature is 320℃ (the heat medium that can be used is: heat transfer oil, steam, circulating water, and electric heating)

Sealing form:

There are three types of sealing

1. Packing and sealing: The packing and sealing materials are carbon fiber, polytetrafluoroethylene, four-corner aramid, etc.

(Suitable for medium with high temperature, solid particles in the medium, and strong abrasive medium).

2. Skeleton seal: the dense material of the skeleton is fluorine rubber.

(Suitable for working conditions with low conveying pressure, slight particles in conveying medium, and temperature not exceeding 250°C).

3. Mechanical seal: The materials of mechanical seal ring include silicon carbide, tungsten carbide, cemented carbide, graphite ring, etc.

(With the flushing system, it is suitable for the transportation of high and low temperature media, and it is suitable for pure and lubricating media under normal conditions. The pressure bearing capacity is stronger than that of the skeleton and packing seal.)
