3G series products, low vibration, low noise, no pulse, stable pressure during operation,Can be customized vertical, wall-mounted, immersed and other installation forms.

Performance parameter:

Flow:0.3m³/h-590m³/h;Output pressure:0.2-2.5MPa;Delivery viscosity range:2-1500Cst;Delivery temperature range:200℃

Applicable fields:

It is suitable for industries such as petroleum, chemical industry, shipbuilding, electric power, medicine, metallurgy and so on.

The 3G three-screw pump can transport fuel oil, lubricating oil, hydraulic oil, cutting oil, cooling oil, coolant, tar, etc.

Material customization:

Shell materialHT200/QT450-10/45#
Screw material16MnCr5/38CrMoAlA (heat treatment process: quenching, carburizing, glow ion desalination).
Bushing materialHT200/rare earth copper-molybdenum ductile iron/ZG109/ZCuSu5Pb5Zn5 (tin bronze)

When transporting special media at abnormal temperatures, the housing of the pump can be increased with heat preservation and cooling jackets,

Can play the role of heat preservation and cooling. (The heat medium that can be used is: heat transfer oil, steam, circulating water)

Sealing form:

There are four types of sealing

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

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

2. Skeleton seal: The frame seal materials are nitrile rubber, fluorine rubber, Teflon and other materials.

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

3. Mechanical seal: The material of mechanical seal ring includes 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. Under normal conditions, it is suitable for pure and lubricating media. The pressure bearing capacity is stronger than that of the skeleton and packing seal).

4. Magnetic seal: suitable for working conditions such as flammable, explosive, volatile, easy to leak, and toxic.

The biggest advantage of the magnetic seal is that there is no leakage of the medium and no air leakage, which plays a huge role in the safety and cleanliness of the production environment. It is not sensitive to abnormal pump inlet pressure or unconventional working conditions.

(Magnetic sealing material: isolation sleeve material is divided into 45#/304/Hastelloy C-276. Magnetic material: samarium cobalt alloy).
