Crude Oil Pumps

Our crude oil pumps are rotary pumps suitable for various flowable liquids. The conveyed materials include all kinds of dirty oil and so on.

It can realize flow regulation under constant pressure, suitable for frequency conversion control, and the effect of energy saving and consumption reduction is remarkable.

Struction Features and Advantages

crude oil pumps

Our crude oil pump (BY2GSZ pump) is a double-suction structure of a twin-screw pump(a type of rotary pump), and the spiral surface adopts an advanced Ω-shaped symmetrical form.

BY2GSZ pump is suitable for applications with large flow (generally more than 80 m3/h) or (and) high pressure (more than 3MPa). When the flow is small and the pressure is not high, it is recommended to use BY2GX single-suction pump instead.

The pump of this structure is a double-suction horizontal installation. Through the bearing positioning, the two screws do not contact each other in the bushing, and a constant gap is maintained between the tooth sides (the gap value is determined by the working conditions and the specifications of the pump itself). There is also a constant gap between the circle and the inner surface of the bushing. The transmission of the two screws is completed by the synchronous gear. In addition to transporting good lubricating media, this structure can also transport a large amount of non-lubricating media and media of various viscosities. As the core working parts screw sleeves do not touch each other, even if they run dry for a short time, there is no danger (3~5min). Therefore, it is widely used.

Low Noise And Long Life

Low vibration, no direct mechanical wear, low noise and long service life.

Stable Pressure And No Pulsation

Stable conveying pressure and constant flow rate. No pulsation or stirring medium, continuous and smooth supply.


Excellent self-priming performance. Even if the conveyed medium has a high viscosity.
