Which is better, a gear pump or a screw pump?
Screw pumps… We use screw pumps in all our compressor units… Gear pumps are used in the oil circuits of those pump units
For large units, screw pumps are generally chosen as oil pumps, while for smaller units such as reciprocating machines, gear pumps are more commonly used. Screw pumps have a compact structure, with virtually no pulsations in flow rate and pressure; they also offer high pressure. Compared to gear pumps, they operate more smoothly with less vibration and noise ； Long lifespan and high efficiency.
Screw pump for large volumes, gear pump for small volumes
Gear pumps have a low cost, but their lifespan is relatively shorter compared to twin-screw and triple-screw pumps. Screw pumps, on the other hand, are more expensive; there is no absolute best choice – the decision depends on the operating conditions. For many applications, gear pumps are a good option as their cost is much lower than that of screw pumps.
Screw pump.....................
Screw pumps are widely used; domestic technology in this area has been advanced for a long time, offering good value for money~~~~ Gear pumps, well… It’s hard to put into words~~
Screw pumps are more reliable to use; our factory’s compression units employ these
For use as a lubricating oil pump in machinery, screw pumps are becoming increasingly popular; it is recommended to choose screw pumps
