Screw pump structure is simple, not only stable and reliable when running, but also very durable, and has the advantage of low input costs, is currently one of the mainstream transport equipment, but in order to further extend its service life, know how to maintain the screw pump is still very neces Read More

Screw pump in the normal drive flow is stable without pulsation, with a high processing efficiency, but if the unexpected working conditions lead to some kind of failure, it will affect the flow parameters, recently there are also customers consulting screw pump displacement on how to do, in this re Read More

InstallationWhen assembling the pump, the relevant parts that need to be lubricated (such as bearings, universal joints, etc.) must be filled with grease, usually 2/3 of the cavity volume.Check whether the connection parts of the unit are firmly fixed.The pump unit (including the independently insta Read More

As long as the motor-driven pump, if idling for a long time there is a risk of burning the pump, recently there are customer enquiries about how long the screw pump will be bad idling, which mainly depends on the motor temperature rise, due to the lack of media cooling and lubrication, idling will b Read More

The use of screw pumps is extremely wide, a comprehensive selection of various types of screw pumps, only from the transport of media, its ability to transport a variety of media more than all other pumping capacity. For the same type of progressive cavity pump, their characteristics and application Read More

Can a screw pump pump sand? Mainly depends on the specific gravity of the medium, if the liquid contains some particles of sediment, usually can be pumped normally, such as pond sediment water, industrial production wastewater, underground well water, etc., as long as the corresponding calibre of th Read More

Performance parameters of the screw pump(1) pressure: hydraulic engineering applications of the three screw pumps commonly used working pressure range is 2.5 ~ 20MPa, individual can be as high as 35 ~ 40MPa.(2) displacement: screw in the meshing drive process, due to the formation of the cross-secti Read More
