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

What is the reason for a screw pump not starting? There are more reasons for this situation, such as motor failure, inadequate pump filling, pump cavity with residual media and solidification, stator and rotor with too much interference, shaft seal packing is too tight, etc. can cause difficulties i Read More

What are the reasons for vibration in the operation of a screw pump? Relatively common reasons lie in improper installation or failure of components within the pump, in addition to the unexpected working conditions can also be considered to lead to some kind of failure, in order to ensure the stabil Read More

Screw pumps have excellent adaptability to working conditions and can still operate stably in a variety of harsh environments, but after a long time there is inevitably dirt and scaling, especially if the internal movement components are seriously scaled and also clogged, how can screw pumps prevent Read More

In the world of industrial manufacturing, the general definition of the term unit operation is fairly benign: the basic steps in a process. However, in the world of chemical processing, unit operations are much more than that. That is, they are the blueprint for a series of production stages that a Read More

Four Screw PumpIn general, these types of screw pumps are a two-screw pump with two screws on each rotor, however, each pump rotor contains two screws that revolve in opposing directions.The four screw pump suctions fluid into the suction port, which is then divided evenly and sent to both ends of t Read More

Screw PumpsScrew pumps are a well-known form of positive displacement pumps in which a series of screws move in a 360° rotational motion within a casing. They are also known as “water screw pumps”. They are also recognized as the most reliable pump for a variety of operations due to their superior s 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 flow rate of the screw pump is fixed, at a fixed speed, the flow rate of the single screw pump can be fixed, there are few pulses or large fluctuations in the flow rate, stable flow is a major feature of the screw pump, and even when dealing with complex composition of the slurry type of liquid 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
