Everyone is inquiring Screw pump We can always ask about the brand of Allweiler when we are in the market. This brand covers a wide range of pumps. There are many screw pumps in demand, especially single screw and twin screw pumps, twin screw pumps and Three screw pump It is used for pumping oil or other smooth liquids, non smooth liquids or liquids with poor smooth function. The characteristics of screw pump are: self-priming, very high power, very low noise level, very suitable for variable speed drive (FU). The liquid moves completely in succession, with almost no pulsation, turbulence, crushing or loss of smoothness. Functionality: single/dual channel self-priming; The main shaft has a special shape to form a seal chamber. When the contents of the main shaft move continuously along the axial direction from the suction force, the pressure side moves to the pressure side. Although the spindle rotates, no turbulence results. Uniform chamber volume eliminates crushing force. Main application occupation: wastewater, waste liquid, dosing, occupation, catering.

Germany ALLWEILER screw pump It has the following advantages:

① The rotating speed is low (generally 20r/min~90r/min), the mechanical wear is small, and cavitation will not occur.

② The flow channel is wide and can transport water containing solids.

③ The pump body structure is half open, and the operation condition in the pump can be observed.

④ The flow pattern at the suction side has little impact on the hydraulic function, has no special requirements for the suction tank, has small excavation depth of the foundation, is simple in the construction of hydraulic structures, and has low civil engineering costs.

Germany ALL The defects of WEILER screw pump are:

① Large scale and large floor area.

② Limited by machining conditions, the pump shaft cannot be too long, so the lift is low, generally not more than 10m.

③ The height of suction surface and outlet surface cannot change too much, or it will affect the working power and add energy consumption.
