The use of multistage pumps is reflected in the high head water transport, the pump essentially belongs to the centrifugal pipeline pump, in the use of similar, suitable for industrial production and urban water system, commonly used for pressure transport, long-distance water transport, high-pressu Read More

Stainless steel multistage pumps CDLF type should be installed vertically on the ground and installed in such a way as to ensure that sufficient cold air enters the motor cooling fan. The arrows on the pump base indicate the direction of filling flow through the pump. To minimise the possible noise Read More

Third, the resistance loss in the inlet and outlet pipes of the multi-stage pump water flow is too largeSome pump users respond that the vertical height difference between the water source and the water tower or reservoir is less than the design head of the pump, but there is still the phenomenon of Read More

Multistage pumps are industrial pumps, widely used, multistage pumps also have several series, such as D type, DG type, DF type, DM type these models of multistage pumps belong to the horizontal multistage pump, DL type, DLR type, GDL type these belong to the vertical multistage pump, multistage pum Read More

A, multi-stage pump structure descriptionThe multistage pump is mainly composed of four parts: stator, rotor, bearing and shaft seal.1, The stator part of multistage pump is mainly composed of inlet section, middle section, spitting section and guide lobe, etc. There are tensioning bolts to clamp ea Read More

Difficult rotation or friction of rotating parts‍1) Bending of the shaftElimination measures: Straighten the shaft or replace as required.2) Incorrect running clearance between wear ringsElimination measures: Check if the clearance is correct. Replace the wear ring of the pump casing or impeller as Read More

The multistage pump is a type of centrifugal pump that relies on the change in volume of the pump chamber to achieve suction, compression and exhaust, and on the rotation of the impeller to obtain centrifugal force. Multi-stage pumps can be divided into many kinds according to the structure, each st Read More
