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

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

Vertical multistage pumps are vertical, single suction, multistage, sectional centrifugal pumps suitable for urban water supply and central heating systems. It is used to transport clear water or liquids with physical and chemical properties similar to clear water. The temperature of the pump convey Read More
