Common pump model code

LG - High rise building water supply pump

GDL vertical multi-stage centrifugal pump

DL - Multi stage vertical clean water pump

ISG - single-stage vertical pipeline pump

ISW——Single stage horizontal clear water pump

TSWA - Horizontal Multi stage Centrifugal Pump

CDL - Vertical Multi stage Stainless Steel Stamping Pump

DA1- Multi stage horizontal clear water pump

QJ - Submersible Electric Pump

The meaning of the model of the tower free water supply pump is: such as 40LG12-15; 40- Inlet and outlet diameter (mm); LG high-rise building water supply pump (high-speed); 12- Flow rate (m3/h); 15- Single stage head (M).

200QJ20-108/8.200- indicates machine base number 200; QJ - submersible electric pump; 20 flow rate of 20m3/h; 108- Head 108M; 8- Stage 8.

The basic components of a water pump are: motor, coupling, pump head (body), and machine base (horizontal).

The main parameters of the water pump are: flow rate, represented by Q in M3/H, L/S. Head, represented by H in M

The cavitation allowance (M) parameter is very important for clean water pumps, especially when used for suction type water supply equipment.

The rated current parameter (A) is very important for submersible pumps, especially when used for variable frequency water supply equipment.

　　Constant pressure variable frequency water supply equipment water pumpThe main parameters of the motor are motor power (KW), speed (r/min), rated voltage (V), and rated current (A).
