China PUMP IDENTIFICATION

PUMP IDENTIFICATION CODES

Every China pump has a nameplate attached to the base. The pump serial number and identification code are stamped on the nameplate.

The pump identification code is made up of digits and letters arranged as follows:

A. The intake diameter is expressed in inches, such as 1.5, 2, 4, 10, 20, 36, etc.

B. The discharge diameter is also expressed in inches, such as 1, 1.5, 3, 8, 18, 36, etc. Note: Series ‘A’, Type pumps are identified by discharge diameter expressed in millimeters – the intake diameter is not specified.

C. The frame of the pump consists of the base and the bearing assembly. The size of the base is identified by one or two letters, such as B, C, D, ST, etc. The size of the bearing assembly may be the same or have a different designation.
