Pump compositions
We offer horizontal single stage, end suction with vertical discharge. The “back pull out" design allows for the maintenance of the pump without disturbing the pipe work connected to the casing or the pump alignment.

Pump body: The pump body uses an efficient volute form and the flange connection standard is: GB/T17241.6 PN1.6-1998 (cast iron), GB/T9113.1-2000 (steel) or PN1.6MPa (16bar), which can all be used in conjunction with the following flanges at the same level: BS4504 flange, DIN2533 flange, ISO7005.1 flange, and ISO7005.2 flange.

Impeller: closed impeller

Shaft: pump shaft with larger size is more reliable for pump operation

Shaft seal: mechanical seal and packing seal

Bearing: Grease lubrication and oil lubrication are available for bearing lubrication . When the working environment temperature is higher and the load is larger, oil lubrication should be used.
