HCP GF Series- Grinder pumps

The GF pump features an efficient grinder mechanism at the inlet to the impeller. All foreign matter that enters the pump will be cut up into small particles. The result is a fine slurry that can be transported through pipes as small as 32mm in diameter.

They were specially designed for pressure sewage systems.

  • Fitted with a combination of chromium alloy and stainless steel parts
  • The cutter device is mounted on the shaft and the stationary cutting ring with axial teeth is mounted at the pump inlet
  • The range consists of 1.5kW, 2.2kW and 3.7kW pumps. They are available in single phase 240Volt and three phase 415Volt
  • Pumps feature a double, back to back mechanical seal (Inner = Carbon vs. Ceramic, Outer = Silicone carbide vs. Silicone carbide) The seal is located in the oil housing and runs independently from the pumped product. It is thus not dependant on product for cooling or lubrication
  • Pumps are fitted with a motor protector “auto cut” thermal device. This protects the motor from burning due to overloading etc.
  • Grinder pumps are very efficient and are often only required to run for an hour per day. 


Durable heavy duty cast iron construction.
Grinder is complete unit, light weight, compact, and portable, easy to be installed.
Double protection at connection box: barrier grommet, barrier epoxy, prevent water contamination of the motor area, assuring a long-term reliable operation. Additionally, epoxy encapsulation and stripped leads positively eliminate wicking from the cable. Two balls bearing construction support shaft and rotor.
Dry type motor with high efficiency and low current. Equipped with Auto reset motor protector, prevent the motor damaged from abnormal heat and current.
The dual silicon carbide mechanical seal system, extra oil seal protection, and WD water detector protects the motor from sewage contamination, to provide you exceptionally long pump service.
An excellent vortex impeller and casing water cavity housing design. Provide high efficiency and power saving, handling ground slurry and sewage without clogging or binding.
Radial cutter and cutter ring: corrosion resistant material, hardened to 55-60 Rockwell C.


Specialized one single strong shaft with impeller and radial cutter, dramatically reduces the torque requirement on the motor, cuts with less horsepower; and increases the pump's efficiency. What's more, it prevents clogging with some troublesome objects such as sanitary napkins , plastic, rubber, disposable diapers and cloth items. The design of HCP grinders prevents clogging, binding and roping, it chop up almost anything and everything in order for you to get a continuous, long-term pumping service.
