The GD and GDH manufactured by the industry leading experts from APP, are a range of heavy duty sewage grinder/sewage macerator submersible pumps, ideal for use where high heads or long distances prevent the use of standard submersible pumps.
They include a heavy duty construction suitable for pulverising and pumping organic waste to the main sewage line or treatment plant and are ideal if only a small bore discharge pipe is available.
The APP GD and GDH grinder pumps have cast iron cutters and grinding rings which allow for up to 28,000 cuts per minute.
In addition, all of the GD and GDH sewage grinder pumps include double oil bathed mechanical seals for reliability and longevity. The GD and GDH range of sewage submersible macerator pumps are one of our toughest and most reliable choice for domestic and commercial sewage grinder applications.

1 1/4 inch 32mm BSP female threaded outlets as standard. Furthermore, the GD20 range of pumps can be used on a guide rail system by purchasing the auto coupling kit which includes coupling foot, claw and top bracket.
