The GD grinder pumps are of cast iron and 304 stainless steel construction. They are used in sewage stations and for servicing individual, or groups of, houses where drainage by gravity is not possible. They are ideally suited to applications where effluent is required to be pumped over a long distance, through a small bore pipe. The cutting mechanism is constructed of hard wearing chrome steel and is designed to pulverise sewage, soft solids or shreddable fibres. The high heads produced, with only limited horsepower motors, also make them suitable for agricultural disposal systems that feed sprinklers. In industrial applications they are used for pumping fibrous material. The 410 stainless steel shaft has a double mechanical seal (in an oil chamber) in silicon carbide and carbon ceramic.
The models GD-15 and GD-20 are available free-standing or for guide rail mounting when supplied with the guide rail (auto-coupling) kit. The GDH-15 is available free standing only. Supplied with 10 metres of heavy duty rubber power cable.
