The GX grinder pump features a suction-assisted cutting system that grinds solids. These pumps are used wherever dirty liquid needs to be pumped through relatively small-diameter pipes, often ones that are already installed. Applications: domestic wastewater, liquids containing solids, and any situation requiring high pressure.
Specifications
All major components are made of GG20 cast iron. The mechanical and lip seals in the oil chamber ensure the product operates properly.
GX grinder pump – Advantages
The vacuum-assisted axial cutting system with a hardened steel blade in GX pumps effectively grinds the contents of domestic wastewater. The blade rotating inside the pump inlet works like a milling cutter, cutting and grinding everything into small pieces so wastewater can be pumped through narrow pipes as small as DN40. The blade’s shape and precisely adjustable plate make it very unlikely that debris will wrap around the rotating parts. Protrusions on the plate effectively break up the rope-like mass that often forms around the blade (usually the cause of impeller blockage).
GX grinder pump installations
GX pumps are designed for domestic sewage pumping stations and compact pumping stations, often located in buildings. Pumps with an axial solids grinding system can be successfully installed on coupling feet, such as EASY 3.1 or EASY 3.2, in DRENO BOX pumping stations, or on DUTY 50 coupling feet.
Controlling a domestic grinder pump
GX series pumps can be controlled either by a built-in float switch or by an external signal, for example from an M121 or M131 controller (single- or three-phase). For more demanding customers, we can offer advanced control systems with 3, 4 or more float switches, a hydrostatic probe, or as requested by the customer.
FEATURES
• Axial shredding system,
• Hardened steel blades ensure effective cutting of contaminants,
• The oil chamber protects against water entering the motor directly if the seal behind the impeller is damaged,
• Side flange outlet with an additional thread allows installation on a coupling foot and easy fitting of an elbow connection for a flexible hose secured with a clamp or quick coupling,
• T1-T2 thermal protection built into the motor winding, to be connected to a dedicated control panel,
• 10 m H07RNF power cable with bare wire ends,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions designed for liquid temperatures up to 60°C with the pump fully submerged (not for continuous operation) can be made to order.
