Float version
The GX grinder pump features a suction-assisted cutting system that grinds solid matter. These pumps are used wherever dirty liquid needs to be pumped through relatively small-diameter pipes, often pipes that are already installed. Applications: domestic wastewater, liquids containing solids, and any situation requiring high pressure.
Features
All major components are made of GG20 cast iron. The mechanical and lip seals in the oil chamber ensure the product operates correctly.
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, making it possible to pump wastewater through narrow pipes as small as DN40. The blade shape and precisely adjustable disc keep the risk of debris wrapping around rotating parts very low. Protrusions on the disc effectively break up the braid that often forms around the blade (and is usually the cause of impeller blockage).
GX grinder pump installations
GX pumps are designed for domestic wastewater pumping stations and compact pumping stations commonly found in buildings. Pumps with an axial solids grinding system can be successfully installed on coupling feet such as the 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 the built-in float switch or by an external signal, e.g. from an M121 or M131 controller (single- or three-phase). For customers with more demanding requirements, we can offer advanced control systems using 3, 4 or more float switches, a hydrostatic probe, or a system tailored to the customer's specifications.
FEATURES
• Axial shredding system,
• Hardened steel blades ensure effective cutting of debris,
• The oil chamber prevents water from entering the motor directly if the seal behind the impeller is damaged,
• Side flanged outlet with an additional thread allows installation on a coupling foot and easy installation of an elbow connector for a flexible hose with a hose clamp or quick coupling,
• Built-in float switch controls pump operation and protects it from running dry,
• T1-T2 thermal protection built into the motor winding, connected to a dedicated control panel,
• 10 m H07RNF power cable with a starter box,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions for liquid temperatures up to 60°C with the pump fully submerged (not for continuous operation) are available to order.
