The GX grinder pump has a suction-assisted cutting system that can grind solids. These pumps are used wherever dirty liquid needs to be pumped through relatively small-diameter pipes, often existing pipes. Applications: domestic wastewater, liquids containing solids, and any situation where high pressure is required.
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 GX pumps’ axial cutting system with a hardened steel blade uses suction to effectively grind domestic wastewater. The blade, which spins inside the pump inlet, acts 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 the precisely adjustable plate make it very unlikely for debris to wrap around the rotating parts. Protrusions on the plate effectively break up the braid that often forms around the blade (usually the cause of impeller blockage).
GX grinder pump installations
GX pumps are designed for domestic wastewater pumping stations and compact pumping stations often located in buildings. Pumps with an axial solid-waste grinding system can be successfully installed on coupling feet, e.g. type EASY 3.1 or EASY 3.2, in DRENO BOX pumping stations, or on DUTY 50 coupling feet.
Control of 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 using 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 prevents water from 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 installation of an elbow connection for a flexible hose with a clamp or quick coupling,
• 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) can be made to order.
