The GX grinder pump features a suction-assisted cutting system that enables the grinding of solids. 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 wherever high pressure is required.
Features
All major components are made of GG20 cast iron. The mechanical and lip seals in the oil chamber ensure proper product operation.
GX Grinder Pump – Advantages
The vacuum-assisted axial cutting system with a hardened steel knife in GX pumps ensures effective grinding of the contents of domestic wastewater. The knife rotating inside the pump inlet works like a milling cutter, cutting and grinding everything into small pieces, allowing wastewater to be pumped through narrow pipes with diameters as small as DN40. The shape of the knife and the precisely adjustable disc make the risk of waste wrapping around the rotating components very low. Protrusions on the disc effectively break up the braid that often forms around the knife 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, often located inside 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 with 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, such as one 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 a system configured according to the customer’s requirements.
FEATURES
• Axial grinding 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,
• The side flanged outlet with an additional thread enables installation on a coupling foot and easy installation of an elbow connection for a flexible hose using a hose 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 free terminals,
• Warranty and post-warranty service,
• 24-month warranty.
Upon request, special versions can be manufactured for liquid temperatures up to 60°C with the pump fully submerged (not for continuous operation).
