The GX grinder pump features a suction-assisted cutting system that enables the shredding of 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 anywhere high pressure is required.
Characteristics
All main 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 shredding of domestic wastewater. The knife rotating inside the pump inlet acts 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 plate result in a very low risk of waste wrapping around the rotating parts. Protrusions extending from the plate effectively tear apart the braid that often forms around the knife, which is usually the cause of impeller blockage.
GX Grinder Pump Installations
GX pumps are designed for domestic and household wastewater pumping stations as well as compact pumping stations often located in buildings. Pumps with an axial solid-waste grinding system can be successfully installed on coupling feet, such as the EASY 3.1 or EASY 3.2 types, 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, such as one 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 a solution tailored to the customer’s requirements.
FEATURES
• Axial grinding system,
• Hardened steel blades ensure effective cutting of contaminants,
• The oil chamber protects against direct water ingress into the motor if the seal behind the impeller is damaged,
• Side flanged outlet with an additional thread enables installation on a coupling foot and easy installation of an elbow connection to 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 terminated with a starting box,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions for liquid temperatures of up to 60°C with the pump fully submerged can be manufactured to order (not for continuous operation).
