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 blade in GX pumps ensures effective shredding of the contents of domestic wastewater. The blade 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 blade and the precisely adjustable disc make the risk of waste wrapping around the rotating parts very low. Projections extending from the disc effectively break up the braid that often forms around the blade, which is usually the cause of impeller blockage.
GX Grinder Pump Installations
GX pumps are intended for domestic wastewater pumping stations serving single-family homes, as well as for 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 on DUTY 50 coupling feet.
Control of a Household 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 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 allows 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 free leads,
• 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).
