The GX grinder pump has a suction-assisted cutting system that enables it to grind solids. These pumps are used wherever dirty liquids need to be pumped through relatively small-diameter pipes, often already installed. Applications: domestic wastewater, liquids containing solids, and anywhere 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 correctly.
GX grinder pump – Advantages
The GX pumps’ suction-assisted axial cutting system, featuring a hardened steel blade, effectively grinds 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 as small as DN40. The blade’s shape and precisely adjustable plate make it very unlikely that debris will wrap around the rotating parts. Protrusions on the plate 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 residential domestic wastewater pumping stations and compact pumping stations often located in 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.
Controlling a residential 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 as requested by the customer.
FEATURES
• Axial shredding system,
• Hardened steel blades ensure effective cutting of contaminants,
• The oil chamber protects against water 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 connection for a flexible hose with a clamp or quick connector,
• T1-T2 thermal protection built into the motor winding, connected to a dedicated control panel,
• 10 m H07RNF power cable ending in a starter box,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions designed for liquid temperatures up to 60°C with the pump fully submerged can be made to order (not for continuous operation).
