Float version
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 already installed. Applications: domestic sewage, 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 guarantee 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 the contents of domestic sewage. The knife rotating inside the pump inlet acts like a milling cutter, cutting and grinding everything into small pieces, allowing sewage to be pumped through thin pipes with diameters as small as DN40. The shape of the knife and the precisely adjustable cutting plate make the risk of waste wrapping around the rotating parts very low. Projections extending from the plate 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 intended for domestic and household sewage pumping stations and for compact pumping stations often located inside buildings. Pumps with an axial solids grinding system can be successfully installed on coupling feet, e.g. EASY 3.1 or EASY 3.2, in DRENO BOX pumping stations, or on DUTY 50 coupling feet.
Controlling the Domestic Grinder Pump
GX series pumps can be controlled either by a built-in float or by an external signal, e.g. 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 floats, 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 with a clamp or quick coupling,
• The built-in float controls pump operation and protects it against dry running,
• T1-T2 thermal protection built into the motor winding, connected to a dedicated control panel,
• 10 m H07RNF power cable terminated with a starter box,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions for liquid temperatures of up to 60°C with the pump completely submerged can be produced to order (not for continuous operation).
