Float Version
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 ones that are already installed. Applications: domestic sewage, liquids containing solids, and anywhere high pressure is required.
Characteristics
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 axial cutting system with a hardened steel knife in GX pumps ensures effective grinding 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 a diameter as small as DN40. The shape of the knife and the precisely adjustable disc make the risk of waste wrapping around the rotating parts very low. The protrusions extending from the disc effectively break up 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 sewage pumping stations as well as 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.
Control of the Household Grinder Pump
GX series pumps can be controlled either by an integrated float 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 using 3, 4 or more floats, a hydrostatic probe or a configuration 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 connection of an elbow fitting to a flexible hose using a hose clamp or quick coupling,
• The integrated float controls pump operation and protects it against dry running,
• T1-T2 thermal protection built into the motor winding, connected to a special 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 fully submerged can be manufactured on request (not for continuous operation).
