Float version
The GX macerator pump has a suction cutting system that can macerate solids. These pumps are used wherever dirty liquid needs to be pumped through relatively small-diameter pipes, often already installed. Applications: domestic wastewater, liquids containing solids, and any situation requiring high pressure.
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 macerator pump - Advantages
The GX pumps’ vacuum-based axial cutting system with a hardened steel blade effectively macerates 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 cutting 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 macerator pump installations
GX pumps are designed for domestic wastewater pumping stations and compact pumping stations, often located inside buildings. Pumps with an axial solids macerating system can be successfully installed on coupling feet, e.g. type EASY 3.1 or EASY 3.2, in DRENO BOX pumping stations, or on DUTY 50 coupling feet.
Controlling a domestic grinder pump
GX series pumps can be controlled either by the 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 tailored to the customer's requirements.
FEATURES
• Axial macerating 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,
• Side flanged outlet with an additional thread allows installation on a coupling foot and easy installation of an elbow connector for a flexible hose secured with a clamp or quick coupling,
• Built-in float switch that controls pump operation and protects it against dry running,
• Built-in T1-T2 thermal protection in the motor winding, connected to a dedicated control panel,
• 10 m H07RNF power cable terminated in a starter box,
• Warranty and post-warranty service,
• 24-month warranty.
Special versions capable of handling liquid temperatures up to 60°C with the pump fully submerged are available to order (not for continuous operation).
