Float version
The G2 series (GM-GT two-pole) features a suction-assisted maceration system that enables solids to be ground. These pumps are used wherever liquid must 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 GG25 cast iron. The disc and macerator are made of hardened steel. Two separate mechanical seals (the motor side in the oil chamber and the impeller side in contact with the liquid), together with high-quality components, ensure excellent performance and product reliability.
Why choose a professional GM macerator?
The vacuum knife-cutting system in G2 pumps combines the effectiveness of radial and axial cutting. The truncated-cylinder-shaped cutter rotates between a specially designed inlet, cutting, tearing, and grinding the solids contained in municipal and industrial wastewater as thoroughly as possible. Pieces of rags, strings, or soaked straw are no problem. In addition, the blade can be serviced quickly and easily thanks to hex socket screws, which is a major advantage during pumping-station downtime.
GM macerator pump installations
GM pumps are designed for professional networked wastewater pumping stations and industrial installations (e.g. agriculture, slaughterhouses, etc.). Pumps with an axial-radial solids maceration system can be successfully installed on coupling feet, such as DUTY 50 and B4.
GM macerator pump control
For controlling GM pumps, we recommend professional power and control cabinets in a simple relay-contactor version or a more advanced processor-based version.
FEATURES
• Radial-axial maceration system,
• Hardened steel blades ensure effective cutting of contaminants,
• The oil chamber prevents water from directly entering the motor 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,
• Built-in float controls pump operation and protects 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 up to 60°C with the pump fully submerged are available on request (not for continuous operation).
