The G2 series (GM-GT two-pole) features a suction-assisted grinding system that can grind solids. These pumps are used wherever liquid needs to be pumped through relatively small-diameter pipes, often those that are already installed. Applications: domestic wastewater, liquids containing solids, and any situation where high pressure is required.
Features
All main components are made of GG25 cast iron. The impeller and grinder are made of hardened steel. Two separate mechanical seals (motor side in the oil chamber, impeller side in contact with the liquid) and high-quality components ensure excellent performance and product reliability.
Why choose a professional GM grinder?
The vacuum cutting system with a hardened steel blade in G2 pumps combines the effectiveness of radial and axial cutting. The truncated cylindrical cutter rotates between a specially designed inlet to cut, tear and grind solids contained in municipal and industrial wastewater as thoroughly as possible. No rags, strings or soaked straw can stop it. What’s more, the blade can be serviced quickly and easily using hex socket screws, a major advantage when a pumping station is down.
GM grinder pump installations
GM pumps are designed for professional municipal wastewater pumping stations and industrial installations (e.g. agriculture, meat processing plants, etc.). Pumps with an axial-radial system for grinding solids can be successfully installed on coupling feet, e.g. type DUTY 50 and B4.
GM grinder pump control
For controlling GM pumps, we recommend professional power and control cabinets, available in a simple relay-contactor configuration or a more advanced version with a processor controller.
FEATURES
• Radial-axial shredding 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 connection for a flexible hose with a clamp or quick coupling,
• 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 for liquid temperatures up to 60°C with the pump fully submerged are available to order (not for continuous operation).
