The G2 Series (GM-GT bipolar) features a suction-based maceration system that enables the grinding of solids. 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 major components are made of GG25 cast iron. The plate 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 the professional GT macerator?
The vacuum knife-cutting system in G2 pumps, using a hardened-steel blade, combines the effectiveness of radial and axial cutting. The truncated-cylinder-shaped cutter rotates between a specially designed inlet to cut, tear, and grind the solids contained in municipal and industrial wastewater as thoroughly as possible. Pieces of rags, cords, or soaked straw are no problem for it. In addition, the blade can be serviced quickly and easily thanks to the hex socket screws, which is a major advantage during pumping-station downtime.
GT macerator pump installations
GT pumps are designed for professional wastewater pumping stations connected to mains networks and for industrial installations (e.g. agriculture, slaughterhouses, etc.). Pumps with an axial-radial solids-grinding system can be successfully installed on coupling feet, such as the DUTY 50 and B4.
GT macerator pump control
For controlling GT pumps, we recommend professional power and control cabinets in a simple relay-and-contactor configuration or a more advanced processor-controlled version.
FEATURES
• Radial-axial maceration 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 using a hose clamp or quick coupling,
• T1-T2 thermal protection built into the motor winding, connected to a special control panel,
• 10 m H07RNF power cable with free terminals,
• 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 to order (not for continuous operation).
