GRIX is a grinder pump featuring a suction-assisted cutting system that enables the shredding 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, dirty water containing solids, and anywhere high pressure is required.
Features
All major components are made of GG25 cast iron. 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.
Advantages of GRIX grinder pumps
The vacuum knife-cutting system made of hardened steel in GRIX pumps ensures effective shredding of domestic wastewater contents. Rotating over a perforated disc, the knives act like a meat grinder, cutting everything into small pieces, which makes it possible to pump wastewater through narrow pipes with diameters as small as DN40. The adjustable gap allows the cutting parameters to be controlled and precisely set even after the knives have been sharpened repeatedly. The appropriate positioning of the knife openings prevents several items from being cut simultaneously, which avoids knife blockages and pump failures.
GRIX grinder pump installations
GRIX pumps are designed for small domestic wastewater pumping stations and compact pumping stations often located inside buildings. Pumps with a radial 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 a domestic grinder pump
For controlling GRIX pumps, we recommend M121 or M131 controllers (single- or three-phase), or purchasing the pump in a version with a built-in control float. For more demanding customers, we can offer advanced control systems, for example with 3, 4, or 5 floats, a hydrostatic probe, or alarm signal outputs on a terminal strip, enabling connection to an external monitoring system.
Like every DRENO wastewater pump, it comes standard with a 10-meter power cable. All GRIX pumps have a side outlet, making them compatible with coupling feet such as the EASY type.
