GRIX is a grinder pump featuring a suction-assisted cutting system that enables the maceration of solids. These pumps are used wherever liquid must be pumped through relatively small-diameter pipes, often already installed. Applications: domestic wastewater, dirty water containing solids, and anywhere high pressure is required.
Characteristics
All main 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-assisted cutting system with a hardened-steel knife in GRIX pumps effectively macerates the contents of domestic wastewater. The knives rotating over a perforated disc act like a meat grinder, cutting everything into small pieces, allowing wastewater to be pumped through narrow pipes with diameters as small as DN40. The adjustable gap makes it possible to control and precisely set the cutting parameters even after the knives have been sharpened repeatedly. The appropriate positioning of the knife openings prevents several items from being cut simultaneously, which prevents the knife from jamming and the pump from failing.
GRIX grinder pump installations
GRIX pumps are designed for small domestic wastewater pumping stations and compact pumping stations often located in buildings. Pumps with a radial solids maceration 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.
Controlling the domestic grinder pump
For controlling GRIX pumps, we recommend M121 or M131 controllers (single- or three-phase), or purchasing the pump 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 to 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, which means they are compatible with coupling feet such as EASY.
