GRIX is a grinder pump with a suction-powered cutting system that grinds solids. These pumps are used wherever liquid needs to be pumped through relatively narrow pipes, often ones that are already installed. Applications: domestic wastewater, dirty water containing solids, and any situation requiring high pressure.
Features
All major components are made of GG25 cast iron. Two separate mechanical seals (motor side in the oil chamber, impeller side in contact with the liquid), together with high-quality parts, ensure excellent performance and product reliability.
Advantages of GRIX grinder pumps
The suction-powered cutting system in GRIX pumps uses hardened steel blades to effectively grind household wastewater solids. The blades rotate against a perforated disc like a meat grinder, cutting everything into small pieces so wastewater can be pumped through narrow pipes as small as DN40. The adjustable gap lets you control and precisely set the cutting parameters, even after the blades have been sharpened multiple times. The holes are positioned so the blades cannot cut several objects at once, preventing blade jams and pump failures.
GRIX grinder pump installations
GRIX pumps are designed for small residential sewage pumping stations and compact pumping stations often located in buildings. Pumps with a radial solids-grinding system can be successfully installed on coupling feet, such as the EASY 3.1 or EASY 3.2, in DRENO BOX pumping stations, or on DUTY 50 coupling feet.
Controlling a residential grinder pump
We recommend M121 or M131 controllers (single- or three-phase) for controlling GRIX pumps, or purchasing a pump with a built-in float switch. For customers with more demanding requirements, we can offer advanced control systems, for example with 3, 4, or 5 float switches, a hydrostatic probe, or alarm signals routed to a terminal strip to enable connection to an external monitoring system.
Like every DRENO sewage 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.
