Oliju SGR Submersible Sewage Grinder Pump
Product overview
The Oliju SGR submersible grinder pump provides reliable handling for domestic sewage, wastewater and rainwater containing soft solids or fibres. The stainless steel grinding system breaks down waste before pumping, preventing blockages and ensuring smooth flow through your pipework.
Designed for high head applications, the SGR offers flexible installation options for pumping chambers, operating either freestanding or on guide rails. Single phase models feature an automatic float switch for hassle-free liquid level management.
