The Zenit GRE submersible electric grinder pump is ideal for installation in small lifting stations where compact size and excellent reliability are required.
Installation flexibility is ensured by the option of threaded or flanged discharge. These series have hydraulics with grinding system (GRE), which is recommended for soiled liquids containing fibres and filaments. The high heads are suitable for use in mainly clean liquids when high pressure level is required.
The GRE model has an external box with circuit-breaker and current overload protection. This guarantees a reliable operation with soiled liquids (even after idling for a long time), when a high startup torque is required.
Each model undergoes pressurised tests to ensure that the motor compartment is airtight and the mechanical seals are fitted correctly, guaranteeing excellent reliability.
This electric grinder pump contains a cast iron multi-channel open impeller. Special spiral ribs on the rear of the impeller help to tear and eject filaments preventing over loading of the motor.
The grinding system comprises of a three-bladed rotary knife and a plate with holes with sharpened edges that fine-chops filaments, which prevents fouling of the impeller.
Perfect for use in soiled waters that contain fibres and filaments including domestic and other civil wastewater.
