Product Description
The Davey D150GA is a heavy-duty submersible grinder sewage pump with an automatic float switch, designed for grey and black water pumping, sump emptying, septic effluent and sewage disposal, and wastewater containing soft solids in suspension.
The D150GA features a heavy-duty shredding and grinding ring at the inlet that reduces soft organic solids, sanitary products, thin rubber products and some textiles into a slurry for pumping. Its centrifugal open impeller helps prevent blockage by small solids in the slurry, while its high-head design allows connection to smaller discharge pipe systems and is particularly suited to pumping wastewater to pressure sewer mains.
Powered by a 1.5kW single-phase motor, the D150GA features a cast iron impeller and pump casing, high chromium steel shredding and grinding rings, and a 304 stainless steel pump shaft and motor shell. Double mechanical shaft seals operate in a captive oil bath, with a silicon carbide/ceramic seal on the pump side, while a seal sensor lead allows connection to a protection relay for early detection of seal leakage. The automatic float switch starts and stops the pump as the water level rises and falls.
