The Dayliff DWH range of submersible drainage pumps are of robust design for higher head duties in harsh conditions as found in civil engineering and construction sites, mines, quarries etc. Pumps are provided with twin Chrome alloy open impellers for free particle passage, heavy-duty cast iron pump body and motor casing and stainless steel strainer with a mechanical seal and NBR oil seal. The top discharge outlet provides excellent motor cooling due to the jacketed motor arrangement enabling the pump to operate semi submerged. Pumps are designed for free standing installation and are fitted with seal pressure relief ports to prevent the pumping pressure from applying to the shaft seal. All pumps are supplied with 20m of H07RNF cable.
