Product Description

The Dayliff DDJ 750 is a centrifugal jet type domestic water pump designed for small‑scale domestic and light commercial water supply needs where reliable self‑priming and good suction performance are required. It features an integral ejector that improves suction lift performance and efficiency. The pump body is solidly built from cast iron, and the ejector and impeller are made from engineering plastic. It is close‑coupled to a TEFC electric motor with thermal overload protection, making it suitable for continuous operation in typical household water systems.
