The JDWm pump is a self priming centrifugal jet pump particularly suitable for pumping from deep wells. A unique feature of the design is that the jet housing can either be installed directly onto the pump body where suction lifts are small (less than 7 m) or unbolted and lowered into the well where it can be used on suction lifts up to 40 m. Operating efficiency is greater with the jet body bolted onto the pump. The pump is designed for pumping clean, chemically non-aggressive liquids in a variety of domestic applications and is well suited for use in conjunction with either a 'Presscontrol' or surge tank to provide automatic operation.
Pump body and ejector assembly are constructed from cast iron and the impeller from brass alloy.
The close coupled fan cooled induction motor is provided with a thermal overload cutout device for motor protection on the 0.75 kW motor. The 1 .1 kW motor requires a standard remote starter.
