Description
The JS Pumps JS-250 110v Manual heavy duty contractor pump (code 011-202) is a cast iron submersible drainage pump for clean and dirty water. It delivers up to 200 litres per minute and lifts to a maximum head of 10 metres from a 0.25 kW motor, through a 1½” outlet, running on 110v, the reduced-voltage supply used on UK construction sites through a site transformer.
This is the manual version, so it runs whenever the power is on. That suits attended dewatering, or a fixed installation where a separate float switch or control panel switches the pump. The JS-250 110v Automatic is the same pump with automatic operation, and the JS-400 110v Manual is the next size up, 240 l/min to 12 m.
Like every pump in the range, it has a stainless steel motor case and shaft, a cast iron volute, motor top cover and lower bearing and seal housing, and twin mechanical seals (carbon ceramic and silicon carbide) in a lubricated oil chamber. The side-mounted outlet points vertically upwards, and the pump comes with 10 metres of power cable and a hose tail.
