Frequently Asked Questions
What power source is needed to drive the Interpump W112 pump?
The Interpump W112 requires a minimum 3 HP (2.2 kW) electric motor or equivalent petrol engine drive setup operating at 1450 RPM.
What is the benefit of a low-speed 1450 RPM pump?
Running at 1450 RPM reduces heat build-up and mechanical wear on ceramic plungers, oil seals, and valves compared to high-speed 2800 RPM pumps, significantly lengthening service intervals.
Can I order the Interpump W112 with a brass pump head instead of aluminium?
Yes. While the standard version comes with a nickel-plated aluminium manifold, a brass head option is available on request.
What are the plumbing connection sizes on the Interpump W112?
The pump features a 1/2″ BSP female inlet thread for supply water plumbing and a 3/8″ BSP female outlet thread for high-pressure hose connections.
