This is the MH series 3/6 all stainless steel water pressure pump suitable for domestic, commercial and industrial applications where clean water needs to be supplied at an even and stable pressure. This pump will supply 40 L/minute at 540 kPa which is a high pressure work horse capable of 60 L/min @ 400 kPa which is a large house with 2 or 3 bathrooms and multiple levels. We couple the Italian made pump to a very reliable electronic controller with an adjustable turn on pressure point, the controller provides run-dry protection which means that if the water supply to the pump runs out, the controller will automatically turn off the pump and prevent damage to the pump. When you turn the tap on, the controller senses this and starts the pump, the pump remains on providing pressure until you turn the tap off and then the controller stops the pump, no more annoying pressure fluctuations. 1 1/4" female BSP inlet and 1" male BSP outlet on the controller.
