The stand-alone pump unit out of the HD Middle class is the perfect solution for integrated high-pressure pumps e.g. stationary machine and production progress. A reliable high-pressure pump which is protected by a robust plastic chassis and not more. The machine is intended for stationary use and can be mounted and operated both horizontally and vertically. A 3-point support on the back enables vertical or horizontal mounting. Access to the high-pressure pump and the electronic components is easy and therefore service-friendly – the pump itself is effectively protected from dirt in reclaim water by means of a large water fine filter.
