HD 8/18-4 M PU middle-class pump unit with robust 3-piston axial pump with brass cylinder head and 4-pole slow-running three-phase motor. Suitable for horizontal and vertical operation.
Our powerful HD 8/18-4 M PU motor/pump unit with robust 3-piston axial pump and brass cylinder head, 4-pole slow-running three-phase motor and pressure switch control impresses with up to 20% higher energy efficiency and cleaning performance. The stationary middle-class machine is designed both for vertical and horizontal use. The 3-point support on the back of the machine enables vertical wall mounting as well as horizontal installation. Easy access to the high-pressure pump, which is protected by a large water filter, and to the electronic components, is proof of the extremely maintenance-friendly machine design. Using the Servo Control function, the water volume and working pressure can be varied by selecting the corresponding nozzles. All high-pressure components are protected from loads in stand-by operation by the reliable automatic pressure relief feature.
