High-pressure cleaner HD 8/18-4 M St

Mid-class pump unit HD 8/18-4 M St with 3-piston axial pump with brass cylinder head and 4-pole, slow-running three-phase motor. Can be used horizontally and vertically.

The motor/pump unit HD 8/18-4 M St comprises a 3-piston axial pump with a brass cylinder head, a 4-pole three-phase motor and pressure switch control. The device is designed for vertical and horizontal operation. A 3-point mount on the back of the device enables vertical wall mounting or horizontal installation. The high-pressure pump and electronic components are accessible; a water filter is installed. The Servo-Control function enables the adjustment of water volume and working pressure. Automatic pressure relief protects the high-pressure components in stand-by operation.
