HDP 70 High Pressure Pump Series Design criteria Hammelmann high pressure pumps are built to operate at the continuous maximum duty stated in the performance parameters. Just compare the crankshaft speed, average plunger speed, plunger diameter and power rating. High pressure pump Weight: approx. 215 kg Features  Power ratings up to 70 kW  Vertical 3 cylinder design  Wide variety of complementary ancillaries Quality and reliability  Stainless steel pump head free of alternating stress  Bellows form hermetic seal between the suction chamber and crank section Stationary unit with electric motor Length: 1502 mm Width: 720 mm Height: 1105 mm Weight: approx. 1150 kg at 75 kW  Choice of application specific seal assemblies  Solid ceramic or tungsten carbide plungers  Choice of bronze (standard) or stainless steel suction chamber  Crank section calculation by ‘Finite element method’ ensures long working life under continuous load  Integral speed reduction gear Main dimensions without accessories such as suction line, pressure regulator etc. All shown as right side drive. Detailed dimensional drawings and weights available on request.  Pressurised oil lubrication syst
