HDP 20 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 crank shaft speed, average plunger speed, plunger diameter and power rating. High Pressure Pump Weight: 95 kg Features • Power ratings up to 18,5 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 • 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 • Pressurised oil lubrication system • Separate oil pump Stationary unit with electric motor Length: 1000 mm Width: 752 mm Height: 890 mm Weight: approx. 450 kg at 22 kW Main dimensions without accessories such as suction line, pressure regulator etc. All shown as right side drive.
