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.

Detailed dimensional drawings and

weights available on request.
