High pressure pump 380

HDP 380 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. 1700 kg

Features

 Power ratings up to 380 kW

 Vertical 3 cylinder design

 Wide variety of complementary

ancillaries

Quality and reliability

 Stainless steel pump head free of

alternating stress

 Cross head piston bellows seal

 Choice of application specific seal

assemblies

 Solid ceramic or tungsten carbide

plungers

 Choice of bronze or stainless steel

suction chamber

 Crank section calculation by

‘Finite element method’ ensures

long working life under continuous

load

 Crankshaft supported by 2

bearings and incorporating twin

helical speed reducing gears

 Pressurised oil lubrication system

with oil cooler/filter
