High-Pressure Plunger Pump
Type
250 ARP®
|
|
|
General Aspects
|
 |
Suitable for the transport of water containing grained
and fibrous solids of different size and shape
|
|
For coarse impurities, a filter in the supply line is
required
|
|
Pump Gear
|
|
Proven pump gear with forced lubrication and integrated
reduction gear, alternative gear ratio available.
|
|
Pump Head
|
|
Pump head with flow optimized valve arrangement
|
|
Large valves with low flow resistance
|
|
Erosion and cavitation resistant materials within the
valve areas
|
|
Minimum pressure fluctuation due to optimized valve kinematics
|
|
High service life of all pump components, also for water
with impurities
|
|
Easy maintenance due to simple assembly and good access
|
|
Additional Equipment
|
|
Pressure regulating valve, manually or pneumatically operated
|
|
Pneumatically operated 2/2-way and 3/2-way, respectively,
switch valve
|
|
The Technique
|
|
All parts attacked by accelerated wear are very easy of
access and can simply be disassembled and reinstalled
|
|
Suction and pressure lines do not need to be released
during disassembly and installation
|
|
Reliable sealing even at abrasive attack due to the elastic
behavior of the needle valve inserts
|
|
Valve seats made from corrosion resistant steel consist
of two precisely manufactured seat surfaces that can be
used twice by tilting
|
|
Working areas of the cylinders can be evacuated under
depressurized conditions due to lifting the valve lifter
|
|
