High-Pressure Plunger Pump
Type
550 ARP®
|
|
|
General Aspects
|
 |
Suitable for pumping water containing grained and fibrous
solids of different size and geometrical shape
|
|
For coarse impurities, the application ofa 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 area
|
|
Optimized valve kinematics giving minimum pressure fluctuation
|
|
High service life of all pump head components, also for
water with impurities
|
|
Easy maintenance due to simple assembly and good access
|
|
Additional Equipment
|
|
Manually or pneumatically operated pressure regulation
valve
|
|
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 removed and reinstalled
|
|
The suction and pressure pipes which are difficult of
access do not need to be released
|
|
A reliable sealing even at abrasive attack is due to the
elastic behavior of the inserts on the needle valve taps
|
|
The valve seats made from corrosion resistant steel consist
of two precisely manufactured seat surfaces which can be
used twice by tilting
|
|
The working areas of the cylinders can be evacuated under
depressurized conditions due to lifting the valve lifter
|
|
