1 high pressure technology that sets the standardHigh pressure pumpsUltra high pressurepumpsPump unitsQuality The most modern developmenttechniques Analysis areused during the design phase toachieve optimal component configuration. Our computer controlled workshop ensures constant dimensional components andproducts are subjected to stringentquality control procedures. Allpumps, pump units and accessoriesare tested under maximum load in our modern test facility works in accordancewith and is certified to the DIN ENISO 9001 quality management qualityA clean medium is an advantage forall high pressure pumps.

2 Abrasivematerials in the water will shorten thelifetime of valves, valve seats andwater jetting tools. An advantage ofthe dynamic plunger seal with labyrinth insert is that each stroke ofthe plunger washes away pump configurationOur three and five cylinder highpressure pumps are mounted verti-cally. This offers certain advantages: The crosshead and plungerweights are neutralised within thesealing system, effectively reducingwear on all oscillating components. Automatic air venting is ensuredwhich greatly decreases the possibility of cavitation.

3 Enables construction of very compact units with all importantcomponents accessible from allaround the pump. This simplifiesmaintenance works. The ability to position the pumpcompletely within the frameworkreduces the width of units furtherenhancing compactness. Linearly aligned forces of gravitybetween the pump and the dieselengine reduce Analysis of HDP 230 crankshaftHigh and ultra high pressure pumpsWater supplyA complete water supply systemcomprises header tank, boost pumpand fine filter to compensate thevarying on site supply water and bypass water arereturned to the header tank.

4 Advan-tages: lower water consumption,drainage lines are header tank, boost pump and bypass line are all made fromnonrusting ancillary components Boost pumpThe boost pump in combination withthe header tank ensures that optimaloperating conditions exist for the high pressure pump. Theboosters are belt driven on dieselpowered units and by independentE-motor on electrically status monitoringMonitoring water and oil pressuresprevents possible pump damage bycavitation or lack of oil.

5 Operating pressure and drivemotor/engine condition can also be monitored. The unit shuts downimmediately preset limits are speed regulation for dieselpowered unitsWhen the required working pressureis entered into the control computerthe engine speed will automaticallyadjust to achieve it. When the pumpor jetting tool switches to bypass theengine speed automatically drops toidling. This cuts down wear andsaves on fuel reels Manual or hydraulically poweredhose reels store hose neatly andease the work on site.

7 Built into containers. Dueto its compactness even a 5 cylinderhigh pressure pump with a 310 HPdiesel engine will fit neatly into a 10 ft. section The crank sections calculationsare made employing the Finiteelement method resulting in desi-gns that ensure a long working lifeunder continuous load. An integral speed reducer usingtwin helical gears arranged inherringbone configuration ensuressmooth running and even powertransmission without axial load tothe bearings. A selection of gearratios is available to allow theoptimal choice of driver.

8 Low noise , compact crank sections built for continuous duty Conversion kitsAll Hammelmann high and ultra highpressure pumps can be convertedwith ease to different pressure /flowrate combinations. The high reliability forged crank-shaft is supported by bearingslocated between the connectingrods so that the bearing load isspread lubricationsystem All moving parts are subjected toforce fed lubrication. The pressurised circulating oillubrication system protects thehigh pressure pump even underextreme operating conditions suchas inclined working, continualchanges in demand and very highor very low ambient/medium tem-peratures.

An integral oil cooler regulating valvesManually or pneumatically actuatedpressure regulating and bypassvalves set the maximum operatingpressure and enable the use of dryshut off valves in the pressure switched to bypass the medium flows without pressure towaste or to of an eccentric lever onmanually actuated valves results inimmediate pressure relief which is asubstantial safety controlledvalves can be fitted with a solenoidto automate the bypass design - minimal components - high

10 ReliabilityPump head The pump head with antechamberis designed for high reliability. Theminimal number of components,especially seals, are clear evidenceof this. The valve housing is not subjectedto alternating stress. This specialdesign eliminates the risk of fatiguecracking and keeps pressureloaded surfaces to an absoluteminimum resulting in a correspon-dingly reduced force. Parts subjected to constant loa-ding and unloading are rotationallysymmetrical and have surfacestreated to prevent metal life and reliability are featuresof Hammelmann pump systemsThe sealing systems can be mat-ched to differing pumping duties.
