Key features and benefits of the GEHO hydraulic driven piston pumps
Initiator: hydraulic cylinder position measurement• Ensuresfulluseofstrokelength,• allowsforelectronicmonitoring• andsoftstopandstart-up due to sensors located at the end ofsuctionanddischargestroke.
Linear transducer: hydraulic cylinder position measurementAllowsathighspeedasoftstopandstart-up–duetoaslenderbarmountedinthepistonrod.
Hydraulic cylinder piston sealNoleakage/higherefficiency,accuratecontrolatlowcapacity–duetouseofstandardhydraulicsealsbecauseofabsenceofboreholes.
Sludge cylinder liner and pistonLongwearlifeofcylinders–dueto0,4mmchromeplating.
Reducedwear,energyconsumptionandlowestfrictionlosses–duetohardchromeplatedandprecisionmachinedliner,allowsforflexiblelipsealandguideringdesign.
Option 1: DHC
Transfer tube

Cone valves• Reducedmaintenancecosts–duetovalve andvalveseatreplacementwithoutdisconnecting piping,hydraulichosesormovingthepump.• Reducedpressurepulsation-duetothevalve openingandclosingsequence,preventsback flowfromdischargetosuction.• Nooilcontamination–duetostuffingbox betweensludgeandhydrauliccylinder.• Quickmaintenance–duetohydraulicvalve seatrelease.
Option 2: DHT
