System compatibility

109-0785-4B14-09 belongs to Rexroth hydraulic gear pump series,matched with pump housing,shaft seal and hydraulic power unit.Widely applied in press equipment,automation assembly and material handling hydraulic stations.This is a discontinued legacy spare part for equipment maintenance replacement.

Function

109-0785-4B14-09 is Rexroth internal gear pump cartridge.It forms the core pumping assembly of gear pump,delivers hydraulic oil from suction port to pressure outlet.It provides stable flow for downstream hydraulic actuators under rated working pressure.It maintains volumetric efficiency during continuous operation.It acts as hydraulic power generating core component of hydraulic pump.

Installation

Insert 109-0785-4B14-09 into pump housing,align shaft and positioning pin.Install sealing components and tighten end cover bolts.Check oil circuit cleanliness and seal integrity before commissioning.

Interface

‑Driving shaft connection end

‑Suction oil passage matching port

‑Pressure oil passage matching port

‑Positioning pin hole

Circuit feature

Precision gear pair machining,low internal leakage design,stable flow output under industrial hydraulic working environment.

Feature

109-0785-4B14-09 is obsolete Rexroth spare part.Typical faults:flow insufficient,pressure drop,internal leakage,gear wear and noise.Inspect gear surface and sealing parts before replacement.This cartridge must match corresponding pump housing and working pressure,direct substitution without inspection is not recommended.

Diagnostic

When gear abrasion,seal failure or contamination jam occurs,the system will report hydraulic pressure and flow abnormal alarm.

Built‑in function:Hydraulic oil suction and delivery,continuous fluid power output,used as hydraulic pump system spare replacement.

Product Brief

109-0785-4B14-09 is Rexroth old gear pump cartridge for hydraulic power station.Confirm working pressure and hydraulic oil medium before ordering.ESD protection required during handling and installation.
