The 919/75002 hydraulic gear pump is a OEM-quality hydraulic gear pump for JCB machinery, supplied by Olive Branch Hydraulics from our factory in Hebei, China, on EXW Hebei terms. The reference is also searched as 91975002 and 919-75002, and we confirm fitment against your machine PIN/serial and the original part number before quoting.
Original-equipment quality (原厂原装品质), supplied under the Olive Branch Hydraulics brand. Confirm the pump specification and machine application before ordering.
Our catalogue confirms the reference 919/75002, the product type (hydraulic gear pump) and the front, inlet, outlet and side appearance of the unit. Every other dimension is matched to data you supply or to a drawing we both sign off.
Reference formats covered: 919/75002, 91975002, 919-75002.
Other search terms: bomba hidráulica 91975002, pompe hydraulique 91975002, гидронасос 91975002.
Supply basis: manufacturer, EXW Hebei, with trial orders and pre-shipment inspection available.
Build details are fixed only after your sample or drawing is confirmed.
Matched to a confirmed drawing: Shaft, flange, port positions and body length are built to a drawing approved by both sides. Nothing goes into production on catalogue appearance alone.
Custom shaft options: Spline, keyed or tapered shafts are made to the tooth count, diameter and length taken from your original pump. Check shaft engagement before installation.
Flange and port configuration: Mounting flange pattern, pilot diameter and inlet/outlet thread type are reproduced from your data. Port sizes and positions are compared against the inlet and outlet views in our catalogue.
Rotation set per order: Gear pumps are typically single-direction, so rotation is built to the direction you confirm from the original unit. Confirm rotation before starting; incorrect rotation can damage the pump.
Pre-shipment inspection: Each order is inspected against the agreed drawing before dispatch. Order-specific inspection records are shared only when they exist for that order.
See the specification review above. Dimensions and operating ratings are confirmed against your original pump, part number and approved drawing.
Check the following six items before confirming a OEM-quality pump.
Machine PIN and model: Read the PIN/serial from the machine plate and note the exact model; pump specifications can change within one model range.
Original part number: Copy the number stamped or tagged on the old pump; we do not assume equivalence between superseded or cross-referenced numbers.
Shaft: Record shaft type, outside diameter, spline tooth count and protruding length.
Flange: Measure bolt-hole centres, pilot diameter and the number of mounting bolts.
Ports and rotation: Photograph inlet and outlet ports, note thread type, and read the rotation arrow on the body.
Duty: State the circuit the pump feeds (main, steering or auxiliary) and typical working hours.
Have the old pump on the bench?: Photos of the front, side, inlet and outlet plus the machine PIN are enough for our engineers to start the fitment check.
Custom work is quoted against a drawing, not a catalogue picture.
Built to your specification for distributor ranges or equipment builders using the 919/75002 footprint.
Your brand label, carton print and part-number labels; labelling and packaging requirements are confirmed before ordering.
A sample is built to the confirmed drawing for fit testing on your machine before volume orders.
Specification review: You send drawing, sample or measurements; our engineers return any open questions.
Drawing confirmation: Both sides sign off the drawing that production will follow.
Sample: A sample is built and shipped for your fit check.
Trial order: A small first batch confirms consistency before larger orders.
Production and inspection: Volume orders are inspected against the approved drawing before EXW release.
Distributors receive tiered pricing quoted by quantity band.
