Fiat Tractor Hydraulic Gear Pump Replacement – 11ml 160bar

GBC-FIAT-11ML — Fiat Tractor Hydraulic Gear Pump Replacement – 11ml 160bar

This external gear pump is a Fiat-series replacement unit identified by Manufactory Reference FIAT. It carries no OEM cross-reference numbers but is characterised by its 11.0 ml/r displacement, 160 bar maximum pressure, and identical 13.6 mm bore inlet and outlet ports — an unusual configuration in which feed and discharge port sizes are the same. The pump has clockwise (right-hand) shaft rotation and a speed range of 500–3,000 r/min. It is used on certain Fiat tractor models where standard OEM reference matching is not available and identification must be made by physical measurement.

The GBC-FIAT-11ML is designed for buyers who have measured and confirmed their existing pump matches this specification — 11 ml/r, 160 bar, 13.6 mm equal-bore ports, right-hand rotation. It is particularly relevant for older Fiat models or export/variant machines where parts documentation is incomplete. For the complete GBC tractor hydraulic pump range, visit the GBC homepage.

MOQ: flexible. Minimum order value USD 1,500; mixed orders and trial quantities welcome.

OEM Reference Numbers and Fitment

No OEM part numbers are listed for this pump. Identification must be made by physical measurement. Confirm: (1) pump body displacement is 11.0 ml/r (measured or stated on nameplate); (2) inlet and outlet ports are both Φ13.6 mm bore (equal diameter); (3) shaft rotation is clockwise when viewed from the drive end; (4) maximum system pressure is 160 bar or below. If all four criteria match, the GBC-FIAT-11ML is the correct replacement. Contact our team with your pump measurements if you need fitment confirmation before ordering.

Technical Specifications

When OEM References Are Unavailable

For some older or export-market Fiat tractor variants, OEM part documentation is incomplete or contradictory. In these cases, the most reliable identification method is direct physical measurement of the existing pump. Key measurements to take: (1) gear set displacement in ml/r — this can be calculated from flow rate and speed if a test bench is available, or read from a nameplate if present; (2) port bore diameters — measure the internal diameter of the inlet and outlet ports or the OD of the fittings that thread into them; (3) shaft diameter and keyway dimensions; (4) mounting bolt pattern centre distances.

For the GBC-FIAT-11ML, the key identifiers are the equal 13.6 mm bore on both ports and the 11 ml/r displacement. If your pump matches these and is right-hand rotation, this is your replacement. Send us your measurements and we can confirm compatibility before you order.

Equal-Bore Inlet and Outlet Ports

Most gear pumps use different bore sizes for inlet and outlet ports — a larger inlet to reduce suction cavitation risk and a smaller, higher-pressure outlet. The GBC-FIAT-11ML is notable for having equal-bore (Φ13.6 mm) ports on both sides. This is the original OEM specification for this Fiat pump application and should not be interpreted as a defect. When reconnecting hydraulic hoses, ensure you connect inlet and outlet correctly — reverse connection will cause the pump to run backwards, destroying the shaft seal and generating no useful flow.

Mark your hoses before disconnecting the old pump so there is no confusion during installation. The high-pressure discharge line is typically routed to the hydraulic control valve, while the low-pressure inlet comes from the reservoir or filter outlet. Contact us if you need guidance.

Supply Information

GBC maintains stock of this pump for buyers who have confirmed the specification by measurement. Because there is no OEM reference number for cross-referencing, we recommend buyers confirm their measurements in writing before placing an order. We can supply a dimensional drawing on request.

Contact our team with your pump measurements — displacement, port bores, shaft diameter, mounting hole pattern — and we will confirm the GBC-FIAT-11ML is the correct replacement before processing your order.
