Diaphragm Fuel Lift Pump for Cummins and Case IH Engines - Code 38002493

The heavy-duty mechanical diaphragm fuel lift pump (Product Code: 38002493) is a precision-engineered structural ricambio designed to secure a continuous, stable fuel flow toward the primary high-pressure injection circuit. Developed specifically for mid-to-high displacement industrial internal combustion engines and heavy-duty agricultural machinery, this lift pump maintains constant pressure stability. By preventing priming drops, it secures unhindered fuel feed distribution and safeguards drivetrain reliability under challenging open-field workloads.
Design Details and Geometric Dimensions
This low-pressure mechanical transfer pump features a high-density alloy housing built to withstand substantial structural load parameters and resist hydrocarbon corrosion inside the engine bay. The installation layout incorporates a standardized 2-hole mounting flange configured to secure perfect, vibration-free alignment on the engine monobloc. The center-to-center interaxis distance between the anchoring holes is precisely 45 mm, while the longitudinal extension of the mechanical actuator lever—measured straight from the mounting flange face to the terminal tip of the plunger spintore—reaches 57 mm. The fluid interface is machined with robust 1/4" - 18 NPTF threaded ports to secure stable, leak-free line couplings. Its internal diaphragm matrix is composed of advanced high-elasticity elastomers that retain material memory, preventing premature structural splitting caused by severe thermal cycles.
