Cummins engine spare parts Measurement pump assembly A060H209

Equipped with a servo-driven piston mechanism and a high-resolution Hall-effect sensor, the measurement pump delivers exceptional metering accuracy: controlling fuel flow rates from 0.5 to 5 L/min with a tolerance of ±1%—critical for maintaining the precise air-fuel ratio required for Cummins engines to meet EPA Tier 4 Final and Euro VI emission standards. The pump’s piston stroke is electronically adjustable (via ECU signals) in 0.01mm increments, enabling real-time flow optimization based on engine load (e.g., increasing flow during heavy acceleration, reducing flow at idle). It updates flow rate data every 50 milliseconds, ensuring the ECU can respond instantly to changing operating conditions—improving fuel efficiency by 2–3% compared to imprecise aftermarket pumps and reducing exhaust emissions (NOx and particulate matter) by up to 15%

Engineered to withstand the harsh conditions of engine fuel systems (exposure to diesel fuel, temperature fluctuations, and vibration), the pump features a durable, corrosion-resistant design:

Housing: Die-cast aluminum alloy housing (ADC12 grade) with an anodized surface treatment, resisting corrosion from diesel fuel additives (e.g., biodiesel blends) and preventing fuel leakage (tested to 10 bar pressure for 24 hours with no seepage).

Piston & Seals: A stainless steel piston (304 grade) with a PTFE-coated surface (reducing friction) and nitrile rubber seals (resisting fuel swelling), ensuring reliable operation even with low-quality diesel fuel (up to 500 ppm sulfur content).

Electrical Components: A sealed electrical connector (IP67 rating) and moisture-resistant circuit board (conformal coating), protecting internal electronics from fuel spray and engine bay humidity—ensuring functionality in temperatures ranging from -40°C to 120°C

To safeguard the pump and engine fuel system from damage, the assembly integrates multiple safety and diagnostic mechanisms:

Overpressure Protection: A built-in relief valve that opens when fuel pressure exceeds 15 bar (e.g., due to a clogged fuel line), preventing pump housing rupture or piston damage.

Low-Fuel Detection: A flow sensor that triggers an ECU warning if fuel flow drops below 0.3 L/min (indicating a fuel supply issue), preventing engine starvation and potential damage.

Self-Diagnostic Function: The pump transmits real-time performance data (flow rate, pressure, temperature) to the ECU, which can identify faults (e.g., sensor failure, piston sticking) and store error codes for easy troubleshooting—reducing maintenance time by 40% compared to non-diagnostic pumps

Designed for efficient replacement by engine technicians, the measurement pump simplifies installation and reduces downtime with user-friendly features:

Direct Wiring & Plumbing: The 4-pin connector matches the engine’s factory wiring harness (color-coded for error-free connection), and the 12mm inlet/outlet ports use standard fuel line quick-connect fittings—no cutting, flaring, or soldering required.

No Calibration Needed: As an OEM component, the pump is pre-calibrated to Cummins’ specifications, so it works immediately after installation without the need for ECU reflashing or flow rate adjustment.

Long Service Interval: The pump’s wear-resistant components (stainless steel piston, PTFE coating) enable a service life of 200,000 km (equivalent to 8,000 operating hours) with no maintenance beyond regular fuel filter replacement.

Installation takes 30–45 minutes: disconnect the fuel lines and electrical connector from the old pump, unbolt the mounting flange (using a 10mm socket), install the new pump, reconnect the lines and connector, and prime the fuel system. Each unit undergoes 100% performance testing (flow accuracy, pressure resistance, electrical function) and quality inspection, backed by a 24-month OEM warranty against defects (e.g., leakage, sensor failure, flow inaccuracy)
