Professional PT101 Cummins PT Fuel Pump Test Bench and Calibration Stand

Cummins PT Fuel System Platform

The PT test bench is purpose-built for Cummins PT (Pressure-Time) fuel injection systems used in heavy-duty diesel engines. The PT type system uses a mechanical governor with fuel pressure and injection timing controlled by the rotary throttling action of the PT pump. Supported engine families include Cummins N14 / NTA855 / M11 / ISM / ISX / QSX / QSK / K19 / K38 / K50, and Cummins STC (Step Timing Control) / PT(K) / PT(G) / PT(GC) / PT(FCP) fuel systems.

PT Pump Calibration and Injector Testing Functions

The platform provides high-precision pressure measurement, flow rate analysis and air leakage detection for Cummins PT pumps and injectors. Calibration profiles cover idle speed, rated speed, full load and torque curve. Integrated mechanical governor testing allows verification of throttle shaft operation, idle spring tension and transfer pressure.

FAQ — Frequently Asked Questions

Q1. What Cummins engine families are supported?
A: Cummins N14 / NTA855 / M11 / ISM / ISX / QSX / QSK / K19 / K38 / K50 and STC / PT(K) / PT(G) / PT(GC) / PT(FCP) fuel systems.

Q2. Does the platform test PT injectors?
A: Yes. PT injector leakage, opening pressure and injection quantity are tested with high precision.

Q3. Is mechanical governor testing included?
A: Yes. Throttle shaft operation, idle spring tension and transfer pressure calibration are integrated.

Q4. What is the operating voltage?
A: Standard 380V three-phase industrial power with optional 220V single-phase for small workshops.

Q5. Is the platform suitable for heavy-duty diesel service centers?
A: Yes. The industrial-grade design supports continuous commercial operation for mining, marine and heavy-truck service centers.

Supported Cummins PT Pump and Injector Applications

The Cummins PT test platform covers PT (pressure-time) fuel injection systems for Cummins NH / NT / NTC / NTA 855 series, KTA19 / KTA38 / KTA50 marine and industrial engines, and PT(K) type injectors for diesel generator sets. Representative OEM references include Cummins 3047978 / 3054218 / 3054220 / 3067264 PT injectors, Cummins 3042524 / 3047974 PT fuel pumps, and Cummins 3801477 / 3802658 PT(K) injectors.

PT Pressure-Time Calibration and Leakage Test

The platform performs PT injector opening pressure calibration, injection quantity calibration under rated speed and load, leakage / sealing tests at idle and high-pressure conditions, and return-flow measurement for PT type fuel injection systems without engine dismount.
