NTS619 Diesel Fuel Injection Pump Test Bench

When a heavy-duty truck sits idle because of a faulty injection pump, the clock is literally burning money-lost revenue, missed delivery windows, and a service bay that stays blocked for hours. The NTS619 Diesel Fuel Injection Pump Test Bench is built specifically to pull your shop out of that cycle. Instead of sending pumps out for third-party calibration and waiting days for return, you bring the full diagnostic capability in-house. This frequency-conversion test stand handles in-line and distributor-type pumps from Bosch, Denso, Delphi, and Siemens, with a 0–4000 RPM variable-speed drive and selectable power from 7.5kW to 22kW. It supports up to 12 cylinders with 10 preset RPM points for standardized sequences, plus built-in temperature control, positive/negative pressure systems, and onboard air supply-so you stop guessing and start verifying.

The NTS619 delivers the hard numbers your service crew actually works with. RPM pre-set function allows one-touch recall of test speeds, cutting setup time between different pump families. The DC power supply (12V/24V) energizes distributor pump solenoids and electromagnetic actuators directly on the bench, eliminating the need for external power leads. For VE pump overhaul, the stand measures internal pressure and oil return volume simultaneously-two readings that often determine whether a distributor head gets rebuilt or replaced. The rack travel measurement (optional high-precision sensor) gives you digital feedback on governor response, while the optional advance angle module verifies automatic timing mechanisms without mechanical dial gauge guesswork. The 125mm main shaft center height accepts standard fixtures, and bi-directional rotation covers both clockwise and counterclockwise pump configurations across European and Asian platforms.

The NTS619 runs on standard three-phase mains (380V/50Hz or 220V/60Hz available upon request), so you are not rewiring your bay or calling an electrician for specialty power. The 60-liter oil tank with integrated heating maintains consistent viscosity without external oil conditioners. The computerized interface displays speed, temperature, stroke count, rack position, and pressure on a single 15-inch screen, with data logging that generates customer-facing reports-useful when documenting warranty claims or justifying rebuild charges. Optional forced cooling is worth considering if your typical workload includes high-load pumps above 12kW or continuous run-in cycles exceeding 30 minutes; otherwise, the standard thermal management handles most on-highway and off-highway applications. 

The NTS619 reduces the two biggest hidden costs in diesel pump repair: inventory buffer and come-back labor. Testing returned pumps on-site means you decide immediately whether to rebuild, exchange, or scrap-no more holding multiple exchange units while waiting for external test reports. The integrated pressure systems allow you to verify pump body sealing before assembly, catching porous castings or worn shaft seals that would otherwise leak after installation. The ability to measure VE pump internal pressure across multiple speeds helps you identify distributor head wear that reduces high-speed delivery, a common failure mode that leads to low-power complaints. By confirming governor cut-off speeds and rack travel digitally, you eliminate the subjective feel of mechanical gauges, so every pump leaves your bench with documented traceability. 

Q1: What is the typical lead time for a 5-unit bulk order to North America or Europe?
A: Production lead time is 20–25 working days after PO confirmation. For consolidated sea freight, we recommend ordering 8–10 weeks before your peak season to secure container space and avoid air freight surcharges.

Q2: How does the bench hold up with high-mileage VE pumps that have internal scoring?
A: The internal pressure reading and oil return volume will show elevated leakage values-this allows you to quantify wear and decide whether a distributor head rebuild is viable or if replacement is more cost-effective over the next 200,000 km.

Q3: Can our technicians use the test data to support warranty disputes with parts suppliers?
A: Yes. The system generates time-stamped reports with speed, temperature, per-cylinder delivery, and advance angle. Many shops use these printouts as formal evidence when OEM suppliers question premature pump failures.

Q4: What maintenance does the stand require for a shop running 8–10 tests daily?
A: Replace test oil and clean the filter every 200 operating hours. Verify calibration using reference nozzles or a master pump quarterly. The frequency-conversion drive and main bearings routinely exceed 8,000 service hours under scheduled maintenance.

Q5: Is the optional forced cooling necessary if our shop has air conditioning?
A: If you regularly test pumps above 12kW output or run endurance cycles longer than 30 minutes, forced cooling prevents oil temperature from rising beyond the 40±2°C window. Shop AC alone cannot compensate for heat generated during high-load pump testing.

Q6: Do you provide fixture adapters for older Bosch P-series and Denso distributor pumps?
A: The NTS619 accepts standard mounting fixtures. We can supply additional adapter sets for less common pump foot patterns upon request-please confirm your pump family list when ordering.
