CR3000A-708 High-Pressure Common Rail Test Bench

For a diesel repair shop, every hour a bay sits idle eats directly into margins. The CR3000A-708 was built to cut that downtime-not by listing features, but by giving you a single platform that handles nearly everything that rolls through your doors, from mechanical inline pumps to the latest piezoelectric injectors.

When a truck is down, the diagnosis chain often breaks at the test bench. The CR3000A-708 changes that. It drives a BOSCH CP3.3 pump and uses a BOSCH DRV valve to push rail pressure up to 2800 bar, holding accuracy at ±0.5 bar. That precision matters less as a spec sheet number and more as a guarantee: you won't waste hours chasing a pressure drift that turns out to be a sensor reading error. The flow sensor reads from 0.008 to 4L/min at 0.3% accuracy -tight enough to catch injector degradation before it causes a comeback, loose enough to handle high-flow pump testing without maxing out.

Motor options range from 7.5KW to 22KW with 220V/380V three-phase support, and the drive covers 0–4000 RPM. That flexibility means a shop working mostly on highway tractors can spec a higher-torque motor, while a light-duty specialist keeps costs down with a smaller unit. Oil temperature holds at 40±2°C with air or forced cooling-a detail that prevents viscosity shifts from skewing flow readings during long test cycles. The embedded industrial computer with color LCD touchscreen puts all controls at the operator's fingertips, reducing setup time between jobs and cutting the learning curve for new technicians. 

Parameter	Specification	Practical Benefit for the Shop
Rail Pressure Range	0 – 2800 bar (via Bosch DRV valve)	Covers everything from early CP1 systems to latest piezoelectric injectors running at 2500 bar+
Pressure Accuracy	±0.5 bar	Eliminates false rejects caused by sensor drift-fewer injectors scrapped unnecessarily
Flow Sensor Range	0.008 – 4 L/min	Wide enough for pump delivery tests, fine enough for idle backflow detection on six injectors
Flow Accuracy	0.3%	Catches gradual degradation that causes uneven cylinder contribution and DPF clogging
Motor Power Options	7.5 / 11 / 15 / 18.5 / 22 KW	Match investment to workload-no overspending on capacity you won't use
Speed Range	0 – 4000 RPM	Tests both high-speed HPCR pumps and slower mechanical inline pump applications
Oil Temperature Control	40±2°C (air or forced cooling)	Consistent viscosity means repeatable results shift-to-shift, day-to-day
Voltage	3-phase 220V / 380V (optional)	Drops into existing shop power without transformer costs

For shop owners staring at a shelf full of core returns, parts compatibility is where money gets tied up. This bench tests BOSCH, DELPHI, DENSO, SIEMENS (VDO) injectors, all common rail pumps including the DENSO HP0, and with optional modules, tackles CAT C7/C9/3408/3412 HEUI, FORD 6.0 HEUI, BOSCH VP44, DENSOV3/V4, and EDC-ZEXEL RED4 pumps. Instead of owning three dedicated machines-one for HEUI, one for common rail, one for mechanical-you keep one calibrated platform and free up both capital and floor space. Optional add-ons cover CAT actuation pumps, dual solenoid injectors, and electronic VE systems, letting you expand coverage without swapping hardware or retraining staff. The system also generates QR codes for BOSCH and DENSO injectors, DELPHI C21/C31 codes, and SIEMENS (VDO) IIC codes online-no separate programming tool, no mismatched codes that send a reman injector back as a warranty claim. 

Getting a new test bench online shouldn't mean losing a day of throughput. The CR3000A-708 connects to your existing three-phase supply with minimal electrical work-just match the voltage to 220V or 380V and the power rating to your shop's capacity. The benchtop footprint fits standard workshop layouts, and the cooling system (air or forced, your choice) doesn't require plumbing modifications. Software setup is equally straightforward: remote assistance is available for initial configuration, and online system upgrades keep the database current without waiting for a service call. Data logging exports service records directly, so you can document each repair for fleet customers or warranty claims without manual transcription. 

The repair value goes beyond pass/fail flags. Measuring solenoid inductance tells you if a coil is shorting internally-a failure mode that intermittent resistance checks miss. Armature stroke (AHE) reveals mechanical wear that flow testing alone won't show. BIP response time lets you check timing consistency across six injectors simultaneously, catching drift that causes rough starts and uneven cylinder contributions. These aren't lab curiosities; they're the difference between shipping a pump that runs for a month versus one that stays on the road through a full service interval. Optional modules go even deeper, testing CAT actuation pumps and dual solenoid valve injectors used in heavy-duty off-road equipment. When a $500 injector gets condemned based on a borderline flow reading, these additional diagnostics give you the confidence to either save it or scrap it-and that confidence directly affects your bottom line.

Q1: How do bench test results correlate with on-road injector life under heavy haul?
A: Injectors passing the full-load flow uniformity and backflow tests typically stay within ECU adaptation limits for 100,000–150,000 km under normal service, assuming clean fuel and regular filter changes.

Q2: Can we verify calibration consistency across multiple CR3000A-708 units in different bays?
A: Yes. We supply a master injector set with known values. Running it across machines lets you confirm inter-bench consistency, preventing one unit from passing what another fails.

Q3: How much does the 0.3% flow sensor drift over time, and can we recalibrate in-house?
A: Drift stays under 0.2% over two years with regular zeroing. The bench includes offset correction routines; full traceable calibration is available annually via remote assistance.

Q4: Does the bench detect piezoelectric injector spring wear before installation?
A: Yes. The dynamic test profile measures spring force during de-energization. Weak springs show as delayed closing and excess idle backflow, flagged numerically for rework decisions.

Q5: What throughput can we expect testing reman injectors before shipping?
A: A full six-injector cycle runs under 5 minutes; quick verification takes 1.5 minutes. One bench can process 40–60 injectors in a half-day batch, depending on test depth.
