Dual-Fuel GDI Common Rail Pump Test Bench 350 Bar Gasoline 2500 Bar Diesel CRP-DF2

The CRP-DF2 is a dual circuit test bench for workshops that service both gasoline direct injection and common rail diesel hardware. It carries two independent hydraulic systems: a 350 bar low volume circuit with gasoline compatible seals for GDI high pressure pumps, and a 2500 bar diesel circuit for common rail pumps. Switching between them takes one valve selection and a fluid change, not a second machine on the floor.

Both circuits share the drive, the control system and the safety enclosure, which halves the floor space and the capital cost of equipping a workshop for both fuel types. Each circuit keeps its own tank, filter set and flow meter, and the control software refuses to run a diesel recipe while the gasoline circuit is selected, so cross contamination is prevented by design rather than by procedure and memory.

For a workshop moving into GDI work, the practical advantage is simple: the same technician, the same fixture table and the same reporting format apply to both fuel systems. That shortens training and makes it realistic for a small team to quote on both diesel and gasoline pump repairs.

• Two Independent Hydraulic Circuits: a 350 bar gasoline circuit and a 2500 bar diesel circuit share one frame but keep separate tanks, filters and meters, so no cross contamination is possible.
• GDI Compatible Sealing Package: fluoroelastomer and PTFE seals throughout the gasoline circuit resist ethanol blended fuels up to E85 without swelling or hardening.
• Recipe Interlock Protection: the controller blocks a diesel recipe while the gasoline circuit is selected and logs every fluid change with a timestamp for audit.
• Shared Servo Drive And Fixture Table: one 11 kW servo drive and one quick change fixture table serve both circuits, cutting floor space and fixture cost against two separate benches.
• Automatic Purge Cycle: a guided purge routine flushes and dries the selected circuit in fifteen minutes, with a residue check before the next fuel type is admitted.
• Unified Test Reporting: GDI and diesel results are stored in one archive with identical fields, so a workshop can hand over a single report for a vehicle platform that uses both systems.

The bench suits independent workshops and multi brand service centres that already repair common rail diesels and are taking on GDI pump work as the gasoline fleet ages. Component remanufacturers rebuilding both pump types also use it as a single acceptance station for two product lines.

Typical routines include GDI pump delivery and pressure holding tests, diesel pump delivery mapping, return flow comparison across injector circuits on the diesel side, and post repair verification of both systems on vehicle platforms that offer a turbocharged gasoline engine and a diesel variant.

The bench ships in a single fumigated crate with both fuel circuits drained, purged and sealed, and the tanks labelled for transport. An isolation kit with blanking caps and warning tags is included, so the receiving workshop can confirm circuit identity before the first fill.

Factory testing runs both circuits against reference pumps, with a documented purge and cross contamination check between them. The report lists GDI pressure stability, diesel delivery repeatability and the residue test result. Warranty is twelve months on the drive and control system and twenty four months on the frame and tanks.
