CRP-HD High Flow Common Rail Pump Test Bench with 18.5Kw Gear Drive 2500 Bar Pressure and 60L/H Fuel Feed Rate

The CRP-HD High Flow Common Rail Pump Test Bench addresses a critical gap in the diesel testing equipment market: the ability to properly test and calibrate the large-displacement common rail pumps used in heavy commercial vehicles, construction machinery, marine engines, and locomotive applications. Standard test benches struggle with the high fuel flow demands of pumps used in 10-liter and larger displacement diesel engines, often resulting in inaccurate flow measurements and premature pump wear during testing. The CRP-HD solves this with an 18.5Kw motor delivering high-torque drive up to 2500 Bar, paired with a proprietary high-flow fuel delivery system capable of sustaining 60 liters per hour feed rate "a 50% increase over standard 40-liter bench systems". The oversized 30-liter oil tank with active circulation pump ensures consistent fuel temperature and cleanliness throughout extended testing sessions, making this bench the definitive choice for workshops servicing mining trucks, port equipment, agricultural combines, and long-haul tractor units.

• 18.5Kw High-Torque Drive Motor: The heavy-duty induction motor provides 120 Nm of continuous torque at low RPM, essential for driving the large displacement pumping elements found in CP3.4, CP4.2, and HP5 series pumps without speed droop under load. Gear-driven transmission eliminates belt slippage entirely.
• 60 L/H High-Flow Fuel Delivery System: A dedicated high-capacity gear pump supplies filtered test oil at up to 60 liters per hour through 12mm internal fuel lines, ensuring the pump under test never starves for inlet fuel even at maximum delivery rates. Flow meter accuracy is ±0.5% of reading across the full measuring range.
• 30-Liter Extended Oil Tank with Active Circulation: The oversized tank features a built-in circulation pump that continuously moves oil through the filtration and cooling circuit, preventing thermal stratification and ensuring uniform oil temperature of 40 ± 2°C at all test cylinder inlets. Dual 5-micron filters protect both the supply and return lines.
• 2500 Bar with Heavy-Duty Rail Assembly: The reinforced common rail assembly is rated for continuous operation at 2500 Bar with a safety factor of 2.5x, featuring a burst disc overpressure protection set at 2800 Bar. The rail incorporates four independent pressure sensor ports for redundant monitoring.
• Gear-Driven Transmission System: Unlike belt-driven competitors, the CRP-HD employs a hardened steel helical gear train with oil bath lubrication, delivering zero-slip power transfer and a designed service life exceeding 30,000 operating hours between major overhauls.
• Industrial PLC Control with Touch Screen: A 10-inch color touch screen running on a dedicated PLC controller provides real-time graphical display of pressure, flow rate, torque, RPM, and temperature curves. Test programs can be configured with multi-stage ramp-and-hold sequences for comprehensive pump characterization.
• Integrated Cooling Tower with Temperature Control: A closed-circuit cooling tower with electronic thermostat maintains test oil temperature within ±1°C of setpoint, critical for accurate flow measurements that vary with oil viscosity. The system is rated for continuous 24-hour operation in ambient temperatures up to 45°C.

The CRP-HD is purpose-engineered for heavy equipment dealerships, mining fleet maintenance centers, port authority workshops, and large independent diesel injection facilities that service the commercial vehicle and industrial engine sector. Its high-flow capability is essential for accurate calibration of large-displacement common rail pumps where standard 40 L/H benches produce erroneous flow measurements due to inlet starvation. The bench is equally valuable for marine diesel service centers servicing workboat and coastal vessel engines, railway maintenance depots testing locomotive common rail systems, and agricultural equipment dealers supporting the increasingly common rail-equipped tractor and combine harvester fleets. Research and development laboratories evaluating next-generation high-flow common rail pump designs rely on the CRP-HD for its measurement precision and robust continuous-operation capability.

Each CRP-HD ships in a reinforced ISPM 15 compliant fumigated plywood crate with integrated shock and tilt indicators for logistics monitoring. The cooling tower is transported in a separate padded compartment within the main crate. The package includes a standard set of BOSCH, DENSO, DELPHI, and SIEMENS pump mounting adapters, a comprehensive high-pressure hose and stainless steel fitting kit, two spare 5-micron filter elements, printed English operation and maintenance manual with exploded parts diagrams, and a two-year standard warranty with optional extension to three or five years. Standard delivery time is 20 to 30 working days. On-site commissioning and operator training are available as premium services with factory engineer deployment worldwide.
