The HP-A 55KW Hydraulic Comprehensive Test Bench is an all-in-one diagnostic station engineered for the maintenance and manufacturing of hydraulic components. Unlike standard test benches that only test pumps, the HP-A is designed to rigorously test Hydraulic Pumps, Motors, Valves, and Cylinders on a single platform. It complies with GB3766-88 technical standards, ensuring reliable performance verification.
Powered by a 55KW 4-pole motor and a frequency converter system, this bench provides a controllable speed range of 0-2000 r/min. It features a closed fuel tank structure, making it suitable for operation even in dusty environments while maintaining oil cleanliness (NAS10 standard). The system uses an integrated oil circuit block design to minimize leakage and optimize heat dissipation. With a maximum system pressure of 30MPa and flow rate up to 400L/min, the HP-A is the ideal choice for workshops requiring a versatile, compact, and high-performance hydraulic testing solution. (Optional: Printer available for generating test reports).


Comprehensive Testing: One machine handles four key components: Hydraulic Pumps, Motors, Valves, and Oil Cylinders.
Compact & Integrated: The built-in motor design and integrated oil circuit block save floor space and reduce connection leakage points.
Intelligent Control: Equipped with a PLC touch screen and digital meters for real-time display of pressure, flow, and speed.
Robust Performance: Max pressure of 30MPa and flow of 400L/min allow for testing a wide range of medium-to-heavy duty components.
Dust-Proof Design: The fully enclosed oil tank protects the hydraulic system from contaminants, extending equipment life.
Flexible Loading: Supports manual dual-road loading pressure control for precise simulation of working conditions.
Expandability: Can be upgraded to test Double (Tandem) Pumps with additional flow sensors and accessories.

Q: What is the difference between HP-A and HP-B 90KW Hydraulic Pump Test Bench?
Choose HP-A (55KW) if: You need a comprehensive machine to test Valves and Cylinders in addition to pumps/motors, and you have limited workshop space (Compact internal motor design).
Choose HP-B (90KW) if: You primarily test large-displacement pumps and motors requiring higher power, and you need an external motor setup to accommodate oversized units without space restrictions.
