Product Overview

The Interpump E3B2515I-HY26 Hydraulic Motor Pump Unit is a professional hydraulic-powered pressure washer pump designed for mobile, agricultural and industrial cleaning systems. It combines a heavy-duty Interpump high-pressure water pump with a 26 cm³/rev hydraulic motor, providing a compact solution where an electric motor or petrol or diesel engine is unsuitable.

The unit delivers a maximum water pressure of 250 bar, with water flow rates of 15 LPM at 1450 RPM or 20 LPM at 1950 RPM. At 1450 RPM, the hydraulic motor requires approximately 42 LPM of hydraulic oil at 130 bar. At 1950 RPM, the requirement increases to approximately 56.5 LPM at 130 bar.

This hydraulic MPU is suitable for installation on tractors, agricultural machinery, construction equipment, utility vehicles and purpose-built mobile pressure-washing systems.

Please contact us before ordering if you require help confirming the hydraulic oil flow, operating pressure or compatibility with your equipment.

Bulk purchase discounts are available on request.
