RPD40T Portable Diesel Pump | High-Pressure & Efficient Water Transfer

Introducing the RPD40T, a flagship model from DEHRAY’s RPD series of portable diesel pumps—designed to deliver exceptional water transfer performance for agricultural irrigation, construction dewatering, emergency flood control, and industrial water supply. Adhering to DEHRAY’s “RELIABLE POWER FOR EVERY NEED" philosophy, this pump boasts a maximum flow rate of 40 m³/h and a head of 50 meters, powered by a high-torque diesel engine that ensures stable operation even in harsh working conditions.

The RPD40T stands out with its robust diesel power system, featuring a 4-stroke single-cylinder engine that offers superior fuel efficiency and long service life compared to gasoline counterparts. It holds international certifications including CE, ISO9001, and EPA, guaranteeing compliance with global quality and emission standards. Its portable design (net weight 85kg) is complemented by a durable steel frame with anti-vibration rubber pads, while the oversized fuel tank and efficient cooling system enable extended continuous operation without frequent maintenance.

What truly distinguishes the RPD40T is its high-pressure centrifugal pump core—equipped with a wear-resistant cast iron impeller and mechanical seal that minimizes leakage and ensures consistent performance. With a suction lift of up to 8 meters and a discharge diameter of 4 inches, it can handle water with mild solids (up to 3mm) making it versatile for various scenarios. The easy-start recoil system and intuitive control panel simplify operation, while the low-noise muffler reduces working noise to 78 dB(A) at 7m. Whether you’re irrigating farmland, draining construction sites, or supplying water to remote areas, the RPD40T delivers powerful, reliable, and efficient water transfer solutions.
