Robin Gasoline Water Pump – 3 Inch, 5HP Engine - PTG310

Robin 3" Gasoline Centrifugal Water Pump

The Robin PTG310 is a heavy-duty gasoline centrifugal pump specifically engineered for high-volume water transfer in the most demanding environments. Delivering uncompromising commercial-grade reliability, it combines a robust 5HP engine with an advanced self-priming system. This makes it an indispensable tool for construction sites requiring rapid dewatering, large-scale agricultural irrigation, and critical emergency flood drainage. Capable of an astonishing maximum flow rate of 60m³ per hour (1000 L/Min) through its large 3-inch (80mm) connection, it handles massive bodies of water with unparalleled speed and efficiency.

Beyond raw volume, this pump is designed for dynamic operational versatility. It effortlessly pulls water from deep sources with a 7-meter suction head and pushes it uphill to an impressive 30-meter total head. The integrated self-priming mechanism automatically removes air from the suction line, completely eliminating the tedious need to manually fill the entire hose before every single use. This immediate deployment capability is perfectly complemented by a high-quality manual recoil starter, built to guarantee a quick, reliable "first-pull" ignition under tough field conditions.

To ensure long-term durability against abrasive materials and harsh outdoor elements, the pump relies on a high-strength aluminum alloy pump casing and a heavy-duty cast-iron impeller. Despite its rugged industrial construction, the entire unit maintains a highly manageable 28kg dry weight. It is securely housed within a protective tubular steel roll frame that acts as a convenient carrying handle while actively shielding the engine from physical impact on active job sites. With a substantial 3.8L fuel capacity, it provides the sustained power necessary for continuous, uninterrupted heavy-duty operation.

Key Features & Benefits:

• Commercial-Grade Power: Driven by a highly reliable 5HP engine reaching 4000rpm, providing consistent torque and robust power for continuous heavy-duty operation.
