The diesel engine double-suction pump is a complete, independent and mobile large-flow water delivery unit that combines the classic horizontal mid-closed double-suction centrifugal pump with a high-performance diesel engine through a highly elastic coupling, forming a direct connection. It has overcome the absolute dependence on a fixed power grid, integrating the powerful diesel engine, long-lasting endurance, smooth operation of the double-suction pump, and high-efficiency large-flow characteristics. This unit is the ultimate water delivery solution for rapid deployment and reliable operation in scenarios such as emergency rescue, field construction, agricultural irrigation, water supply and drainage in areas without grid power, and military support.

Products features

Self-powered, deployment without boundaries: Powered by a diesel engine, it does not require an external power source. It can be put into operation immediately in remote areas without power grid coverage, on construction sites in the wild, or at disaster-stricken sites with power outages, achieving truly "anytime, anywhere, ready to use" operation.
Flexible mobility, rapid response: Usually installed on heavy steel mobile trailers or skid bases, it is equipped with off-road tires, brakes, indicator lights, and traction devices. It can be quickly towed by vehicles to any location where operation is needed, enabling rapid response to sudden water delivery demands.
Strong power, high reliability: Matched with industrial-grade diesel engines with high torque and low fuel consumption, it has good starting performance, strong overload capacity, and can adapt to harsh environments with large voltage fluctuations or complete power outages. The power system is optimized to match the pump unit, ensuring continuous and stable output under high head and large flow conditions.
Double suction pump core, excellent operation: The pump body adopts a horizontal split double suction structure, running smoothly, with low vibration, and convenient maintenance. It inherits all the advantages of double suction pumps, such as large flow, high efficiency, and good anti-suction performance, making it an ideal core for efficient water delivery.

Work mode

Preparation for startup and positioning: The unit is transported to the operation site by the towing vehicle, and the outriggers are firmly fixed. Check the diesel, engine oil, and coolant, and connect the inlet filter and the outlet pipeline.
Power startup and pumping: The operator manually or electrically starts the diesel engine. After the diesel engine is preheated at idle speed, gradually increase to the rated speed. The power is directly driven by the coupling to drive the pump shaft and the impeller to rotate at high speed. A vacuum is formed in the pump, and the liquid is sucked in from the double suction inlet, pressurized by the impeller, and then discharged from the volute outlet, starting the large flow water transportation.
Operation monitoring and adjustment: During operation, the operator monitors the diesel engine instruments (speed, water temperature, oil pressure) and the operation status of the pump (pressure, vibration). The diesel engine throttle can be adjusted to adjust the pump speed within a certain range continuously, thereby linearly controlling the flow rate and head to adapt to changes in the working conditions.
Shutdown and movement: After the operation is completed, gradually reduce the diesel engine speed, idle for a moment before shutting down. Close the inlet and outlet valves, dismantle the pipeline, retract the outriggers, and then be towed by the vehicle to the next location or returned to the warehouse.

Application fields

Emergency flood control and disaster relief: emergency drainage for urban flooding, emergency water supply for river embankment breaches, remote water supply for fire prevention.
Temporary water supply for municipal and construction purposes: temporary water supply during pipeline maintenance, drainage of foundation pits at construction sites, municipal cleaning.
Agricultural irrigation and drought resistance: irrigation of farmland in areas without electricity, water diversion and transmission from reservoirs and ponds.
Industrial and mining drainage: emergency drainage in mines, temporary precipitation reduction during construction, backup for industrial circulating water systems.
Field operations and military support: water supply for military field camps, water supply for oil exploration camps, water transportation for forest fire prevention.
