The ID PW38 Gasoline Water Pump is a heavy-duty, portable 4.8 kW (6.4 HP) petrol-powered water pump machine engineered for high-volume irrigation, drainage, flood relief, and construction dewatering applications across agriculture, civil engineering, and emergency services. Driven by a reliable 168FE 4-stroke gasoline engine at 3,600 RPM, the PW38 delivers a maximum flow rate of 600 litres per minute (36 m³/h) through a 38mm outlet pipe, with a maximum suction lift of 26 metres and a suction distance of 8 metres — making it effective for deep well pumping, multi-storey water transfer, and large-scale field drainage. Featuring a self-priming centrifugal pump, a recoil start system, and a 600ml oil tank supporting up to 2.5 hours of continuous operation, the PW38 is built for sustained, high-output performance in the most demanding field environments.

The ID PW38 runs on pure unleaded gasoline (petrol) — no oil-fuel pre-mixing is required. The 168FE 4-stroke engine uses a separate engine oil system, meaning you fill the fuel tank with straight unleaded petrol and maintain the engine oil level independently via the oil tank. This is a significant operational advantage over 2-stroke water pumps, which require a precisely mixed petrol-oil fuel blend. Always use fresh unleaded petrol (minimum 90 RON) and check the engine oil level before each use session. Refer to the included guide book for the correct engine oil specification and capacity.
Yes — the PW38 is well-suited for construction site dewatering and flooded space drainage. Its 8-metre suction distance allows the pump to be positioned at ground level while the suction hose reaches into a flooded basement, trench, or excavation. The 26-metre maximum suction lift provides sufficient head to discharge water to a drain or collection point at a significant elevation above the pump. The 600 L/min flow rate ensures rapid water removal even from heavily flooded areas. Note that the PW38 is designed for clean or lightly contaminated water — heavily silted or debris-laden water may require a trash pump with a larger impeller clearance.
The PW38 features an 8mm inlet pipe connection for the suction hose and a 38mm outlet pipe connection for the discharge hose. When selecting hoses, ensure they are rated for the pump's maximum suction lift of 26 metres and are constructed from reinforced material capable of withstanding the negative pressure on the suction side without collapsing. Discharge hoses should be rated for the pump's flow pressure. Use hoses with the correct internal diameter and compatible fittings to match the pump's inlet and outlet ports — refer to the included guide book for recommended hose specifications and connection torque requirements.
Initial priming of the PW38 is required before the self-priming centrifugal pump can begin drawing water automatically. To prime, first ensure all hose connections are secure and airtight. Locate the priming port on the pump housing — typically a cap or plug on the top of the pump casing — and fill the pump chamber with clean water until it reaches the port opening, then replace the cap securely. Connect the suction hose to the water source, ensuring the inlet is fully submerged and the included inlet filter is attached. Start the engine using the recoil start and allow the pump to run — it will automatically evacuate remaining air from the suction line and establish continuous water flow within seconds to minutes depending on suction line length.
The PW38 supports up to 2.5 hours of continuous operation on a full tank of fuel. After each use session, allow the engine to cool before performing maintenance. Check and top up the engine oil to the correct level using the dipstick — the 4-stroke engine requires clean engine oil separate from the fuel. Clean the inlet filter to remove any debris or sediment that may have accumulated during pumping. If the pump will not be used for an extended period, drain the fuel tank and run the engine until it stops to prevent stale fuel from gumming the carburettor. Store the pump in a dry, sheltered location and check all hose connections and fittings for wear before the next deployment.
If the engine is running but no water is being discharged, the most common cause is a loss of prime — air has entered the suction line and the pump can no longer draw water. Stop the engine, re-prime the pump chamber with clean water, check all suction hose connections for air leaks, and ensure the inlet is fully submerged in the water source with the inlet filter attached and unobstructed. Also verify the suction hose has not collapsed under negative pressure — use a reinforced suction hose rated for the pump's lift capacity. If the pump primes but flow is weak, check that the suction lift does not exceed 8 metres horizontally and that the total vertical lift is within the 26-metre maximum.
Power loss during operation on the PW38 is most commonly caused by low engine oil level, a partially blocked inlet filter, stale or incorrect fuel, or a clogged air filter. First, stop the engine immediately and check the engine oil level — the 4-stroke engine has a low-oil protection system that may reduce power or shut down the engine to prevent damage if oil is insufficient. Clean or replace the inlet filter if it is blocked with debris, as restricted water flow increases pump load and reduces engine efficiency. Check that the fuel is fresh unleaded petrol and the air filter is clean and unobstructed. If the issue persists after addressing these points, the carburettor may require cleaning or adjustment — consult the guide book or contact your point of purchase.
