Hydraulic Power Pack for Drainage Pumps
Hydraulic power unit configured to supply one or more hydraulically driven drainage pump heads, with matched flow, pressure, and coupler arrangements for dewatering and flood control duties
Distribution arrangement depends on the flow demand of each pump head. Where multiple heads operate simultaneously, a flow divider may be required to maintain stable operation. Configuration to be confirmed against the specific pump head set at order stage.
The Hydraulic Power Pack for Drainage Pumps is an engine-driven hydraulic power unit configured to supply hydraulically driven drainage pump heads used in dewatering, sump clearance, and flood control duties. The unit integrates a 9.0 kW air-cooled gasoline engine with a variable-displacement hydraulic pump rated at 35 L/min and 210 bar, an 18-litre reservoir with 10-micron filtration, and two sets of flat-face quick couplers. Because the pump heads contain no electrical motor or cable, the power pack can supply pumping at locations where electrical equipment in wet conditions is restricted. The pressure-compensated pump adjusts displacement as pump head demand changes, supporting stable pumping as water levels and discharge conditions vary. A single power pack can drive multiple pump heads of matched hydraulic specification, subject to the combined flow demand. The unit is suited to procurement by contractors, municipal drainage departments, and rental operators maintaining a fleet of hydraulic drainage pumps.
Matching requires the hydraulic motor displacement of the pump head, together with the required flow and head at the duty point. The power pack flow and pressure are then selected so the available supply produces the required impeller speed. Buyers should provide the pump head model, motor displacement, and duty point at inquiry stage. If the pump head specification is known but the hydraulic data is not, the supplier can typically match from the pump head model number.
Yes, provided the combined flow demand of the connected pump heads does not exceed the power pack's rated 35 L/min. Where several heads operate simultaneously, a flow divider may be required to maintain stable operation of each head. Buyers planning multi-point dewatering should specify the number of heads and their individual duty points so the distribution arrangement can be confirmed.
Hose length is limited by pressure loss and by the practical handling of the hose at the site. Longer hoses increase pressure loss in the circuit, which reduces the pressure available at the pump head motor. Buyers should provide the distance from the power pack position to each sump, and the supplier can confirm the appropriate hose length and any pressure compensation required. Hoses are supplied to the specified length at order stage.
The power pack can drive pump heads from other manufacturers provided the hydraulic motor displacement, pressure rating, and coupler type are compatible with the unit's supply. Buyers should provide the pump head hydraulic motor specification and coupler type for confirmation. Where the coupler type differs, alternative couplers or adapters can be specified at order stage, subject to confirmation of compatibility and pressure rating.
The 6.5-litre fuel tank provides approximately 3.2 hours at rated load, depending on engine load and the number of pump heads being driven. Because the pump is pressure compensated, fuel consumption falls when pump heads operate against lower resistance or when fewer heads are connected, and runtime can extend beyond this figure. Buyers should confirm refuelling arrangements for extended pumping operations.
Check engine oil level before each use, and clean or replace the air filter according to the operating environment. Inspect hydraulic hoses and couplers for abrasion or leakage, and check the reservoir oil level. Hydraulic oil and return filter should be replaced at the interval specified in the maintenance schedule. For units in standby, run the engine briefly at defined intervals to confirm starting and hydraulic output.
A complete inquiry should include: the pump head model and hydraulic motor specification; the required flow and head at each duty point; the number of pump heads to be driven and whether they operate simultaneously; the distance from the power pack to each sump and the required hose length; the coupler type used on the pump heads; and the expected duty cycle and runtime per shift. For fleet or rental procurement, indicate the estimated quantity and whether the specification must remain fixed across repeat orders.
