Transportable, Modular Lift Pump

Research and Development

The design and engineering departments of RWE undertook the development of a transportable, modular lift pump unit capable of transferring up to 40 Mega Litres of water per day at a total dynamic head of 9m. When creating the development brief for this project various considerations were made to optimise the use and productivity of the lift pump these include:
• Self-priming pumps/systems
• 9m suction head, 3m delivery head
• Diesel motor-driven units
• Remote monitoring and control capability
• Sound attenuation, these units could be used near residential housing where 24hr noise would be a problem.
• Skid-mounted but need to consider trailer mounted as well.
• Variable pumping capacity, range dependent upon driver RPM.
• Upstream level sensor – engine cut off safety switch.
• Mobility – easy to shut down, relocate and set up in a reasonably short timeframe.
• Security covers for the pump and diesel tank, and antitheft trailer locks.
• Water flow measurement.

Build Specification

To meet the development brief we opted for a John Deere 6068T1 Diesel engine coupled with a custom made 16-inch KY pump with a 20-inch suction neck via an SEW Gearbox. The engine, gearbox and Diesel Dog engine controller are housed inside a CJ Perry sound attenuation canopy to keep noise levels to a minimum. Underneath the canopy, a 550-litre bunded fuel tank was used to keep the pump running for a minimum of 24 hours.

To allow the pump-set to be used in many configurations, 630mm PN6.3 pipe spools were fabricated in 3 and 6-metre lengths. Each of these lengths has stub flanges and backing rings at both ends to create truly modular delivery options. 600mm Krohne 0 upstream/0 downstream water meters were mounted on skids with short pipe spools at each end to allow the meters to be placed anywhere in the system, this allows accurate flow measurement to be obtained.
