The Hydraulic Ram Pump, when working at its optimum will pump about 20% of the water that is available to it, to a maximum height of approximately 150 meters. No Running Costs, No Fuel or Electricity, No Pollution, Operates 24 hours a day all year.
The use of heavy wall steel tube for the drive pipe is highly recommended. Upon completion of installation the operator must ensure the pump is is firmly bolted to its concrete base and the drive pipes have been laid out evenly.
A Hydram base, at a minimum a simple concrete slab <150 mm thick, provides a surface on which the hydram may be bolted and which absorbs the pulsations during operation. An enclosure for the Hydram is also ideal as it protects the unit and prevents pollution.
