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. The Hydraulic Ram Pump will do this 24 hours a day, 7 days a week for many years with no external power required and little or no maintenance.
In order for a hydram to work you require two things, a steady source of running water (drive water) and a working fall. The minimum drive water required is 7 litres a minute, the minimum working fall is 1 meter. If you have both of these, or greater then you have the potential of installing a Blake Hydram.
Each Hydram is made to order and available in a range of sizes from No.1 to No.8.
