David: There are two "ram type" pumps that might work for the type of application you described. The High-lifter pump which is made in the US and the Glockemann from Australia. HOWEVER, if the pump flow rate of 200 liters per second is from the low area to the river, forget it. With either of these the delivery rate would be several liters per minute. Cost is close to $1000 per pump, depending on the exact size. High-lifters web address is http://www.high-lifter.com/ Glokemann's web address is http://www.gpe-waterpumps.com/ If I were attempting to move that much water, I would investigate building a pitot tube siphon to accomplish the task. It would most probably need to be custom designed and fabricated to meet your requirements. Oso

The main river has plenty of water (over 3000 litres per second) and a head difference at the weir of just over 1m. The area to be pumped lies a further one to two metres below the river, so will need to be raised by 2m to discharge back into the river. Pump flow rate would need to be about 200 litres per second. The pump is required to keep the water level below a fixed level, and will not be required to run continuously - simple automatic starting when required would be ideal. Any ideas on a suitable product to achieve this, where I could obtain one and what it might cost?
