The Glockemann Pump can be thought of as a major variant of the 200 year old “Hydraulic Ram”.

The “Hydraulic Ram” uses the water hammer principle ─ that bang you sometimes hear when a tap is quickly shut. This ‘bang’ is a high pressure pulse that can be made to pump water.

Think of the Hydraulic Ram as a car stuck in one gear. Due to this limitation it has to have a high ‘drop’ or difference in water level in the river to operate, otherwise it will stall or the ‘clutch’ will wear out.

The Glockemann pump is like a car that finally has a gearbox and therefore can go up a steep hill.

By selecting the right size piston (small diameter for ‘Low’ gear) it can pump to a high ‘head’ with a small ‘Drop’.
