Very simple construction

The ejector works by means of an external pump that sends water, air or another propellant through a nozzle, forming a jet stream. This generates a powerful vacuum which sucks the fluid or gas required from the intake, after which the jet stream transports it through the diffuser and further in the system.

Another ejector run on compressed air can if necessary suck water up to the pump that supplies the water flow to the main ejector.

Many years of experience

The proportions of the ejector's bore and the sizes of the nozzle and intake are determined in each individual case, so that the optimum capacity can be achieved for the pumping height, the capacity of the external pump, and the character of the fluid to be sucked up.

These calculations are very difficult and are based on many years of concrete experience and experiments. It is easy to lose 50% of the capacity if these calculations are not based on reliable data and knowledge. ELLEHAMMER has built up the necessary knowledge over many years and can ensure optimal exploitation of the available pumping power in any imaginable situation.
