Hydraulic advantages: flexibility

Matching the point of optimal performance with the required levels of flow rate and manometric head is now an easy task for the project designer.

For both centrifugal pumps (up to 200 l/s and 350 m in depth) and for axial flow pumps (up to 3,000 l/s and 6 m.c.w.), ADES can provide a list of head, flow rate, torque and absorbed power details for optimal performance points at different revolutions to help project designers to find the most suitable option for each case. For example, slow pumps for cases of sand abrasion or where there is a risk of cavitation (shallow watercourses, reservoirs, etc.) or fast pumps (5,000 r.p.m) for cases requiring high flow rates in wells with small diameter casings.

This flexibility means that our pumps can be adapted to variations in level (on drops, in aquifers or in areas affected by tides) and changing flow rates, whether due to varying pumping requirements or for any other reason.

By simply changing the speed of our equipment, they can easily be adapted to the new conditions without having to close valves which could lead to overloads and cause them to consume higher levels of specific energy.
