With a high-performance liquid ring vacuum pump, any suction height is set extremely quickly in a closed loop and kept constant. Physically, this method can be seen as a genuine alternative to systems with suction shafts, as the set suction head and the friction losses on the suction side are taken into consideration and processed separately..

The control valve is used to set the back pressure. The capacity and condition of the water tank is decisive for performing tests that make sense. If the tank capacity too small, this will lead to restrictions, which in each case will result in faulty measurements due to the air delivered to the pumps to be tested.

We therefore recommend containers with a minimum volume of 8,000 l.

The tank will be constructed in the ground in the basement as an underground tank. The pipes and technology will be installed in the hall.
