HM 365.14 Centrifugal pumps, series and parallel connected
In complex systems, pumps can be connected in series or in parallel. In series operation, the heads are added, and in parallel operation the flow rates of the pumps are added. The series and parallel configuration of pumps is very well suited to understand the similarities with an electric circuit.
HM 365.14 is equipped with two standard centrifugal pumps that are delivered ready for installation, mounted on a plate. The centrifugal pumps are installed in the supply unit HM 365.10 with just a few simple steps, connected via hoses with quick-release couplings, and attached with clamping levers. To power the pumps, they are connected to the drive unit HM 365 with a V-belt.
The pressures at the inlet and outlet of the centrifugal pumps are recorded with sensors. The measured values are read from digital displays on the supply unit and can be transmitted simultaneously via USB directly to a PC, where they can be analysed using the included software.
