The unit consists of four different types of pumps namely- centrifugal, turbine, reciprocating and axial flow pump, a common storage tank, and measuring instruments. Each pump is driven by a motor dynamometer for measuring TRUE pump input power. Speed control is by an inverter. By manipulating flow control valves and a selector switch, each pump can be operated individually. The unit is floor standing with removable supports.
