FM51Series And Parallel Pumps Demonstration Didactic Equipment Vocational Training Equipment Fluid Mechanics Lab Equipment
DESCRIPTION Two motor-driven centrifugal pumps mounted on a stainless steel plinth with a water reservoir and pipework for continuous circulation. The pumps can be configured for single pump operation, two pumps in parallel or two pumps in series by using manually operated ball valves. Similarly, manual valves are used to control the flow and facilitate the study of suction effects, including demonstration of air release. In parallel operation the two pumps draw from a shared inlet pipe of a wider diameter than the pump inlet, reflecting a typical industrial configuration of parallel pumping. Each pump has impellers that can be easily accessed and replaced without tools. The FM51 is delivered with three impellers in total, one with forward curved blades and two with backward curved blades, allowing the students to investigate the effects of impeller characteristics. Electronic sensors measure the pump outlet pressure of each pump, the shared pump inlet pressure, the flow rate and the water temperature. The pump speed of the first pump is accurately controlled by an advanced electronic inverter within the IFD7 (an essential accessory) and can be varied over the full range. The inverter also calculates the torque produced at the motor drive shaft, allowing the power used by the pump to be derived. The second pump runs at inherent motor speed. This combination of control facilities allows a wide range of different configurations to be investigated. TECHNICAL SPECIFICATIONS Max flow rate: 2.2 l/s (parallel pumping, both pumps 50Hz) Max head: 6.0m (single pump) – 12.0m (series) Pump speed: 1,800rpm (pump 1) – 1,500rpm (pump 2)
