Features:
Metering with a multi-head diaphragm pump
Stroke individually adjustable for each head
Multi-head diaphragm pumps are used for metering in many process engineering areas. In food technology, for example, multi-head diaphragm pumps enable the precise observation of mixing ratios in order to ensure consistent high quality of the products. In addition, diaphragm pumps are leak-free and thus prevent germs from entering the piping system. This ensures that the high hygiene requirements that apply in food technology are observed.
Tesca Multi-Head Diaphragm Pump Test Apparatus has three pump heads. Each pump head conveys water from the feed tank into a tank with a scale. The common stroke rate of the three pump heads is set at the switch box. The stroke of each pump head is set directly at the pump. Three overflow valves enable the user to set a counter pressure for each pump head. Manometers indicate the pressures on the intake and delivery side of each pump head. This enables students to examine the effect of the counter pressure on the flow rate and the mixing ratio. A stopwatch for the determination of the flow rate using the scaled tanks is included in the scope of delivery.
