Rotary diaphragm pump uses novel composite and reinforced rubber moulding
Using the patented pumping technology of the RD5 rotary diaphragm pumpCharles Austen Pumps is extending the range to include the RD1a new smallerlow-cost version.
Inside the pumpthe active part is a novel composite reinforced rubber moulding. This moulded rotary diaphragm deals with all the sealing and pumping functions in one gomuch as the tube in the peristaltic pump doesbut without the inconvenience of servicing and replacing worn tube.
Through the orbiting action of the diaphragmthe RD1 achieves a remarkable lift of 7mtogether with the ability to pump air and water up 20m. This innovative design means the liquid comes into contact with only two partsnamely the diaphragm and the pump bodywhich are available in food grade material and are capable of pumping hot liquids up to 98¢ªCmaking it suitable for beverage dispense and sterilisation.
Lightweight componentsslimline design and the ability to orientate the pump connectors have been incorporated to minimise weight and save space. Offering over 3000 hours of servicethe RD1 has no sliding partsso wear and maintenance are kept to a minimum. The RD1 is self-priming and is able to tolerate suspended solids and run dry without damage.
Proving excellent as a dosing pumpthe RD1 accurately pumps the same volume of liquid each revolution. A Hall Effect sensor is used to sense the number of revolutions the pump makes when it is running. Using a combined revolution counter and controllerthe pump can be set to run for a predetermined number of revolutions. This allows the operator to accurately dose specific volumes of liquidtime and again. Additionallysimply by switching the polarity of the DC input voltagethe user can reverse the direction of flow.
Potential applications include water samplingvendinghydroponicsindustrial cleaning machinescondensate removal and the dosing of liquids for purification.
