The special shape and the thickness of the diaphragms has been carefully optimised to reduce mechnical stresses during the working cycle of the pump, also under the most difficult working conditions.
The new patented diaphragm retaining plate, has a shape that minimises the possibility that the diaphragm can get caught or nicked by the diaphragm plate.
We call the combination of the new BlueFlex diaphragms when used with the new patented diaphragm plate, the BlueFlex system. This translates into heavy duty and long diaphragm life.
