Diaphragm pumps have a number of advantages and potential applications.
They have self-priming properties, can withstand running dry and are suitable for ATEX applications and aggressive media.
However, if the diaphragm breaks, there can be serious consequences.
If the diaphragm breaks, the medium can run out into the air side of the pump. This destroys the pump, which therefore needs to be replaced. This costs money - both in terms of downtime and the cost of a new pump.
Furthermore, the medium could also run out of the pump and into the surrounding environment. This could be a major problem - especially in the event of a hazardous chemical.
But fortunately there is a solution to this.
Our diaphragm pumps from Versamatic's E-series are equipped with a fusion diaphragm that is leak-proof so that no liquid flows into the air side of the pump.
Usually there is a hole in the diaphragm and a nut on the back. There is a risk that the liquid will run backwards or that the diaphragm "cracks" if it is run too hard.
Instead, the fusion diaphragm has thread moulded into the membrane so that it is screwed on. There is thus no leakage path in the diaphragm.
