Pneumatic Double Diaphragm Pumps
Rockingham Systems uses and supplies Larius and SKF Lincoln Industrial Pumps. When using these pumps we will analyse the application, chemical composition of the product to be used and required performance. We will then select the required gasket kit for the application and if necessary we make internal modifications to optimise how the pump works.
Diaphragm pumps work by introducing compressed air through the pneumatic exchange behind one of the two diaphragms, which generates compression and pushes the product into the delivery duct, at the same time the opposing diaphragm creates a vacuum and intakes product.
Once one stroke has been completed the pneumatic exchanger diverts the compressed air to the opposite diaphragm and the cycle is reversed.
Some of our diaphragm pumps carry ATEX certirfication, and they all come in either Aluminum or Stainless Steel, offering maximum flow-rates of 21-900 Litres per minute.
