Diaphragm Pumps

Single Diaphragm D Series

Diaphragm pumps are ideally suited for all sectors of the construction industry as well as for municipal and industrial applications where dry priming pumps are required. They are particularly useful for pumping muddy water, sludge or any liquid with a high percentage of solids. One of the best features of the diaphragm is that they can run dry indefinitely without damage.
