Multiquip Diaphragm Pumps

Affectionately known in the industry as a “MUD or SLUDGE” Pump, they are ideal for the slow seepage applications where a centrifugal pump would ordinarily lose its prime. The positive displacement design and performace is perfect for muddy water, sludge or any water with a high percentage of solids.
