Diaphragm Pumps Ltd

TapfloM Air Operated Double Diaphragm (AODD) Pumps are becoming the most common pumps for use when Only Air is available or when pumping solid laden liquids or slurries. TapfloM Diaphragm Pumps have no seals as the diaphragm acts as the barrier between the Liquid side and the drive side of the pump. When the liquid pressure reaches the air pressure, the TapfloM pump reaches a point of balance and stalls without the need for bypasses or overload protection.TapfloM Diaphragm Pumps pump can run dry indefinately and have the ability to self prime to 7 metres or more in some cases. They can handle viscosities up to 20000 Centipoise as standard and some TapfloM models can handle cPs into the 100's of 1000's.
