Tapflo is increasing the T series metal pump capacity with the launching of the new T820 S, a compressed air powered diaphragm pump made from stainless steel AISI 316L. The pump has 820 litre per minute capacity. T820 S can transport corrosive liquids, such as chemicals, volatile alcohols to oils and viscous liquids such as paint and glue. Health-impairing liquids too, can be handled safely because the pump is hermetically sealed.
