Sealless Diaphragm Pumps

	Air Operated Double Diaphragm Pumps from SandPIPER® offer many advantages over other types of pumps. Low internal velocities move abrasives easily, with no damage to the pump. The gentle pumping action does not sheer fragile materials. Even heavy or solids-laden materials can be pumped - they move everything from water to peanut butter. These air-driven pumps, with no motors, seals or packing to leak, are environmentally friendly. Air Operated Double Diaphragm Pumps from SandPIPER® can run dry without damage, unlike other types of pumps and they are able to dry prime under most suction lift and conditions.
