Self-priming and dry-run safe
Diaphragm pumps have many advantages. They are self-priming and can run dry without damage to the pump. They have no mechanical seals because the shaft seals are not inside the pump. All pumps have variable capacity through a simple control fitted as standard on the pump. They do not damage the pumped product and have low maintenance costs. They are widely applicable: from thick to thin and abrasive liquids. For example, a free passage of up to 76 mm for liquids with large solids can be realised and piping can be kept under pressure against a tight valve. Thereby, the pump starts and stops automatically when opening and closing the discharge valve.
