Diaphragm Pumps
Features:
• The heads are designed with a patented technology that includes an aluminum die-cast core
inside w/a polypropylene structure offering superior strength.
• Washers and diaphragm bolts in 316 stainless steel, an exclusive feature.
• Die cast crankcase incorporating a new cooling system.
• New chemically resistant diaphragm material pre-deformed to reduce the amount of deflection,
increasing diaphragm life. The diaphragm material is compatible with most of the corrosive
chemicals on the market today.
• A short crankshaft stroke means the longest life possible.
• New connecting rods in special bronze alloy offer economical and trouble free service.
• 316 stainless steel inlet and outlet check valves.
