John Blue introduces new DP-282.1

John Blue introduces new update with Duramax Diaphgrams: mechanical elasticity with controlled deformation

New and innovative DuraMax diaphragms are “pre-deformed” and provide longer life and better performance with a wide range of chemicals. The plastic polymer provides great strength and long-lasting reliability.

The diaphragm washer is made of stainless steel to prevent abnormal deformation of the diaphragm and guides it along the piston stroke. The piston crown has a friction-proof form to eliminate wear caused by rubbing.

Here is the features of DP-282:

• The heads are designed with a patented technology that includes an aluminum die-cast core inside a polypropylene structure offering superior strength.
• Washers and diaphragm bolts are 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
