Poly Diaphragm Pump DP-282.1-P

3 diaphragms. Through input shaft: 1″ diameter one end, 1-3/8″ 6-spline opposite end. Negative pressure – max: 4.9 ft; intermittent: 9.8 ft.

The DP-282.1-P features new and innovative DuraMax diaphragms. These 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.
