SP-3220 centrifugal pump

Centrifugal Pumps Coupled to Hydraulic Motor

(Includes Hydraulic Motor)

  • Patented Vac-U-Seal impeller design creates a vacuum between the impeller and mechanical seal. Lack of pressure on the seal face minimizes seal wear and results in a longer seal life.
  • Double wet seal design provides for continuous lubrication of the seal faces. This wet seal design allows the pump to be run dry for extended periods with no damage to the mechanical seal faces.
  • Closed impeller design minimizes thrust loading on the drive motor extending the life of the drive motor. Impeller wear actually increases performance.
  • Extra thick cast walls provide extra strength and extend the life of the unit due to abrasion and corrosion.

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.
