Graco’s SaniForce High Sanitation Electric Operated Double Diaphragm pumps reduces energy consumption up to 5 times compared to traditional air-operated diaphragm pumps. They provide the same great self-priming, stalling, seal-less design coveted by air operated pumps in an electric package that can solve many of the problems associated with rotary positive displacement pumps. Graco's patented air-charged center all but eliminates pulsation on the fluid outlet of the pump providing a smooth steady flow idea for in process applications, filling systems, and sanitary/hygienic applicator applications.

How it works?

Different than an air-operated diaphragm pump this pump uses an electric drive instead of compressed air to move the diaphragms. The center section is filled with pressurized air and is mechanically moved left/right by the motor, pushing and pulling the diaphragms from left to right. This back-and-forth motion, forces liquid out of one chamber into the outlet manifold, while filling the opposite fluid chamber via the inlet manifold

Advantages of the SaniForce High Sanitation electric pump

  • Energy efficient electric drive
    Electric drive reduces energy consumption up to 5 times and provides additional pump control
  • PTFE/EPDM overmolded Diaphragms (bolt-through options available)
    • Improve wear and diaphragm life with no exposed diaphragm plates on the fluid side
    • No crevices for harboring bacteria
    • Longer diaphragm life in abrasive applications that require PTFE
    • PTFE on fluid side and EPDM on the air side
  • Tri-clamp and DIN connections allow easy cleaning and minimal downtime
  • 32Ra formed/welded stainless steel with sanitary finish
  • Patented air charge reduces pulsation for smooth flow and allows the pump to stall under pressure increasing system safety and removing requirement for circulation loops
