Saniforce Piston Pumps


Graco’s powerful line of sanitary piston pumps move extremely difficult materials when others cannot. They have pressure ratios up to 12:1 and are ideal for low to medium viscosity materials. The Graco Merkur® air motors improve serviceability, increase efficiency and offer a lower cost of ownership. The quick knockdown lowers are made with 300 series stainless steel for long-lasting durability.

Product Features:

  • Three models with flow rates ranging from 4-14 gpm @ 60 cpm
  • Perfect for fluid transfer and supply of low to high viscosity fluids
  • Available in double-ball and priming piston designs
  • New Graco Merkur air motor technology (4.75 stroke), the most advanced air motor on the market
  • Graco quick knockdown lowers made with 300 series stainless steel
