AF0423 Series Chop Check Piston Pumps

  • 23:1 Ratio
  • Max Flow: 1.8 GPM (6.81 l/min)
  • Max Fluid Pressure: 3,690 psi (25,4 bar)
  • Lower pump material available in carbon steel or stainless steel

Chop-Check piston pumps are designed to move medium-to-high viscosity fluids in difficult applications.

The heavy-hitters of the line, ARO Chop-Check pumps are designed to move medium-to-high viscosity fluids ranging from 15,000 cPs to more than 1,000,000 cPs, and at delivery rates up to 12.2 gpm (46.0 l/min).

Applications advantages of Chop-Check:

Extrusion: Chop-Check pumps are workhorses, able to deliver viscous adhesives, sealants, caulking, and heavy lubricants to the application point at the desired pressure and flow rate.

Transfer & Supply: Depending on the model, some Chop-Check pumps are capable of achieving flow rates up to 12.2 gpm (46.0 l/min), ensuring efficient transfer of heavy greases, inks, and other viscous materials.

Materials advantages of Chop-Checks:

Chop-Check pumps have a primer piston to ‘feed’ material into the pump. They are often used in conjunction with a follower plate to force material down. This prevents loss of prime due to channeling—a condition where the pump inlet becomes surrounded by air due to the cavity formed when a high viscosity material does not level off when removed (slumpability).

  • Stringy materials: Chop-Checks have mechanical, flat checks to overcome materials that resist cut-off and adhere to themselves.
  • Tacky materials: Chop-Check pump options come in high ratios to generate the fluid pressure needed to move materials that will adhere to hoses and equipment while wet.
