Chop‑check piston pumps are positive‑displacement pumps designed to move medium‑ to extremely high‑viscosity materials in demanding industrial applications. 

Typical Applications 

Chop‑check pumps are commonly used where material consistency and cut‑off control are critical.

  • Adhesives, sealants, caulking, and mastics
  • Heavy lubricants and greases
  • Inks and other stringy materials
  • Bulk material transfer and extrusion processes
