Chop-Check pumps are designed to move medium-to-high viscosity fluids in difficult applications.
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 (46.3 l/min), ensuring efficient transfer of heavy greases, inks, and other viscous materials.
Materials advantages of Chop-Check:
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.
