Piston Pump Packages, Fully Configured for You
ARO's advanced sealant dispensing systems go beyond the pump itself. We deliver complete sealant application systems that combine pumps, accessories, and controls for reliable material handling. Every component is matched to your fluid and process requirements.
Our portfolio handles a wide range of sealant chemistries, including:
- Silicone and RTV sealants
- Polyurethane sealants
- Acrylic and butyl sealants
- Epoxy and structural sealants
Piston pumps serve several roles in a high-viscosity sealant dispensing system. They extrude thick sealants and caulking through applicator guns or valves. They transfer material from drums or totes to the point of use. They also circulate fluid back to the container in continuous-loop systems. The right pump depends on your sealant's viscosity and your process demands.
Two proven pump technologies anchor the lineup:
- Chop-Check piston pumps handle materials from 15,000 to over 1,000,000 cPs, with flow rates up to 46 L/min (12.2 gpm). Primer design prevents cavitation with non-leveling sealants, and flat mechanical valves eliminate stringing.
- 2-Ball piston pumps manage low- to medium-viscosity sealants up to 100,000 cPs, delivering up to 68.6 L/min (18.1 gpm). A dual-ball valve system ensures smooth, consistent delivery.
