Pneumatic Dual-Component System for 1:1 Bridge Expansion Joint Materials in 5 Gallon Pails
A dispensing system for bridge expansion joint sealing and similar applications, this machine is a pneumatic dual-component piece of equipment engineered for dispensing 1:1 ratio bridge joint sealants directly from paired 5-gallon pails.
Compact, portable, and all-pneumatic, this system delivers precise metering and consistent flow for demanding roadway and infrastructure applications. While largely a bridge expansion joint sealing dispensing system optimized for silicone sealants like Dowsil 902, this machine can also be configured for use with other two-part chemistries, including methacrylates (MMAs), urethanes, and epoxies for applications such as epoxy dowel bar placement.
Performance Highlights
-
Precision Dual-Component Dispensing: Designed for accurate 1:1 metering of high-viscosity bridge joint sealants and other 2-part chemistries
-
All-Pneumatic Operation: Requires no electricity, making it ideal for job sites with limited power access or safety restrictions
-
Portable, Compact Design: Built with a lightweight frame that enables easy transport and setup for field-based infrastructure work
-
5-Gallon Pail Compatibility: Engineered to dispense directly from paired 5-gallon pails, ideal for field applications and standardized supply setups
-
Customizable Applicator Options: Compatible with high-output or precision-volume applicators to suit your production needs
-
Extended Reach Capability: Supports hose lengths up to 50 feet for flexibility in challenging or spaced-out work zones
-
Consistent Flow Rates: Delivers up to 1.00 gallon per minute, depending on material viscosity
-
Made in the USA: Built with high-quality materials and domestic support
