The WSC55 Chemical Sprayer - Full Set Up is a premier, all-inclusive mobile chemical spraying system designed by Multiquip to deliver unmatched performance, cost savings, and versatility for concrete contractors and finishing professionals. With a rugged cart, powerful Honda engine, onboard compressor, efficient pump, and adaptable hose/nozzle assembly, the WSC55 maximizes productivity and minimizes chemical waste—making it a top choice for serious crews tackling slab curing, sealing, evaporation control, and other high-demand jobsite spraying tasks.
Complete System Overview
The Multiquip WSC55 Chemical Sprayer - Full Set Up is engineered for jobsite efficiency from start to finish. Its robust platform holds either a 55-gallon drum or up to four 5-gallon buckets, letting crews choose the best product source for any task. Clever engineering features, like the sloped chemical platform, channel all liquid toward the suction pickup, virtually eliminating the typical 2–5 gallons lost as residue. This means less chemical waste, lower costs, and easier cleanup after every project.
The full setup comes equipped with:
-
Sturdy mobile cart with non-marring treadless wheels
-
Powerful 5.5 HP Honda GX160 engine
-
Sprayer pump (roller type) capable of delivering up to 18 GPM max
-
Integrated small compressor for line flushing and product recovery
-
Standard 50-ft hose, optional hose reel for up to 150 feet
-
Multiple nozzle choices with onboard storage
-
Quick connect fittings for rapid set up/break down
Key Features and Advantages
-
Onboard Compressor: Unique to the WSC55, the mini-compressor allows operators to clear and recycle leftover product from spray lines, leading to near-zero chemical waste and greatly simplified maintenance at the end of each job.
-
User-Friendly Control Station: Dual levers at the cart handle let users instantly engage either pump or compressor as needed, making operation and changeover fast and intuitive.
-
Flexible Container Handling: Accepts both large drums for commercial-grade jobs as well as multiple small containers for specialty or limited-use chemicals.
-
Non-Marring Wheels: Three smooth, treadless tires protect delicate slab surfaces and prevent concrete marking, outperforming competitive sprayers with utility or hard rubber wheels.
-
Quick Disconnect Hoses: Rapid swaps mean minimal downtime between chemical changes, maintenance, or reconfiguration during high-volume operations.
-
Onboard Tool Tray and Nozzle Storage: Keeps essential spray gear within reach, making multi-nozzle projects more efficient without having to leave the jobsite.
