Restore maximum solution flow and prevent dangerous chemical leaks with this premium Replacement Pump Bellows Kit (Part # 21661). Engineered specifically for heavy-duty Tennant sweepers and floor scrubbers utilizing the Gorman-Rupp fluid pump, this complete rebuild kit ensures your machine lays down the exact right amount of detergent for a spotless warehouse floor.
A cracked, dry-rotted, or leaking rubber bellows will cause your Tennant scrubber to lose solution pressure, dumping expensive chemicals inside the chassis and leaving your floors dirty and unsafe. Don't pay outrageous $336+ dealership markups or roll the dice on dried-out "New Old Stock" rubber from eBay liquidators. Our aftermarket Tennant bellows kits are factory-fresh and manufactured to exact OEM tolerances, featuring heavy-duty, chemical-resistant rubber designed to withstand harsh industrial floor detergents. We offer transparent pricing and FAST, FREE SHIPPING across the USA to get your floor cleaning equipment back in action.
