This Graco 273295 Pump Lower Kit provides a carbon-steel lower assembly with ProConnect technology for fast motor-to-lower change-outs — ideal for quick drum swaps and minimal downtime.
The
Graco 273295 Pump Lower Kit is engineered for high-performance transfer of A and B materials in foam and coating applications via the Reactor® spray system. Built with a heavy-duty carbon-steel lower, it supports the proven Merkur® air-motor and delivers a 3:1 ratio
pump configuration with integrated ProConnect™ quick-release technology, allowing the air‐motor to be detached rapidly from the lower. This plug-and-play feature enables operators to swap out lowers between drums easily, reducing residue drips, simplifying setup, and limiting rig ceiling height requirements. It also offers significant downtime reduction by enabling the installation of a ready-spare lower while maintenance is performed. The kit is typically supplied “bare” (lower only, no motor) and is compatible with pneumatic piston
pump applications. Durable construction, ease of maneuvering between drums, and rapid maintenance turnaround make this kit a smart choice for professional spray operations.
