Industrial A16622 Bare Pump With Head Unloaders

The DEWALT A16622 bare pump with head unloaders is the pump assembly component designed for use in DEWALT’s A16622 industrial system. It is delivered as a bare unit—no motor, drive hardware, or additional accessories—so you replace only the pump core when servicing your equipment. The assembly includes head unloaders, a feature that manages hydraulic pressure at the pump heads during operation and shutdown, helping to reduce wear and enable smoother restarts. Identified by the A16622 designation and associated EMGLO labeling in its packaging, this part is intended for replacement or repair of the pump body in compatible DEWALT configurations. Use this bare pump with head unloaders to restore high-pressure pumping capability in your existing setup; verify that your drive shaft, mounting, and plumbing match the required fit before installation. The part name communicates its role clearly to technicians maintaining industrial DEWALT equipment, and its standalone pump core supports streamlined servicing without unnecessary components.
