Hand Drum Pump Construction

The Dayton 3BY47 is a self-priming hand drum pump built with a steel body and a chrome-plated housing finish. It uses a polyethylene piston and a packing gland seal for fluid transfer. A polypropylene bung adapter is included for secure container attachment.

Intended Fluids and Limitations

The pump suits degreasers, detergents and waxes in buckets or drums. It is not suited for metered dispensing because it lacks a metering function. Buyers who need an included discharge hose or nozzle should look elsewhere as neither is supplied.

Key Specification for Fit

The pump connects to containers with a 21/32 inch inner diameter and a 3/4 inch outer diameter. This specific sizing determines whether the unit will seal correctly on the intended drum or bucket opening.
