Hand Drum Pump for Fluids

The Action P-490 is a hand-operated drum pump constructed from polypropylene for chemical resistance. It is designed for transferring lubricants, detergents and certain alcohols from buckets, drums or pails. The pump includes a bung adapter with an MNPT connection and a spout for direct dispensing. It suits workshops and facilities needing manual fluid transfer without electrical power.

Adjustable Stroke Volume

Each stroke delivers an adjustable volume of 8, 10 or 12 oz, giving the operator control over flow rate for different container sizes. The pump is self-priming and can run dry without damage, which reduces the risk of failure if the source container empties unexpectedly. Maximum outlet pressure reaches 8 psi, limiting use to low-pressure transfer tasks rather than high-pressure injection or spraying applications.

Polypropylene Construction

All wetted parts, including the piston, seals and adapter, are made from polypropylene for broad compatibility with the listed fluids. The blue body provides visual identification in a busy workspace. No discharge hose or metering nozzle is included, so the pump is best suited for open-container pouring rather than closed-system filling. The 55/64 in spout connection fits the supplied spout directly.

Questions about this item

Will the 55/64 in spout fit the bung hole on my existing 55-gallon drum?

The pump includes a polypropylene bung adapter with MNPT threads designed for standard drum openings; the 55/64 in spout connects to that adapter for a secure fit.

How can I confirm the adjustable stroke is delivering the chosen 8, 10 or 12 oz per stroke?

Prime the pump, set the stroke adjuster to the desired mark, then measure the discharged volume in a graduated container over several strokes to verify output.

Does the box contain a discharge hose and nozzle, or must I buy them separately?

The package includes the pump body, spout and bung adapter only; a discharge hose and nozzle are not supplied and must be purchased separately.
