Hand Drum Pump for Fluids

The Action P-490S is a hand-operated drum pump designed to dispense lubricants, detergents and certain alcohols from buckets, drums or pails. Its polypropylene piston and seals resist chemical attack while the self-priming mechanism starts flow without external assistance. A bung adapter is included for secure container mounting. Adjustable stroke settings deliver 8, 10 or 12 oz per stroke for controlled dispensing.

Suited Applications and Limits

This pump suits workshops and maintenance teams that need portable, power-free transfer of compatible fluids in moderate volumes. It is not suited for high-pressure delivery, metered dosing or fluids outside the listed chemical compatibility range. Buyers who need a discharge hose, a nozzle or electric operation should look at alternative equipment.

Key Specification: Outlet Pressure

Maximum outlet pressure is 8 psi, which determines whether the pump can overcome the back-pressure of your dispensing setup. Verify that 8 psi meets the requirement of your intended application before purchase.

Questions about this item

Should I set the pump to 8, 10 or 12 oz per stroke for my application?

Choose 8 oz for thinner fluids like detergents, 10 oz for medium viscosity lubricants, and 12 oz for thicker compatible fluids; all three settings are adjusted on the same pump.

What does the 8 psi maximum outlet pressure mean when I am actually pumping?

It is the peak pressure the pump can develop at the spout; in practice it limits the height you can lift fluid and the resistance of any attached hose or nozzle.

Will the 55/64 in spout connection fit my existing hose or pipe?

The spout accepts a 55/64 inch connection; match it to a hose barb or fitting of the same size for a secure, leak-free joint.
