Manual Transfer Pump

This hand-operated piston pump fits buckets, drums and pails using the included polypropylene bung adapter. The PVC piston and Viton seals handle detergents, most acids, oils, rinse additives and soda ash. It is self-priming and delivers fluid through the supplied spout without a discharge hose.

Light-Duty Chemical Dispensing

Suits operators who need occasional, portable transfer of compatible liquids from open-top containers. Not suited for metered dosing, high-volume continuous pumping or fluids outside the listed chemical range. Buyers who need a sealed hose connection or automated flow control should look at other equipment.

11/16 Inch Outlet Diameter

The discharge spout has an 11/16 inch outside dimension, which determines fit with receiving vessels or hose attachments. Verify this size matches your container opening before purchase. The pump carries a Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

How deep can the 11/16 in piston reach into a drum before suction breaks?

The self-priming piston draws from the bottom of a standard drum, pail or bucket when the spout is fitted and the bung adapter seals the opening.

Does the PVC piston and Viton seal stay cool during continuous hand operation?

The pump has no motor, so it produces no heat; the lightweight PVC body and Viton seals remain at ambient temperature during extended use.

Which container opening does the included polypropylene bung adapter fit?

The adapter threads into a standard 2 in drum or pail bung hole, letting the pump mount directly on buckets, drums or pails.
