Dayton 32ZN71 piston drum pump

The Dayton 32ZN71 is a hand-operated piston pump built for 5-gallon pails. Its 316 stainless-steel body and PTFE wetted parts handle fluids up to 650 SUS viscosity and 140 degrees F. It delivers 7 ounces per stroke through a 6-inch stainless-steel discharge tube.

Installation and common issues

Thread the 1/2-inch inlet into the pail opening and align the 11/32-inch outlet tube. PTFE seals and gaskets resist chemical attack but can gall if forced; hand-tighten only. The piston’s PTFE rings wear faster with abrasive media, so flush after each use to prevent scoring.

Pre-order checks

Verify the pail neck accepts a 1/2-inch inlet and that your discharge hose fits an 11/32-inch ID tube. Confirm fluid viscosity stays below 650 SUS and temperature below 140 degrees F. Ensure 316 stainless and PTFE are compatible with the chemical being transferred.

Questions about this item

How can I verify the pump is working correctly after setup?

Each full stroke should deliver approximately 7 ounces of fluid. With a 5 gallon pail in place, confirm smooth piston action and check that liquid exits the 11/32 inch outlet without leaks at the PTFE seals.

What comes with the pump and what must I buy separately?

The unit includes the pump body, piston, PTFE seals and a 6 inch stainless steel discharge tube with 11/32 inch ID and 1/2 inch OD. A compatible 5 gallon pail and any additional hose or fittings for your application are not included.

Which pump capacity should I choose for my container?

This model is specified for use on 5 gallon pails. If your container matches that size, the 7 ounce per stroke output and 650 SUS viscosity limit cover typical automotive and RV fluids.
