Dayton 41TK11 rotary gear pump overview

The Dayton 41TK11 is a bronze rotary gear pump rated for up to 125 psi and a maximum flow of 10.8 gpm. It handles fluids up to 500 SUS viscosity and operates from -20 °F to 210 °F. A 1/2 hp single-phase motor with a totally enclosed fan-cooled enclosure runs on 115/230 V AC. The 1/2 in inlet suits compact plumbing layouts.

Upgrade path from lower-capacity pumps

This unit replaces smaller gear pumps that cannot reach 10.8 gpm or 125 psi. The jump is worth it when the application demands higher flow or pressure than a 1/2 hp motor can deliver. Polyphenylene sulfide gears and a Buna-N mechanical seal extend service life in continuous duty. Suction lift reaches 12.3 ft for flexible mounting.

Ideal for industrial fluid transfer

Builders needing a self-priming bronze pump for oils, coolants or similar media will find the specifications match. Operations requiring flows above 10.8 gpm, pressures beyond 125 psi, or viscosities exceeding 500 SUS should look at larger-frame units. Single-phase sites without 115/230 V supply cannot use this motor.

Questions about this item

What size inlet fitting does the 41TK11 pump require?

The pump has a 1/2 in media intake connection, so a 1/2 in fitting is needed for the inlet.

How do I wire the single-phase motor on this pump?

Connect the motor to a 115/230V AC single-phase supply matching the nameplate voltage; ensure the totally enclosed fan-cooled enclosure is grounded.

When should I replace the mechanical seal on this pump?

Replace the Buna-N mechanical seal if leakage appears at the shaft or after prolonged exposure to temperatures near the 210 Degrees F maximum.
