  • Delivers up to 4.8 gpm flow rate for efficient fluid transfer
  • Handles viscosity up to 500 SUS for thicker media pumping
  • Operates at maximum 125 psi pressure for demanding applications
  • Runs between 32 and 280 °F for wide temperature range use
  • Three-phase 230/460 V motor with TEFC enclosure for reliable operation

Dayton 41TK13 Rotary Gear Pump

The Dayton 41TK13 is a rotary gear pump rated for 1 hp and a maximum flow of 4.8 gpm at 125 psi. It suits industrial fluid-transfer tasks where a cast-iron body and steel spur gears handle lubricating oils or similar media up to 500 SUS viscosity. Three-phase 230/460 V AC power and a totally enclosed fan-cooled motor support continuous duty in fixed installations.

Cast iron body, Viton mechanical seal, 1/4 in inlet

The cast-iron housing and steel spur gears resist wear from abrasive or viscous fluids, while the Viton mechanical seal maintains integrity across a 32 °F to 280 °F operating range. A 1/4 in intake connection and 3.5 ft maximum suction lift determine plumbing layout and net-positive-suction-head requirements for reliable priming.

Fixed-plant lubrication circuits.

This pump fits stationary hydraulic or lubrication systems that can provide three-phase power and accommodate the 125 psi pressure ceiling. It is not suited for mobile equipment, portable skids, or applications needing higher flow, lower viscosity handling, or single-phase supply.

Questions about this item

How often should the mechanical Viton seal be inspected or replaced on this rotary gear pump?

The pump uses a mechanical seal made of Viton; inspect it during routine maintenance and replace it if leakage appears around the shaft, as seal life varies with the 32 to 280 °F operating range and the 500 SUS maximum viscosity fluid being handled.

What limits continuous duty before the motor overheats?

The 1 hp three-phase motor in a totally enclosed fan-cooled enclosure is rated for continuous operation at up to 125 psi discharge pressure and 280 °F fluid temperature; exceeding either limit will cause thermal overload first.

How loud and hot does the pump get when running all day at 4.8 gpm?

The totally enclosed fan-cooled motor dissipates heat through its external fins, keeping surface temperatures within the 280 °F maximum fluid rating, while the spur gear design and cast-iron body produce typical industrial gear-pump noise levels during sustained 4.8 gpm flow.
