Dayton

Dayton 41TK18 Rotary Gear Pump 1/2 hp 125 psi

SKU CH-B2S0-3FN48

Delivers up to 10.8 gpm at 125 psi with a 1/2 hp motor, handling fluids to 500 SUS viscosity and 280 °F

  • Delivers up to 10.8 gpm flow rate for efficient fluid transfer
  • Handles viscous media up to 500 SUS for versatile pumping applications
  • Operates at maximum 125 psi pressure for demanding system requirements
  • Mechanical seal with Viton material ensures reliable leak prevention
  • Three-phase 230/460 V AC motor with TEFC enclosure for durable performance

Industrial rotary gear pump

The Dayton 41TK18 is a three-phase rotary gear pump built for continuous industrial fluid transfer. It suits maintenance teams and process engineers who need reliable positive-displacement flow in fixed installations.

Thermal and power profile

The totally enclosed fan-cooled motor runs on 230/460 V AC and delivers up to 1-1/2 hp while handling media temperatures from 32 to 280 degrees F. Enclosed cooling keeps surface temperatures controlled and noise predictable during extended duty cycles.

Pressure and flow limit

Maximum operating pressure is 125 psi with a peak flow of 10.8 gpm, so the pump fits systems that stay within those boundaries. Applications requiring higher pressure or greater volume need a different unit.

Questions about this item

How do I install the Dayton 41TK18 pump and what step is often missed?

Mount the pump securely, connect the 1/2 in intake, wire the 230/460V three-phase motor for the correct voltage, and prime the gear housing before starting — dry-running damages the Viton mechanical seal.

What maintenance or replacement will the Dayton 41TK18 need over time?

Inspect the Viton mechanical seal and steel spur gears periodically; replace the seal if leakage appears and the gears if wear reduces the 10.8 gpm flow rate at up to 125 psi.

What limit appears first when the Dayton 41TK18 runs continuously?

The 280 °F maximum operating temperature is typically the first sustained-use limit; exceeding it degrades the Viton seal and can cause pump failure.
