Dayton 41TK05 Rotary Gear Pump

The Dayton 41TK05 is a cast-iron rotary gear pump driven by a 1 hp single-phase motor. It moves fluid at up to 4.8 gpm against a maximum pressure of 125 psi and handles viscosities to 500 SUS. The pump accepts a 1/4 in inlet connection and is rated for media temperatures from 32 to 280 degrees F. A mechanical Viton seal and steel spur gears complete the assembly.

Suitable uses and limits

This pump suits applications needing steady flow at moderate pressure, such as lubrication circuits, fuel transfer or light hydraulic duties where the 1/4 in inlet matches the plumbing. It is not suited for systems requiring higher flow rates, larger inlet sizes or suction lifts beyond 3.5 ft. Buyers needing a different voltage, phase configuration or seal material should look at alternative models.

Capacity and headroom

The unit delivers a maximum flow of 4.8 gpm at 125 psi, providing headroom for typical low-volume transfer tasks. Viscosity is capped at 500 SUS, so heavier oils or cold-start conditions above that limit will reduce performance. The 3.5 ft suction lift restricts installation height relative to the fluid source, and the 1/4 in inlet may become a bottleneck if pipework is upsized downstream.

Highlights

  • Handles viscous fluids up to 500 SUS
  • Delivers up to 4.8 gpm flow rate
  • Operates at pressures up to 125 psi
  • Self-primes with 3.5 ft suction lift
  • Runs on 115/230V single-phase power

Questions about this item

What power supply do I need for the 1 hp motor rated at 115/230V AC single phase?

The motor runs on 115 V or 230 V AC single-phase power. Wire it to the matching voltage and provide a circuit rated for the motor's full-load current.

Will the 1/4 in inlet connect to my existing 1/4 in plumbing without adapters?

The pump has a 1/4 in media intake connection. If your existing line is also 1/4 in, it will mate directly; otherwise use the appropriate reducer or adapter.

How can I verify the pump is delivering up to 4.8 gpm after installation?

Install a flow meter or timed-volume test on the discharge side. At the rated speed and with fluid below 500 SUS viscosity, flow should approach 4.8 gpm.
