Rotary gear pump head with bronze body and 3/8 in. NPT connections delivers up to 6.5 gpm at 100 psi

  • TypeDrain Components
  • Delivers up to 6.5 gpm flow at 100 psi for efficient fluid transfer
  • Handles viscous media up to 550 SUS with spur gear design
  • Operates reliably from -20 °F to 210 °F across demanding environments
  • Self-primes with 7.9 ft suction lift for flexible installation
  • Bronze body with Kevlar PTFE packing resists wear and chemical attack

Pump Head Purpose

The Dayton 4KHG6 is a rotary gear pump head designed for fluid transfer in industrial and commercial plumbing systems. It connects via a 3/8 inch NPT port and operates with a bronze body and spur gear design. The unit requires a 1 1/2 hp motor input and uses a packing seal made from Kevlar and PTFE.

Suitability And Limits

This pump head suits operators who need a bronze-bodied gear pump for viscosities up to 550 SUS and pressures up to 100 psi. It is not for buyers who need a different connection size, a higher flow rate than 6.5 gpm at 100 psi, or a seal material other than Kevlar and PTFE packing.

Sustained Operation Behaviour

Under continuous load the pump head handles temperatures from -20 to 210 degrees F and maintains a maximum suction lift of 7.9 ft. The bronze construction and spur gears deliver steady flow at the rated 6.5 gpm while the packing seal manages shaft wear during extended duty cycles.

Highlights

  • Delivers up to 6.5 gpm flow at 100 psi for efficient fluid transfer
  • Handles viscous media up to 550 SUS with spur gear design
  • Operates reliably from -20 °F to 210 °F across demanding environments
  • Self-primes with 7.9 ft suction lift for flexible installation
  • Bronze body with Kevlar PTFE packing resists wear and chemical attack

Questions about this item

What motor horsepower is required to drive this 3/8 in. rotary gear pump head?

The pump head requires a 1 1/2 hp motor to operate at its rated performance.

Can the bronze body and Kevlar PTFE packing handle fluid temperatures near the 210 °F upper limit?

Yes, the bronze construction and Kevlar PTFE seal material are rated for continuous operation up to 210 °F and down to -20 °F.

After installation, how can I confirm the pump is delivering the rated 6.5 gpm at 100 psi?

Measure the outlet flow with a calibrated flow meter while a pressure gauge reads 100 psi; the flow should be 6.5 gpm.
