Rotary gear pump head with bronze body

This Dayton 4KHH1 rotary gear pump head features a bronze body and 1/4 inch NPT connections. It delivers a flow rate of 1.9 gpm at a maximum operating pressure of 100 psi. The unit is designed for integration with a compatible 1/3 hp motor.

Suits fluid-transfer systems needing bronze

This pump head suits installations requiring bronze material compatibility and a 1/2 inch shaft diameter. It is not for buyers who need a complete pump assembly with an integrated motor. It is not for systems exceeding a maximum viscosity of 550 SUS or a suction lift greater than 2.5 ft.

Maximum operating pressure of 100 psi

The pump head is rated for a maximum operating pressure of 100 psi, which determines its suitability for the intended plumbing circuit. The bronze body and Kevlar PTFE packing seal operate within a temperature range of -20 to 210 degrees F. Verify that your system pressure does not exceed this limit.

Questions about this item

How do I verify the pump head is delivering the rated 1.9 gpm at 100 psi after installation?

Use a calibrated flow meter and pressure gauge on the discharge line; the unit should reach 1.9 gpm at 100 psi with a 1/3 hp motor and fluid viscosity up to 550 SUS.

What components are included with the 4KHH1 pump head and what must be sourced separately?

The bronze pump head with 1/2 in shaft, 1/4 in NPT ports and Kevlar/PTFE packing is supplied; a compatible 1/3 hp motor, mounting hardware and piping are not included.

Which viscosity and temperature limits should guide my choice of this 1.9 gpm bronze gear pump head?

Select this model when your fluid stays below 550 SUS viscosity and between -20 °F and 210 °F, with a maximum suction lift of 2.5 ft and 100 psi operating pressure.
