  • TypeDrain Components
  • Delivers up to 4.4 gpm at 100 psi for strong flow
  • Handles fluids up to 550 SUS viscosity for versatile use
  • Operates reliably from -20 °F to 210 °F across wide temperature range
  • Withstands 125 psi maximum pressure for demanding applications
  • Bronze body with mechanical seal resists wear and prevents leaks

Product Purpose

The Dayton 4KHF3 is a bronze rotary gear pump head designed for fluid transfer applications requiring up to 125 psi operating pressure. It connects via 3/8 inch NPT fittings and operates within a temperature range of -20 to 210 degrees Fahrenheit. A 1 hp motor is required to drive the unit.

Suitable Applications

This pump head suits systems moving fluids with viscosity up to 550 SUS where a 4.4 gpm flow rate at 100 psi meets demand. It is not for installations needing a different connection size, a higher pressure rating, or a built-in motor. Buyers needing a complete pump assembly should look elsewhere.

Critical Specification

The 3/8 inch NPT connection size determines whether this head fits existing plumbing. Verify the port size before purchase to ensure compatibility with your piping system.

Questions about this item

Does the 4KHF3 pump head come with a motor, or must I supply a separate 1 hp unit?

The head requires a separate 1 hp motor; no motor is included in the box.

Which connection size matches my 3/8 in. NPT piping?

The 4KHF3 has a 3/8 in. NPT inlet and outlet, so it fits that piping directly.

What flow rate will I see at the rated 100 psi operating pressure?

At 100 psi the pump delivers 4.4 gpm with a maximum viscosity of 550 SUS.
