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.
