Pump head for 56C frame motors

The Dayton 4KHC2 is a bronze rotary gear pump head designed to couple directly with a 56C frame motor. It delivers a flow rate of 10.2 gpm at 100 psi and handles viscosities up to 550 SUS. The unit operates between -20 and 210 degrees F at a maximum pressure of 125 psi.

Suits transfer of lubricating fluids.

This pump head suits installations moving oils or similar lubricating liquids where a bronze body and Buna-N mechanical seal are compatible. It is not for potable water systems or aggressive chemicals that attack bronze. Buyers needing a self-priming lift above 12.3 ft should look elsewhere.

10.2 gpm at 100 psi determines fit

The rated flow of 10.2 gpm at 100 psi is the single figure that decides whether this head matches the system demand. Verify the required horsepower of 1 1/2 hp and the 1/2 in NPT connection size against the motor and piping before purchase.

Questions about this item

How often will the Buna-N, carbon, ceramic, stainless steel mechanical seal need replacement?

The mechanical seal uses Buna-N, carbon, ceramic and stainless steel faces; replacement interval depends on fluid abrasiveness and duty cycle, so inspect at each scheduled maintenance.

At 10.2 gpm and 125 psi, will the 1 1/2 hp motor requirement become the limiting factor?

The pump head is rated for 10.2 gpm at 100 psi and a maximum of 125 psi, requiring a 1 1/2 hp motor; sustained operation at peak pressure will load the motor to its rated capacity.

How hot does the bronze body get when running continuously at 210 °F fluid temperature?

The bronze housing will approach the fluid temperature of 210 °F during continuous operation, so external surfaces become too hot to touch and require guarding or insulation.
