Hoffman 007-039RP Rotor Cartridge Assembly

Product Description

The HOFFMAN 007-039RP is a rotor cartridge assembly with an iron body, designed as a serviceable internal component for circulator pumps used in hydronic heating and cooling systems. This cartridge assembly houses the rotor and bearing components that drive fluid circulation through closed-loop piping systems. The iron body construction provides durability in wet-rotor pump applications. HVAC technicians and plumbers install this assembly during pump service or rebuild, replacing worn rotor components without swapping out the entire pump unit.

This rotor cartridge assembly is suited for residential and light commercial hydronic systems, including hot water heating loops and chilled water applications. It is a service replacement part installed when a circulator pump exhibits reduced flow, noise, or bearing failure. Technicians performing pump rebuilds on iron-body circulator pumps rely on this assembly to restore original pump performance.

Key Features

• Iron body construction for durability in hydronic wet-rotor pump service
• Rotor and cartridge assembly format enables in-field pump rebuild without full unit replacement
• Designed as a direct service replacement for compatible circulator pump bodies
• Reduces material cost by allowing cartridge swap rather than complete pump changeout

Compatibility

Designed as an OEM-style replacement rotor cartridge for iron-body circulator pumps. Confirm fitment against the installed pump model before ordering.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber. Shut down the system and allow it to fully depressurize and cool before disassembling the pump. Follow the pump manufacturer's service documentation for cartridge removal and installation procedures. Verify all seals and connections are properly seated before returning the system to operation.
