Grundfos 00599378 Cartridge Assembly
The Grundfos 00599378 Cartridge Assembly is a high-performance 115V replacement kit engineered specifically for UPS15-58F/FR circulator pumps. This OEM Grundfos pump part is the standard professional solution for restoring flow efficiency in closed-loop hydronic heating and cooling systems without replacing the entire cast iron or bronze pump housing. Designed for a 1/25 HP motor profile, this replacement cartridge assembly features a durable stainless steel and PES composite construction that handles system debris and high-temperature water circulation with minimal mechanical wear.
For contractors, the Grundfos 599378 cartridge kit ensures a precise fit and rapid field service, eliminating the need for specialized tools during the swap. By replacing the wet-rotor cartridge, you effectively renew the impeller, shaft, and bearings, resolving common issues like seized rotors, noisy operation, or reduced head pressure. This assembly is rated for standard residential and light commercial HVAC applications where consistent GPM delivery and whisper-quiet performance are non-negotiable.
- Direct OEM Compatibility: Specifically balanced for Grundfos UPS15-58F and FR series pumps to ensure hydraulic performance matches original factory specifications.
- Reduced Downtime: The drop-in design allows for a clean motor-end replacement, keeping the existing piping intact.
- Corrosion Resistance: Engineered with a stainless steel rotor cladding and axial bearing system to withstand aggressive water conditions.
- Optimized Efficiency: Restores peak electrical and mechanical efficiency to the circulator pump, lowering system operational costs.
Common Questions:
Which pump models use the Grundfos 00599378?
This cartridge is the dedicated replacement for the three-speed UPS15-58F and UPS15-58FR models. It is frequently used in boiler secondary loops, radiant floor heating, and indirect water heater circuits.
How can I tell if my cartridge needs replacement vs. the whole pump?
If the motor is receiving 115V power but the pump is humming or the shaft is seized, the cartridge internal bearings or impeller are likely worn. Replacing the assembly is the most cost-effective method to restore full function.
Is the gasket included with this cartridge assembly?
Yes, professional kits generally include the necessary O-ring or housing gasket to ensure a leak-proof seal during reassembly of the power head to the pump body.
