Recirculating Pump Comparison Guide
Voltage and Power
The Moonshan 3-Speed Stainless Steel Circulator Pump operates on 110V with a 120V attribute listing, offering three adjustable power settings: 46W, 85W, and 100W. This flexibility allows you to match the energy draw to your specific system requirements. The Moonshan Recirculating Pump with Stainless Sensor Valve does not list its voltage or wattage in the provided data. Because the first pump provides clear power options and specific wattage figures, it gives you more control over energy consumption and electrical compatibility. The second pump’s electrical specs remain undefined in this dataset.
Flow Rate and Head
Performance metrics differ significantly between these two units. The 3-Speed Stainless Steel Circulator Pump delivers a maximum flow rate of 13 GPM and can push water up to a head of 26 ft. These numbers indicate it can handle larger systems or longer pipe runs effectively. The Recirculating Pump with Stainless Sensor Valve does not provide flow rate or head pressure data in its specifications. Without these figures, you cannot gauge its capacity for your home’s plumbing layout. The first pump’s published performance metrics make it the clearer choice for understanding hydraulic capability.
Control Type
You have different ways to manage when the hot water runs. The 3-Speed Stainless Steel Circulator Pump uses a manual 3-speed control switch, letting you adjust the intensity directly on the unit. The Recirculating Pump with Stainless Sensor Valve features a programmable timer control. This intelligent timer lets you set specific start and stop cycles, ensuring hot water is available during your wake-up or dinner times without manual adjustment. The programmable nature of the second pump offers more automation for daily convenience compared to the manual switching of the first.
Compatibility
These pumps are designed for different heater types. The 3-Speed Stainless Steel Circulator Pump is compatible with standard water heaters, boilers, solar systems, and hydronic heating setups, making it versatile for various heating sources. The Recirculating Pump with Stainless Sensor Valve is explicitly designed for indoor use with standard tank water heaters only. It is not compatible with tankless water heaters. If you have a boiler or solar system, the first pump is the only viable option. For a standard tank heater, both work, but the first offers broader applicability.
Installation Kit
Both kits include necessary parts for setup, but the components differ. The 3-Speed Stainless Steel Circulator Pump includes 1-inch FNPT flanges, gaskets, nuts, and bolts. This suggests a more robust, possibly permanent plumbing connection using standard pipe threads. The Recirculating Pump with Stainless Sensor Valve comes with a sensor valve, 20-inch PEX food grade supply lines, adapters, and Teflon tape. The PEX lines and sensor valve suggest a simpler, under-sink bypass installation. The first pump’s kit is suited for hard piping, while the second is tailored for quick PEX connections.

Frequently asked questions
Can I use the Moonshan 3-Speed pump with a tankless water heater?
No. The Moonshan RSF-5 is designed for boiler systems, not tankless units. Its specifications list the use as boiler. You need a recirculating pump specifically rated for tankless heaters to ensure proper flow and temperature control. Using this pump with a tankless system may cause performance issues or damage.
What is the difference between the Moonshan MS-ZN-20 and the RSF-5?
The MS-ZN-20 includes a timer for scheduled operation, while the RSF-5 offers manual speed control. The RSF-5 has three adjustable power settings. The MS-ZN-20 is built for standard tank water heaters. Both use stainless steel, but their control methods and target systems differ significantly for your plumbing setup.
Does the Moonshan recirculating pump come with a sensor valve?
The Moonshan MS-ZN-20 includes a stainless sensor valve. The RSF-5 model does not list this feature in its specifications. If you need automatic activation based on water temperature, the MS-ZN-20 is the better choice. The RSF-5 relies on manual speed adjustments for operation.
How loud is the Moonshan 3-Speed Circulator Pump?
The product data does not specify decibel levels for the RSF-5 pump. It offers three speed settings to adjust power usage. You can select a lower speed for quieter operation. The MS-ZN-20 also lacks noise specifications in the provided data. Check the manufacturer manual for sound ratings if quiet operation is critical.
What voltage does the Moonshan recirculating pump require?
Both pumps operate on 110V or 120V circuits. The RSF-5 is listed with a 120V attribute. The MS-ZN-20 is also designed for standard household voltage. You do not need a special transformer. Ensure your home has a standard 110V-120V outlet near the installation point for either model.
Is the Moonshan pump made of stainless steel?
Yes. Both the RSF-5 and MS-ZN-20 use stainless steel for durability. The RSF-5 is described as a stainless steel circulator. The MS-ZN-20 also features stainless steel components. This material resists corrosion and extends the life of the pump in wet environments like utility rooms or basements.
Can I install the Moonshan pump myself?
The data does not provide installation instructions. Both units are compact, with the RSF-5 measuring 7.87 inches in length. The MS-ZN-20 weighs 6 pounds. You should consult a licensed plumber for proper integration into your hot water system. Incorrect installation can void warranties or cause leaks.
What is the flow rate of the Moonshan MS-ZN-20?
The provided data does not list the flow rate for the MS-ZN-20. It only specifies the model and material. The RSF-5 data also lacks explicit flow rate details in the specs. You may need to contact the manufacturer or check the full product manual for GPM ratings before purchasing.
