Feel free to get in touch
The Jandy R0974401 Variable Speed Drive is the genuine Zodiac/Jandy OEM replacement drive unit for 1.85 HP FloPro and VS-series DV2A variable-speed pumps. When the drive fails but the motor and wet end remain sound, this restores full variable-speed control — programmable RPM, scheduling, and energy-efficient operation — without replacing the entire pump.
Key Features

Frequently Asked Questions
What pump does the Jandy R0974401 fit?
The 1.85 HP DV2A variable-speed platform — VS FloPro models ending in 185DV2A (and their "S" variants). Confirm the model number on your motor label before ordering.
What's the difference between R0974401 and R0974400?
Horsepower. The R0974401 is the 1.85 HP drive; the R0974400 is the 2.7 HP drive. They pair with different motors and are not interchangeable — match the drive to your pump's HP rating.
Does this include the controller?
No — drive only. It's intended for systems that already have a SpeedSet controller or run the pump through automation.
Is it 115V or 230V?
Both — a dual-voltage unit that works with 115V and 230V systems.
When should I replace the drive instead of the whole pump?
When the drive has failed — erratic RPM, startup faults, error codes, or no power to the motor — but the motor and wet end are still good. Replacing just the drive is far cheaper than a full pump.
Should a professional install it?
Yes. This is a high-voltage component — disconnect power first, mount with OEM fasteners, keep waterproof seals intact, and reprogram RPM schedules after installation. Installation by a qualified pool professional is recommended.
Frequently asked questions
Is a variable speed pump worth it?
Variable speed pumps draw dramatically less power at low speed because energy use falls far faster than flow does. Many jurisdictions now require variable speed for new and replacement residential pool pumps above a certain horsepower, so check local code before buying single-speed.
What is the part number for this pump?
Jandy lists this pump under part number R0974401. Quote R0974401 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
How do I match a pump to my pool?
Work from the plumbing rather than the pool size: line diameter, total dynamic head and the flow your filter and heater can accept all cap the useful pump size. An oversized pump on undersized plumbing wastes power and can exceed the filter's rated flow.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Jandy equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
What do I need to check before installing this pump?
Confirm the voltage, the union or port sizes and the mounting footprint against your existing installation. Pump replacement usually involves electrical connections and may require a licensed electrician depending on local requirements.
Is there a warranty on this pump?
It carries the standard Jandy manufacturer warranty. The terms are set by Jandy, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
