Pentair SuperFlo VS Pumps
The SuperFlo VS pump product line are variable speed 1.5HP pumps rated at WEF 9.0 THP 2.2 that can run on 120 volts or 240 volts. These VS pumps are a direct replacement for Pentair SuperFlow pumps and the Hayward Super Pump.
In the SuperFlo VS product line there is the SuperFlo VS pump manufactured before 11/20/2020 which does not have RS-485 communication ability and the SuperFlo VST, SuperFlo VS, and Sta-Rite Supermax pumps manufactured after 11/20/2020 that have RS-485 communication ability.
SuperFlo versus IntelliFlo
If you need the pump to run on 120 volts or want a direct replacement for a Superflow or Hayward Super Pump then the SuperFlo VS pump is the right pump for you.
An IntelliFlo VS/VSF pump will be more efficient and use less electricity at the equivalent HP then a SuperFlo VS pump. Let's say your pool needs .75 HP of water flow. The 1.5 HP Superpump VS will run at about half speed of 1750 RPM while the 3 HP IntelliFlo will be able to run at .75 HP at 1000 RPM or less. 1000 RPM on the IntelliFlo will use less electricity then 1750 rpm on the SuperFlo VS.
Consider the compatibility you need with any automation.
Pentair Automation Compatibility
The SuperFlo VS and Supermax VS pumps manufactured after 11/20/2020 with RS-485 communication can digitally communicate with IntelliCenter, IntelliSync, EasyToucn, and IntelliTouch systems.
The SuperFlo VS pumps manufactured before 11/20/2020 can connect to automation systems using an external low voltage control and a relay for each speed.
The Pentair IntelliSynch will provide wireless app control for all SuperFlo VS pumps through the RS-485 inputs or external low voltage inputs.
The SuperFlo VS will not connect by RS-485 with a Pentair IntelliConnect system.
SuperFlo VS Communications Cable
The SuperFlo VS pump has an 8 pin proprietary connector on the side for the communication cable. It is different then the 7 pin connection used in the IntelliFlo pumps and the cables are not interchangeable.[1]
The pre 11/20/2020 SuperFlo VS without RS-485 used Pentair Wiring Kit 353129Z with wires in six of the eight pins. Pentair Wiring Kit 353129Z is now obsolete and is replaced by Wiring Kit 356324Z with wires connecting all eight pins.
The pumps with RS-485 ability use Wiring Kit 356324Z with wires connecting all eight pins.
If you get the 356424Z SuperFlo VS to Automation Cable package it will contain the following labels:
Note how the cable wiring colors have changed for connection to the IntelliSynch depending on which cable is used. The green and yellow wires changed to white and blue since green and yellow are the standard colors used for the RS-485 data wires.
The SuperFlo VS automation cables have not been widely available and some members have figured out how to build them. A M12 (12mm) "aviation plug" was tried and was too small. What did fit with some dremerling is a "GX16" - 16mm "aviation plug".
The pinout of the 353129Z cable for the pre 11/20/2020 SuperFlo VS pump From the notched edge going clockwise is:
- Center - Black
- 1- red
- 2- empty
- 3- empty
- 4- green
- 5- yellow
- 6- orange
- 7- brown
The cable connector looks like:
Another member couldn't find a compatible connector off the shelf but after looking at the back of the existing connector to check, it's just terminated from the loose wires coming out of the controller module anyway. So he bought a standard GX16 connector kit and just cut off the proprietary/mystery Pentair port and reterminate the wires onto the GX16 port (which fits the same hole in the cover). He felt his time soldering this together may not have been worth the ~$40-50ish for the Pentair solution if it was available but it's certainly worth $200 for a simple cable.
SuperFlo VS losing Clock with Power Loss
A members Pentair SuperFlo VS - 342001 - would lose its clock when the power was lost. He found there is a super capacitor on the key pad module that keeps power for 24 hours for the clock.
Specifically c26 on the cover board as can see on the pictures below is a ELNA 3.3V 0.33F, Part Number DSK-3R3H334U-HL. It is s on the driver cover/display, so not so difficult to replace. It can be ordered from Digikey for $2 + shipping,[2]
These small super capacitors are very sensitive to the soldering temperature. Hold the legs of the capacitor with a tweezers while soldering which reduces a lot of the heat received by the capacitor... see some pictures as example how to minimize the temperature during soldering
