Benefits

The Pentair 356878Z helps restore control and operation on compatible IntelliFlo and IntelliPro variable-speed pumps. When the drive fails, the pump may not start, may lose programming, may display communication or drive errors, or may fail to run the motor at the correct speeds.

Replacing the drive can be a cost-effective repair when the pump wet end and motor are still in good working condition. Using a genuine Pentair OEM drive helps maintain proper communication, programming, and compatibility with supported Pentair pump platforms.

Specifications

Customer-Facing Q&A

What does the Pentair 356878Z do?
The 356878Z is the replacement drive module for compatible Pentair IntelliFlo and IntelliPro variable-speed pumps. It controls pump speed, programming, motor operation, and communication functions.

Is this a complete pump?
No. This is the drive assembly only. It does not include the complete pump, motor, wet end, seal plate, impeller, unions, or plumbing components.

Does this include the keypad/display?
Many current listings state that the 356878Z drive kit does not include the keypad. Confirm package contents before publishing or ordering. If the keypad is needed, it may need to be ordered separately.

Which pumps does this fit?
This part is commonly listed for select IntelliFlo VS, IntelliFlo VST, IntelliFlo i1/i2, IntelliFloXF, and IntelliPro VS pump models. Always confirm the existing drive part number and pump model before ordering.

Can this be used on every IntelliFlo pump?
No. IntelliFlo pumps have used different drives depending on model, generation, manufacture date, and pump type. This should not be ordered based on the IntelliFlo name alone.

Will this fix a pump that will not start?
It may help if the failure is caused by the drive. A no-start issue can also be caused by incoming power, wiring, keypad, motor failure, moisture damage, automation wiring, or other electrical issues. Proper troubleshooting is recommended.

Can homeowners install this themselves?
No. This is an electrical pump control component. Installation should be performed by a qualified pool professional or licensed electrician familiar with Pentair variable-speed pumps.

Confirm Before Ordering

Confirm the following before purchasing:

Part number: 356878Z
Pump series: compatible IntelliFlo or IntelliPro variable-speed pump
Pump model: verify exact model number from pump label
Drive type: VS/VST-compatible replacement drive
Manufacture date: compatibility may vary by generation
Keypad: confirm whether keypad is included or required separately
Electrical: professional installation required

Do not order based on pump appearance or the IntelliFlo name alone. Drive compatibility depends on exact pump model, existing drive part number, motor type, software/generation, and manufacture date. Electronic pump parts are typically not returnable once installed or opened.
