For most installations, the best replacement is the Pentair IntelliFlo3 VSF 3 HP 011075 or 011076. However, the correct model may depend on your automation system, equipment pad, electrical supply, plumbing, and desired control features.
Best Overall Replacement: Pentair IntelliFlo3 VSF 3 HP | 011075

It provides variable-speed and variable-flow operation, built-in smart connectivity, quiet performance, and strong circulation for residential in-ground pools. The pump operates from 450 to 3,450 RPM and is designed for 208–230V electrical systems.
Why choose the 011075?
- 3 HP variable-speed and variable-flow performance
- Built-in app connectivity
- Sensorless flow-control technology

Replacement With an I/O Relay Board: Pentair IntelliFlo3 VSF | 011076
The Pentair IntelliFlo3 VSF 011076 offers the same 3 HP variable-speed and variable-flow platform but includes an integrated I/O relay board.
The relay board provides additional control and integration options for compatible pool equipment. This model is often selected when the installation needs more equipment-control flexibility.
Choose the 011076 when:
- You need the integrated I/O relay board
- You want expanded equipment-control options
- Your system includes additional pool or spa equipment
- Your installer has confirmed the relay board is beneficial
- You want app connectivity and advanced pump programming

Replacement With a Touchscreen: Pentair IntelliFlo3 VSF | 011077
The standard IntelliFlo3 is primarily managed through connected controls and compatible Pentair applications. Customers who want a physical touchscreen directly on the pump should consider the Pentair IntelliFlo3 VSF 011077.
This model includes an integrated touchscreen while retaining 3 HP variable-speed and variable-flow performance, app connectivity, and compatibility with select Pentair automation systems.

Lower-Cost Alternative: Pentair WhisperFlo VST | 011533
The Pentair WhisperFlo VST 011533 can be a good alternative when the pool does not require every feature offered by the IntelliFlo3.
It is a 2.6 HP variable-speed pump designed for residential pool circulation. It supports 115V or 208–230V electrical input, which may make it suitable for installations where electrical flexibility is important.
Consider the WhisperFlo VST when:
- You want a lower-cost variable-speed pump
- Your pool does not require the full output of a 3 HP IntelliFlo3
- You need a pump that supports either 115V or 208–230V
- You do not require variable-flow operation
- Your installer confirms that its hydraulic performance is appropriate

Can You Repair the Pentair 011018 Instead of Replacing It?
A complete pump replacement may not be necessary if the existing pump housing and wet end remain in good condition.
The Pentair 350105S replacement motor is associated with older IntelliFlo VS-style pumps that use the earlier three-pin motor connection. Confirming the connector and existing drive configuration is essential before ordering.
A motor repair may make sense when:
- The pump housing is not cracked
- The wet end is not leaking
- The motor or bearings have failed
- The existing drive remains compatible
- Repair costs are substantially lower than full replacement
- The installer confirms the correct motor and drive configuration

Will the IntelliFlo3 Fit the Existing 011018 Plumbing?
The IntelliFlo3 is frequently used to replace older IntelliFlo pumps, but it should not be treated as a guaranteed drop-in replacement for every installation.
Before purchasing, confirm:
- Suction and return plumbing size
- Union and port alignment
- Available equipment-pad space
- Electrical voltage
- Breaker and wiring requirements
- Bonding requirements
- Automation-system compatibility
- Clearance for service and maintenance
Some installations may require plumbing adjustments, new unions, electrical modifications, or automation programming.
Which Replacement Should You Choose?
| Replacement option | Best for |
|---|---|
| IntelliFlo3 011075 | Most standard 011018 full-pump replacements |
| IntelliFlo3 011076 | Installations requiring an I/O relay board |
| IntelliFlo3 011077 | Customers wanting a pump-mounted touchscreen |
| WhisperFlo VST 011533 | Lower-cost residential variable-speed applications |
| 350105S motor | Repairing certain older IntelliFlo VS pump assemblies |
For most pool owners replacing a complete Pentair 011018, the IntelliFlo3 VSF 011075 is the best starting point.
