Pentair 342002 SuperFlo VST Variable-Speed In-Ground Pool Pump, 2.2 THP

The Pentair 342002 SuperFlo VST is a high-efficiency variable-speed pool pump designed for residential in-ground pools requiring up to a 1.5 HP-class pump. With 2.2 total horsepower, flexible 115V or 230V operation, programmable speed settings, onboard scheduling, and RS-485 connectivity, it is an excellent upgrade from older single-speed or two-speed pool pumps.

2.2 THP Variable-Speed Motor 115V / 230V Compatible WEF 9.0 at 230V RS-485 Automation Ready

Energy-Saving Variable Speed

Run lower RPMs for daily filtration, then increase speed only when needed for vacuuming, heating, water features, or backwashing support.

SuperFlo Retrofit-Friendly Design

Designed as a replacement path for existing Pentair SuperFlo installations and many Hayward Super Pump replacements where plumbing and pad space are compatible.

Simple Built-In Controls

The onboard digital keypad includes programmable speed settings, a 24-hour clock, and manual override capability for straightforward everyday operation.

Why Upgrade to the Pentair SuperFlo VST?

Older single-speed and two-speed pumps operate at fixed RPMs, often consuming more energy than the pool needs for routine circulation. The SuperFlo VST gives pool owners the ability to match pump speed to the task, reducing unnecessary electrical use while maintaining dependable filtration, heating circulation, and water quality.

  • Variable-speed operation supports lower-energy daily filtration schedules.
  • 2.2 THP performance for standard residential in-ground pool applications.
  • Three programmable speed settings plus manual override capability.
  • Real-time 24-hour clock helps simplify pump scheduling.
  • Improved mechanical seal designed for long-term durability.
  • RS-485 connectivity supports improved compatibility with select automation systems and connected devices.
  • Designed as a replacement option for existing Pentair SuperFlo pumps and many Hayward Super Pump installations.
Replacement Upgrade Note: The Pentair 342002 is a strong current upgrade path for older SuperFlo single-speed and two-speed pumps, including discontinued models such as the Pentair 340042 SuperFlo 1 HP, 230V two-speed pump. It is variable speed, so it should be programmed for the pool's actual hydraulic needs rather than operated as a fixed high-speed replacement.

Installation & Replacement Compatibility

The SuperFlo VST is commonly used to replace older Pentair SuperFlo pumps and other standard residential in-ground pool pumps. Confirm electrical service, plumbing orientation, union compatibility, available pad space, and required flow before ordering.

  • Verify whether the existing pump is wired for 115V or 230V before installation.
  • For replacement of a 230V two-speed pump, the SuperFlo VST should generally receive constant 230V power and operate from its onboard schedule or compatible automation controls.
  • Do not use an old two-speed timer or switch to attempt to control pump speeds.
  • Confirm plumbing size, union location, suction/discharge orientation, and equipment-pad clearance.
  • Check total system demand when operating heaters, salt systems, water features, suction cleaners, or spa spillovers.
  • Program lower daily filtration speeds first, then increase RPM only as needed for specific equipment or water features.

Pump selection should be based on hydraulic requirements, not motor horsepower alone. Higher THP does not mean the pump must run at high speed during normal filtration.

Frequently Asked Questions

Is the Pentair 342002 a good replacement for an older SuperFlo two-speed pump?
Yes. The 342002 SuperFlo VST is a strong modern replacement path for many older SuperFlo single-speed and two-speed pumps. Confirm voltage, plumbing orientation, available equipment-pad space, and system flow requirements before ordering.
Can this pump run on 230V?
Yes. The Pentair 342002 can operate on 115V or 208–230V power. It delivers its highest listed WEF rating when wired for 230V.
Does the SuperFlo VST have a built-in timer?
Yes. It includes an onboard digital control keypad with programmable speeds, manual override capability, and a real-time 24-hour clock for daily scheduling.
Can I use my old two-speed switch with this variable-speed pump?
No. A variable-speed pump should not be controlled through an old high/low-speed switch. It should receive proper constant power and be operated through its keypad, programmed schedule, or compatible automation interface.
Is this pump compatible with pool automation?
The SuperFlo VST includes RS-485 connectivity for improved communication with compatible automation systems and connected devices. Confirm compatibility with the specific control system before installation.
What plumbing size does the pump use?
The pump uses 1-1/2 inch slip and 2 inch spigot union-style plumbing connections. Always compare the existing union spacing and pipe orientation before ordering.
