Critical Electrical Information

This Is a Three-Phase Pump

Model 345079 requires compatible three-phase electrical service. It is not designed to connect directly to a standard 230V single-phase residential pool-pump circuit.

Before selecting a replacement, verify the existing supply voltage, phase, breaker or motor protection, conductor sizing, grounding, bonding and equipment-control arrangement.

A replacement pump labeled 3 HP is not automatically compatible. Horsepower alone does not confirm electrical or hydraulic suitability.

Replacement and Retrofit Guidance

Pentair does not identify a direct drop-in supersession for model 345079. A replacement must be selected using the complete operating requirements of the pool or water system.

  • Confirm whether the existing service is 208V, 230V or 460V
  • Confirm whether three-phase power must be retained
  • Match the required flow rate and total dynamic head
  • Review filter, heater and water-feature flow limitations
  • Compare suction and discharge centerline dimensions
  • Allow for replumbing if the replacement footprint differs
  • Verify automation or external-control compatibility
A 230V single-phase variable-speed pump may be considered only when a qualified installer confirms that compatible single-phase electrical service is available and that the replacement pump meets the required hydraulic performance.

Frequently Asked Questions

Is Pentair Max-E-Pro 345079 still available?

No. Pentair Max-E-Pro model 345079 has been discontinued and is no longer available as a complete new pump through Aqua Terra Backyard. This listing remains online for identification and reference.

Is model 345079 a single-phase or three-phase pump?

It is a three-phase pump. It was manufactured for 208-230V or 460V three-phase electrical service.

Is this a variable-speed pool pump?

No. Pentair 345079 is a single-speed pump. Any conversion to a variable-speed model requires verification of electrical, hydraulic, plumbing and control compatibility.

Can a 230V single-phase pump directly replace 345079?

Not directly. Model 345079 is three phase, while most residential 230V variable-speed pumps are single phase. An electrician must verify or provide the correct electrical supply before a single-phase pump can be considered.

Does another 3 HP pump automatically match this model?

No. Two pumps carrying the same nominal horsepower can have different phase requirements, voltages, flow curves, service factors, port locations and plumbing dimensions.

What size plumbing connections does this pump use?

Pentair lists model 345079 with 2-inch suction and 2-inch discharge connections. Replacement-pump dimensions and union styles must still be compared before installation.

What is the original replacement motor number?

Pentair's replacement-parts documentation identifies motor 354812S for Max-E-Pro pump model 345079. Availability of individual service parts should be confirmed before ordering.

Will replacing this pump require replumbing?

Possibly. Replumbing is typically required when the replacement pump's suction height, discharge position, union style or overall footprint differs from the original Max-E-Pro.

How should a replacement pump be selected?

Selection should be based on available voltage and phase, required flow, total dynamic head, plumbing size, equipment-pad dimensions and any automation or water-feature requirements.

Need Help Identifying a Replacement Pump?

Before selecting a replacement, gather a clear photo of the motor nameplate, the available electrical service, existing plumbing size and the pool or water-feature operating requirements.
