Specifications

Energy-Efficient Single-Speed Design

The EC-348190 combines the simplicity of a traditional single-speed pump with a modern NEMA Premium Efficient motor. Pentair lists the pump with a WEF rating of 3.6, helping it satisfy applicable federal efficiency standards while maintaining the straightforward operation many pool systems require.

Unlike a variable-speed pump, this model operates at one fixed motor speed. Pump runtime is normally controlled by:

• Mechanical pool timer
• Digital timer
• Automation relay
• Approved external control system
• Properly rated electrical disconnect

Ideal For

• Residential in-ground swimming pools
• Pool-and-spa combinations
• New pool construction
• Replacement of older SuperFlo pumps
• Replacement of select Hayward Super Pump installations
• Standard filtration systems
• Pool systems using mechanical or digital timers
• Applications requiring a DOE-compliant single-speed pump
• Installations with 1.5-inch or 2-inch plumbing

Benefits

• NEMA Premium motor provides improved single-speed efficiency
• TEFC construction helps protect the motor from outdoor contaminants
• Dual-voltage capability supports a variety of equipment-pad configurations
• Quick-disconnect unions simplify removal and servicing
• Clear lid allows debris inspection without opening the pump
• Large basket helps extend intervals between cleaning
• Quarter-turn lid provides convenient basket access
• Self-priming design supports standard in-ground installations
• Balanced hydraulics help reduce operating noise
• Common plumbing dimensions simplify replacement projects
• DOE-compliant design replaces older noncompliant single-speed models

What’s Included

• Pentair SuperFlo 1.1 THP pump assembly
• NEMA Premium Efficient TEFC motor
• Pump housing and wet end
• Strainer basket
• Clear Cam and Ramp lid
• Lid O-ring
• Quick-disconnect union fittings
• Drain plugs
• Motor base
• Installation and operating documentation

Electrical wiring, circuit breaker, timer, automation relay, plumbing pipe, valves and installation materials are not included unless specifically stated by the seller.

Plumbing Connections

The SuperFlo pump uses combination connections designed to accommodate:

• 1.5-inch internal slip plumbing
• 2-inch external slip plumbing

Pentair includes quick-disconnect plumbing unions to help reduce service time when the pump must be removed from the equipment pad.

The suction plumbing should be the same size as or larger than the return plumbing. Pentair recommends keeping the suction line as short and direct as practical to reduce hydraulic resistance.

Replacement Compatibility

The SuperFlo is designed for common residential pool-pump installations and may serve as a replacement for:

• Existing Pentair SuperFlo pumps
• Select Sta-Rite SuperMax configurations
• Many Hayward Super Pump installations
• Other pumps with compatible plumbing heights and performance requirements

Pentair describes the SuperFlo as a high-performing drop-in replacement option for the Hayward Super Pump. Plumbing, voltage, pump dimensions and hydraulic requirements must still be confirmed before installation.

Strainer-Basket Maintenance

Inspect the pump basket regularly through the clear lid. Pentair recommends visually inspecting the basket at least weekly because accumulated debris can reduce circulation efficiency and place additional stress on the pump motor.

Before opening the pump:

1. Turn off power at the circuit breaker.
2. Prevent the pump from restarting automatically.
3. Close isolation valves when required.
4. Open the filter air-relief valve.
5. Confirm that all system pressure has been released.
6. Remove the lid and clean the basket.
7. Inspect and lubricate the lid O-ring with an approved pool lubricant.
8. Refill the pump housing with water before restarting.
9. Reinstall the lid securely.
10. Open all valves and properly bleed air from the system.

Never operate the pump without the basket installed.

Installation Requirements

This pump should be installed and serviced by a qualified pool professional in accordance with applicable electrical, plumbing and safety codes.

Installation requirements include:

• GFCI-protected electrical circuit
• Correct voltage selection
• Proper equipment grounding
• Proper bonding to the pool bonding grid
• Correctly sized wiring and overcurrent protection
• Secure, level equipment pad
• Adequate ventilation around the motor
• Approved suction fittings and drain covers
• Properly sized suction and return plumbing
• Sufficient access for future maintenance

Pentair requires the pump to be connected to a GFCI-protected circuit and installed according to the National Electrical Code and applicable local requirements.

Important Operating Information

• This is a single-speed pump, not a variable-speed pump.
• The pump is not submersible.
