Hayward Super II Eco 1.25 HP Pool Pump (1B-SP3012DI)

The Hayward Super II Eco — part no. 1B-SP3012DI — is a 1.25 HP single-speed pool pump designed for new pool construction and as a high-performance upgrade for medium-head pump installations. Full-flow hydraulics deliver greater water flow at a lower cost of operation, while the heavy-duty motor with airflow ventilation runs quieter and cooler for extended motor life.

The large 155 cubic-inch strainer basket extends the time between cleanings, and the uni-bracket mounting base adapts to both 48- and 56-frame motors for versatile installation.

Frequently Asked Questions

What is the difference between the Hayward Super II and Super II Eco?

The Super II Eco is the current generation of Hayward’s Super II pump range, featuring updated full-flow hydraulics and an energy-efficient motor design that delivers greater flow at a lower cost of operation compared to older medium-head pump designs. The “Eco” designation reflects the improved efficiency of the motor and hydraulic design.

Is the Super II Eco suitable as a replacement for my existing pump?

The Super II Eco is designed as an upgrade path for medium-head pool pumps and is suitable for most standard residential pool filtration systems. The uni-bracket mounting base adapts to both 48- and 56-frame motors, making it compatible with a wide range of existing pump bases. Check your current pump’s HP rating and plumbing connection sizes before ordering to confirm suitability.

How often does the strainer basket need cleaning?

The 155 cubic-inch strainer basket is larger than most standard pump baskets, which extends the time between cleanings. In normal conditions, check and clean the basket weekly or whenever you notice reduced flow or suction. During high-debris periods (autumn, after storms), check more frequently.

What does full-flow hydraulics mean?

Full-flow hydraulics refers to the pump’s internal impeller and volute design, which is optimised to move a higher volume of water with less resistance (head loss) compared to standard medium-head pump designs. This means the pump can achieve the same or greater flow rate while consuming less energy, reducing operating costs over time.
