Product Description

Power-Flo Matrix Above-Ground Pump Series

The Big news in above-ground pumps is the PowerFlo Matrix by Hayward. It features an industrial-size strainer basket to collect a lot of debris without a lot of maintenance.

The high-quality Noryl impeller offers wide openings to prevent leaf and debris clog. While this pump is impressively equipped, the PowerFlo Matrix is also very efficient. It has a heat-resistant, double-size seal and a protected rear-mounted switch for high-energy efficiency. Plus, its heavy-duty, high-performance motor provides years of trouble-free operation thanks to an integrated automatic thermal overload protector. PowerFlow Matrix clearly the superior choice in above-ground-pool pumps.

The Power-Flo Matrix has been engineered as a uniquely superior above-ground pool pump. With a single push of a button, this truly versatile pump changes from a veritical to a horizontal discharge and back again. Its large profile and integrated styling makes the Power-Flo Matrix a swimming pool pump like no other.

How many gallons per minute & what hp do I need for a 24000 gal. Pool & what size D E filter would be compatible?

A  Answered on 3/16/2015 by InyoPools Product Specialist Lennox H.

Hayward Matrix pool pump is for an above ground pool, is your pool above or inground? I would also need to know your pipe size if you do have an inground pool.

We would recommend the Hayward EC50C93S. The pump would come with a standard 3-prong plug.

Will this pump accommodate salt water ?

A  Answered on 5/13/2015 by InyoPools Product Specialist Brian M.

Any pool pump can accommodate a salt system ( water ) The most damaging thing to a pump would be if the water gets out of balance. Or if an object made it past the pump basket and damaged the impeller.
