Hayward Strainer Cover Replacement for Power-Flo Matrix SP1590 Series — SPX5500D with Lock Ring & O‑Ring

Replacement strainer cover for Hayward Power-Flo Matrix pumps that includes the lock ring and lid o-ring for a secure, leak-resistant fit.

If your above-ground pool pump needs a new lid, the Hayward SPX5500D strainer cover is made to restore proper sealing and reliable debris capture for Power-Flo Matrix SP1590 series pumps. Designed to match factory specifications, this replacement cover fits several Hayward pump and filter models so you can avoid downtime and maintain circulation without buying a whole pump. The part arrives complete with the lock ring and the rubber lid o-ring, saving you a separate shopping trip for complementary components.

Which pump and filter models will this strainer cover fit?

This cover is engineered to work with Hayward Power-Flo Matrix SP1590 series pumps, specifically SP1591, SP1592, SP1592FT and SP1593. It is also compatible with select Hayward cartridge and D.E. filters, and certain sand filter models, so one part covers multiple repair scenarios.

• Fits Power-Flo Matrix pump models: SP1591, SP1592, SP1592FT, SP1593
• Compatible with XStream Cartridge and Perflex D.E. filters: CC10093STUFFT, EC50C92SFTTL, EC50C93STL
• Works with Hayward Pro and VL series sand filter model S210T93SFT
• Replaces OEM part number SPX5500D for direct interchange

How does the included lock ring and o-ring improve performance?

The supplied lock ring secures the cover to the pump housing while the lid o-ring delivers a watertight seal that reduces air leaks and suction loss. Together they help keep debris in the strainer basket and protect the pump from cavitation caused by poor sealing.

• Lock ring secures lid quickly and resists loosening under vibration
• Rubber o-ring provides a flexible, pressure-resistant seal
• Complete kit eliminates the need to source gaskets separately
• Helps maintain designed pump prime and flow rates

What should I check before ordering this replacement cover?

Confirm your pump model and existing part number to ensure compatibility and a correct fit. Measure the lid and inspect the mounting interface for wear or damage; if the housing flange is cracked, you may need additional repairs beyond a cover replacement.

• Verify pump model matches SP1591/SP1592/SP1592FT/SP1593
• Match current part number to SPX5500D when possible
• Inspect housing flange and basket for cracks or excessive wear
• Have basic tools ready for lock-ring removal and installation

How easy is installation and what else might I need?

Installation is straightforward for anyone familiar with basic pool pump maintenance: drain the strainer pot, remove the old lock ring and lid, replace the o-ring if worn, and secure the new cover with the lock ring. No specialized tools are required, though a gentle lubricant on the o-ring can help seat the seal and extend component life.

• Simple hand tools usually suffice for removal and installation
• Replace a cracked or flattened o-ring to prevent leaks
• Application of silicone lubricant on o-ring recommended (non-petroleum)
• Turn off power and relieve system pressure before servicing

Who is this replacement cover for? Pool owners and maintenance professionals who operate Hayward Power-Flo Matrix pumps or compatible Hayward filters will find this OEM-style replacement ideal. It’s best for those who want a direct-fit repair to restore pump sealing and basket protection without replacing the entire pump, and for service technicians stocking reliable OEM components for fast field repairs.
