Hayward SPX2700EKIT Seal Plate and Diffuser Kit for MaxFlo II Pumps
The Hayward SPX2700EKIT was the OEM seal plate and diffuser repair kit for compatible Hayward MaxFlo II pool pumps. This internal wet-end assembly supports proper impeller alignment, directs water flow through the pump housing, and provides the mounting surface for the mechanical shaft seal.
Restores Internal Water Flow
The diffuser channels water from the impeller into the pump housing, helping the pump maintain proper hydraulic performance and circulation.
Supports a Leak-Free Rebuild
The seal plate carries the mechanical shaft seal and must be in sound condition to prevent leaks between the pump housing and motor assembly.
Repair Instead of Replacing the Pump
When the housing and motor remain serviceable, replacing the damaged wet-end components can extend the life of a compatible MaxFlo II pump.
Best Repair Path for a Discontinued SPX2700EKIT
Rather than replacing the entire pump immediately, the recommended repair is to build the original kit from its individual service components. This is the most direct OEM-style repair path for a compatible MaxFlo II pump with a cracked, warped, worn, or damaged seal plate and diffuser.
- 1 x Hayward SPX2700E — seal plate.
- 1 x Hayward SPX2700B — diffuser.
- 1 x Hayward SPX2700SA — OEM shaft seal, recommended whenever the seal plate is removed.
- 1 x Hayward SX220Z2 — diffuser O-ring, recommended during reassembly.
- 1 x Hayward SPX2700ZPAK — hardware pack, only if the original hardware is damaged, corroded, or missing.
The seal plate and diffuser must match the exact pump family. Do not substitute parts from Hayward Super Pump, MaxFlo, Super II, PowerFlo, or other Hayward pump series unless the manufacturer part numbers specifically confirm compatibility.
Compatibility Guidance

- Designed for Hayward MaxFlo II SP2700X-series pool pumps.
- Commonly associated with 3/4 HP, 1 HP, 1-1/2 HP, and 2 HP MaxFlo II configurations.
- Not a universal Hayward pump repair kit.
- Confirm the complete model number before ordering individual repair components.
- Inspect the impeller, housing O-ring, motor support, shaft seal, and diffuser screws during disassembly.

When Should the Seal Plate and Diffuser Be Replaced?
A cracked seal plate, worn diffuser, damaged O-ring groove, or distorted sealing surface can create issues that look like a failed shaft seal or weak pump performance. Replacing the correct internal wet-end parts can help restore proper pump operation when the rest of the pump remains in serviceable condition.
- Water leaks appear between the motor and pump housing.
- The pump loses prime or develops air bubbles in the pump basket.
- The diffuser is cracked, worn, warped, or damaged around its screw locations.
- The shaft seal does not seat securely in the existing seal plate.
- The pump has reduced flow after ruling out clogged baskets, valves, filters, and plumbing restrictions.
- The existing wet-end parts show heat damage, chemical damage, or excessive wear.
Installation Notes
- Disconnect electrical power at the breaker before opening the pump.
- Close isolation valves and relieve pressure from the circulation system.
- Remove the motor and seal plate assembly from the pump housing.
- Inspect the impeller, shaft seal, housing O-ring, diffuser O-ring, and all screws before reassembly.
- Install the new seal plate and diffuser only after confirming the pump model and matching part numbers.
- Use a new shaft seal whenever the seal plate is removed.
- Never touch the polished ceramic or carbon faces of a mechanical seal with dirty or oily hands.
- Prime the pump fully and inspect carefully for leaks after startup.
Pump repairs involve electrical equipment, pressurized plumbing, and water. Installation should be performed only by someone qualified to safely service pool circulation equipment.
