Description
Sta-Rite seal plate with mechanical seal for Superflo, Supermax and S5P1R R355612SS
The Sta-Rite seal plate with mechanical seal for Superflo, Supermax and S5P1R R355612SS is a complete rear housing and shaft seal assembly for
Sta-Rite SuperFlo, SuperMax and S5P1R pool pumps. By replacing the original seal plate and mechanical seal in one operation, this kit restores a
dry, secure interface between the motor and the wet end and helps stop leaks around the pump shaft.
Main features of the R355612SS seal plate kit
- Original style Sta-Rite seal plate with pre installed mechanical shaft seal.
- Compatible with SuperFlo, SuperMax and S5P1R pump housings.
- Creates a watertight barrier between the hydraulic body and motor flange.
- Designed for continuous duty in chlorinated and salt treated pool water.
Function in Sta-Rite Superflo and Supermax pumps
In Sta-Rite SuperFlo, SuperMax and S5P1R pumps, the seal plate forms the rear wall of the volute and supports the mechanical seal around the motor
shaft. It keeps pool water under pressure inside the pump body while preventing it from reaching the motor bearings. A sound R355612SS assembly is
essential to avoid leaks, rust on the motor and premature bearing failure.
- Holds and centres the motor shaft in relation to the impeller and diffuser.
- Positions the rotating and stationary faces of the mechanical seal correctly.
- Ensures the pump operates leak free at normal filtration pressures.
Compatibility and identification
This seal plate and mechanical seal assembly is used on a family of Sta-Rite pumps that share the same wet end design. It is the correct replacement
part when the exploded diagram or spare parts list specifies reference R355612SS as the seal plate for your model.
- Sta-Rite SuperFlo circulation pumps that list R355612SS in the parts breakdown.
- Sta-Rite SuperMax pumps with the same rear housing and shaft seal layout.
- Sta-Rite S5P1R models using the SuperMax style wet end and seal plate.
Always confirm the pump model on the data plate and cross check with the manufacturer spare parts diagram before ordering, to make sure this kit matches
your exact SuperFlo, SuperMax or S5P1R version.
When to replace the seal plate and mechanical seal
Seal plates and mechanical seals are exposed to heat, pressure and pool chemicals. Over time they can wear, crack or deform, allowing water to pass
between the wet end and the motor.
- Visible water drips or salt deposits at the junction between motor and pump housing.
- Rust marks or moisture on the motor foot or under the pump.
- Cracks or erosion visible on the existing seal plate.
- Motor bearing noise that may indicate past water ingress through a failed seal.
Replacing the complete assembly with a new Sta-Rite seal plate with mechanical seal for Superflo, Supermax and S5P1R R355612SS is often more reliable
than changing only the seal in an old, damaged plate.
Installation guidelines
Installing this kit involves separating the wet end from the motor and handling the shaft and impeller. The work should always be done with the power
isolated and the hydraulic circuit depressurised.
- Disconnect the pump from the electrical supply and make sure it cannot start accidentally.
- Close the valves and open unions or drain plugs to empty the pump housing.
- Remove the bolts that join the wet end to the motor and pull the two sections apart.
- Hold the motor shaft as specified by the manufacturer and unscrew the impeller carefully.
- Remove the old seal plate and mechanical seal and clean the motor flange and shaft shoulder.
- Fit the new R355612SS seal plate, making sure the pre installed mechanical seal remains clean and correctly seated.
- Reinstall the impeller, refit the housing and tighten the bolts evenly around the pump.
After reassembly, open the valves, prime the pump if necessary and run it while inspecting the joint between the wet end and motor for any sign of
leakage.
Good practice for longer service life
Correct operating conditions help the new seal plate and mechanical seal last longer and protect the motor.
- Do not run the pump dry; always ensure the housing is fully primed before starting.
- Maintain balanced water to limit corrosion and scale around metallic parts.
- Check the pump regularly for moisture around the base and correct small leaks quickly.
- Keep pipework well supported so vibration and mechanical stress on the pump body are minimised.
With a correctly installed Sta-Rite seal plate with mechanical seal for Superflo, Supermax and S5P1R R355612SS, the pump wet end is once again properly
sealed and ready for many more seasons of reliable filtration.
