Description
xThis is a direct-fit replacement 355074 impeller designed to restore proper flow and quiet operation to Pentair SuperFlo, Sta-Rite SuperMax and Challenger 1.5 HP pool and spa pumps.
When a pump begins to make unusual noises or shows reduced water intake, the impeller is often the worn component. Replacing the impeller is a targeted, cost-effective repair that restores hydraulic performance without the expense of a full pump swap. This 355074 replacement matches the original specifications for many 1-1/2 HP Pentair and Sta-Rite models and is made with durable materials for consistent service life.
How do I know this impeller fits my pump?
Compatibility depends on your pump model and horsepower. Confirm the pump model number and that it’s a 1.5 HP Pentair SuperFlo, Sta-Rite SuperMax, Challenger or compatible Superflo VST unit before ordering.
- Fits Pentair Challenger / Pinnacle high-flow 1.5 HP inground pumps
- Compatible with Pentair SuperFlo and Sta-Rite SuperMax 1.5 HP models
- Part number: 355074 — match to your parts diagram or existing impeller
- Check the impeller lock screw location and shaft size for exact fit
What tools and steps are required to install the 355074 impeller?
Installation is straightforward for anyone comfortable with basic pump maintenance. You’ll remove the pump housing, extract the old impeller, and install the new one using the lock screw that secures it to the shaft.
- Basic hand tools: screwdrivers, pliers, and socket or wrench set
- Remove pump strainer lid and housing to access the impeller
- Unscrew the impeller lock screw, slide off old impeller, and fit the replacement
- Tighten per manufacturer torque guidance and reassemble housing
What performance improvements should I expect after replacing the impeller?
A fresh impeller typically restores pump flow, reduces vibrations and eliminates cavitation noises caused by worn vanes. You should notice improved circulation and more consistent pressure across filters and heaters.
- Improved water flow and suction compared to a worn impeller
- Quieter operation and reduced vibration under load
- More efficient filter and heater performance due to stable flow
- Extends pump life by preventing damage from imbalanced components
How durable is this replacement impeller and what maintenance helps longevity?
The impeller is built from high-performance materials to resist wear from normal pool debris and chemical exposure. Routine maintenance—cleaning the strainer basket, checking seals and avoiding dry-running—helps the impeller last longer.
- Constructed for resistance to erosion and routine wear
- Inspect and clean basket and diffuser regularly to prevent clogging
- Replace shaft seals and O-rings if they show wear to avoid leaks
- Avoid running pump dry to prevent premature impeller damage
Who is this for: pool and spa owners, service technicians and maintenance professionals who want a direct, cost-effective repair for 1-1/2 HP Pentair and Sta-Rite pumps. If you need to restore proper circulation and reduce noise without replacing the entire pump, this 355074 impeller is a practical replacement option—just confirm compatibility with your pump model and follow safe installation practices.
