Pentair EQ Series Impeller for EQW300 and EQ1500 Commercial Pumps (350027Z)
Closed impeller for EQ Series commercial pumps.
The Pentair 350027Z is the impeller (key no. 15) for EQ Series high performance commercial pumps, listed for the 3 HP EQ300 / EQW300 and EQK300 and the 15 HP EQK1500 models, among others. On every model that uses it, Pentair pairs it with diffuser 356735Z. Pentair credits the EQ Series' efficiency to its closed impeller design, which it says lets the motor run cooler.
Why PST Customers Pick This
Closed Impeller Design
Pentair lists a closed impeller for longer motor life and an efficient impeller design for lower motor load among the EQ Series' features.
Listed by Model
Pentair's EQ Series parts table names 350027Z for the EQ300 and EQK300, the EQK1500, EQK1500 575V and EQKT1500, and the explosion-proof and 50 Hz EQK1000.
Keyed to the Shaft
The impeller is keyed to the motor shaft with a parallel key and held by a socket head screw and washers. Align the keyway with the key, push it fully on, and tighten the screw securely.
Check It Spins Free
After fitting the diffuser around the impeller nose, rotate the impeller by hand to confirm it turns freely. Pentair warns a bound impeller can stop the motor from starting or make it draw excessive amps.
Inspect the Vanes
Pentair calls it good practice to check that the vane passageways are open and no vanes are broken or worn. A clogged impeller is one cause of low flow with low filter pressure.
Service Notice
Pentair states this pump should be installed and serviced only by a qualified pool service professional. Always disconnect power at the circuit breaker before servicing, and lock out or tag the circuit so it cannot be switched on while you work.
