The proven SignaSeal staging system utilizes a patented ceramic wear surface. When incorporated with Sta-Rites true independent floating impellers, dominates with 1st-in-class performance, superior sand handling, and a thrust management staging system with industry exclusive dry-run capabilities..
The ST.E.P. Plus Dominates in this class with the lowest draw-down of 4-1/2 in (a standard 4 in NEMA submersible only draws-down to 13-1/2 in)..
The ST.E.P. Plus Dominates in this class with less energy consumption over 25% less amp draw (9.5 amps vs. 12.7 amps, 115 volt) than a 4 in NEMA submersible, reducing operating costs and extending the service life of float switch contacts..
The ST.E.P. Plus Dominates by using the pumped liquid to cool the motor as it passes over the motor. The water passing over the motor dampens the motor noise, eliminating expensive flow-inducer sleeves required when using a standard 4 in NEMA submersible..
