The ST.E.P. Plus D Series 4” submersible pump in 10, 20 and 30 GPM models dominate with superior “draw-down” capability, with reduced amp draw and with cooler and quieter operation.
- The proven SignaSeal staging system utilizes a patented ceramic wear surface. When incorporated with Sta-Rite’s “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” (a standard 4” NEMA submersible only draws-down to 13-1/2”).
- 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” 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” NEMA submersible.
