Detailed Overview
Dual Voltage Flexibility: The pump’s ability to operate on either 230V or 460V provides installation flexibility across various commercial sites. At 230V, it draws 13.2 amps, while at 460V, the current draw halves to 6.6 amps—delivering roughly the same power output. This not only helps optimize wiring and installation costs but also minimizes voltage drop concerns over long cable runs.
Robust Commercial Design: Designed specifically for commercial and public swimming pools, spas, water parks, and aquatic facilities, the Sta‑Rite D‑Series pump balances solid performance with reliable, continuous operation. Its self‑priming capability ensures that it quickly regains prime even after a temporary loss in suction, a crucial feature for maintaining the high flow regimes demanded in busy pool facilities.
Efficient Yet Rugged: While this is classified as a standard efficiency pump (and may not be as energy optimized as premium efficiency models), it makes up for it with durability and ease of maintenance. Its construction using cast iron and bronze means that the pump is built to withstand the rigors of a high-use commercial environment.
Performance Characteristics: Operating at 3450 RPM, the pump delivers a strong hydraulic performance with a medium head profile that supports high flow rates and significant lift pressures—ideal for long pool circulation loops or multi-zone commercial installations.
Applications & Considerations
-
Commercial & Public Pools: Its self-priming feature and robust motor design make it an excellent choice for locations where uptime and reliability are crucial.
-
Aquatic Facilities & Water Parks: Designed to handle continuous operation, this pump ensures the efficient circulation and filtration required in high-usage environments.
-
Installation Flexibility: With dual voltage capability, facility managers can choose between a 230V or 460V supply depending on the available infrastructure. Lower current draw at 460V offers benefits like smaller conductor sizes and reduced energy losses over long distances.
-
Maintenance and Service: Easy access for routine maintenance is facilitated by features like back pull-out designs (typical of many Sta‑Rite models) that allow the complete removal of the motor without disturbing plumbing connections. This means less downtime and a straightforward service process.
