Vertical multistage inline pump for high-flow applications
The new CR 185 vertical multistage inline pump (photo) is the latest addition to this company’s CR range. Through advanced simulation-driven design, the CR 185 now delivers the most performance in its class — up to 1,275 gal/min and 1,230 ft of head. The CR 185 is suitable for high-flow water supply, water-transfer and water-treatment applications where energy efficiency is paramount. An improved impeller design reduces energy loss and the optimized flow path reduces pressure loss, both of which improve the pump’s efficiency. On pumps up to 30 hp, the CR range features an integrated variable frequency drive (VFD), the MLE motor, and for pumps larger than 30 hp, a panel-mounted CUE VFD is available to offer further energy optimization, efficiency and control. Low vibration reduces noise and ensures a longer lifespan. Additionally, balanced radial loads prevent shaft deflection that is common in single-stage pumps. A new thrust-handling device allows the use of standard motors on pumps with 100-hp motors and above. — Grundfos Pumps Corp., Brookshire, Tex.
