PENTAIR SBI vertical multistage pump range

Wednesday, 30 March, 2016 | Supplied by: Pentair

PENTAIR SOUTHERN CROSS has partnered its SBI vertical multistage pump range with electric motor and drive manufacturer WEG. All SBI units are built with WEG W21 motors, while the variable speed units harness drives also produced by WEG.

The SBI range is available in a wide range of sizes producing volumes from 1–150 m3/h and heads in excess of 300 m. The vertical multistage offering is available in a number of configurations, including single-pump and multipump pressure systems. The pumps and pressure systems are suitable for applications including pressure boosting; process water in industrial and commercial situations; seawater pumping; and irrigation. The pressure systems are available in fixed-speed and variable-speed operation.

The pump range provides an efficient, high-performance way to provide large volumes of water at high heads while maintaining a compact, space-saving design. All wetted components are constructed from 304 grade stainless steel (316 grade available). The pressure systems are built on galvanised steel bases and are supplied assembled with the necessary manifolds, valves, pressure vessels and pressure switches/transducers, allowing for fast and easy installation.

The variable speed pump sets are fitted with WEG’s CFW08 or CFW11 (dependent on motor size) variable speed drive (VSD). The WEG PLC300 controls the multipump sets and can manage up to eight pumps in unison. Each pump has its own VSD, allowing for individual operation should the controller unexpectedly fail. Other failsafe measures of the drives include resorting to a fixed-speed operation should the transducer fail and a ‘pipe fill mode’ function that prevents the system going out on a failure when commissioning.
