OverviewThe Begemann ® BS series features a single entry, vertical in-line, close coupled single stage overhung pump. These pumps feature machined diffuser technology that optimizes hydraulic performance and radial loads. The isolated dry shaft, locked with a screw and sealed by an o-ring, enures total shaft protection from the pumped liquid. It limits shaft deflection at any flow ensuring an increased motor bearing and mechanical seal life, and longer mean time between failures.Designed with fewer rotating parts for easy maintenance, a Flexitallic compressed spiral wound gasket ensures a tight, secure metal-to-metal seal between cover and casing. A robust motor pedestal ensures low vibration levels.
