Ring section pumps

Sulzer has a long tradition of supplying ring section mid- to high-pressure pumps to all kinds of industrial applications. The M-series is designed in a modular way based on different ranges of pressures for use in a wide range of applications, primarily for pumping clean or slightly polluted liquids.

The M-series comprises single-casing radially split multistage between bearings pumps, referred to as BB 4 type pumps in API 610. These pumps are also known as ring section pumps, segmental ring pumps, or tie rod pumps.

The modular design of the M-series pumps allows Sulzer to find the most efficient solution to meet customer requirements. Both investment cost and lifecycle costs are taken into consideration when designing the best possible pump, and the optimized hydraulic design guarantees the highest level of efficiency.
