Monoflo 'HydraPlus' or 'Hydra+' series is a multi-stage ring section designed for medium to high head applications. The range covers 10 sizes, up to 13 stages for most sizes. The versatile and modular design, increase the level of interchangeability of parts between the various models-sizes of pumps.

Design excellence | Optimum hydraulic design, ensuring minimum number of stages, hence reducing shaft length and distance between bearings. This results in minimum pump wear, thus extending its operating reliability and life efficiency.

Where space is a constraint, Hydra+ can be vertically mounted(Model HDV) with no compromise in its performance.
