March May TE

March May TE is a widely used sealless magnetic-drive centrifugal pump range for transferring and circulating aggressive or process-sensitive liquids. Typical duties include chemical transfer, chemical recirculation, fume scrubbers, electroplating and surface treatment, refrigeration systems, marine air conditioning, laboratory equipment and water treatment. The broad material and size choice allows the range to cover many compact process duties where secure containment and straightforward maintenance are priorities.

The TE uses a single-stage centrifugal hydraulic design with a magnetic coupling between the motor and impeller. Because torque is transmitted through the containment shell, the design avoids a dynamic mechanical shaft seal and therefore removes a common leakage and wear point. Depending on model, TE pumps are available in polypropylene, Ryton, PVDF or stainless steel, with threaded or flanged connection options to suit the installation.

The current TE range is published for flows up to 39.2 m³/h, heads up to 34.1 m, system pressure up to 13.7 bar and temperatures up to 121 °C. These are range-level maxima and are not available simultaneously on every model or material configuration, so the required operating point and chemical compatibility must be checked against the selected pump. Selection should also consider specific gravity, viscosity, solids content, NPSH, motor specification and any hazardous-area requirements.

For plant owners, the TE range combines broad chemical compatibility with a sealless architecture that can reduce routine shaft-seal maintenance and help contain aggressive liquids. The right material and hydraulic size are critical to reliability, particularly when temperature, concentration or specific gravity changes across the process. AxFlow can support TE model selection, materials review, spare parts and replacement planning to help maintain process continuity and control lifecycle cost.
