Select the 50 Hz configuration by its duty point
This reference uses the exact FSM21.5 50 Hz, single-phase 220 V row. The manufacturer publishes a rated 66.0 US gpm at 52.5 ft, and lists maximum flow and head as separate endpoints. The maximum figures should not be combined into one operating condition.
Calculate total head from lift, hose length, fittings and discharge conditions, then request the approved curve for that operating point. The 60 Hz / 115 V row has different performance and electrical requirements, so it is not interchangeable with this reference.

Check the liquid and installation conditions
MEUDY describes a semi-vortex impeller and a shaft-mounted agitator for muddy drainage. The published 6 mm passage and series liquid limits define useful selection boundaries, rather than approval for every slurry or chemically aggressive liquid.
Give the solids size and concentration, likely abrasive content, temperature and pH. Confirm cable protection, pump support, immersion level and the required starting or level-control arrangement for the actual pit.
Use the model drawing to plan discharge and access
The manufacturer links this outline drawing directly from the 50 Hz FSM21.5 row. It shows the 50 mm outlet and the pump envelope; use a current approved drawing to settle the hose connection, lifting access and installed clearance.
The product image is shared with another power variant, and the F-suffix versions have separate model references. Specify the exact model code, electrical supply, required controls and spare seal or wear-part package rather than selecting by appearance alone.

Planning your configuration
- State flow, total head, supply frequency/voltage, liquid conditions and hose arrangement. Request the approved 50 Hz performance curve.
- Maximum flow and head are separate endpoints. Float controls, certification, local stock and service scope need confirmation for the selected build; manufacturer illustrations are not GLOBSEEK inspection evidence.
