Series Overview
Key specifications shared across the FDM series.
Published data pairs an effective motor with high-chrome-alloy impeller and agitator components for highly laden mud water. Its semi-vortex hydraulic arrangement reduces clogging associated with excessive sand.
Model Range
Compare hydraulic performance across all available power ratings.
Published data keeps FD, FDM and the float-switch suffix inside one FDM performance block. FDME is a separate Contents item and is excluded even though the catalog shares its series field.

Published data combines FDM2.55 and FDM2.55F at 15.5 kg; the current catalog gives non-float FDM2.55 as 15.2 kg and float FDM2.55F as 15.5 kg. Confirm shipment weight before quotation.
Configurations
Available 50 Hz / 60 Hz electrical configurations for each model.
Counted page codes are the FD/FDM base forms (2 codes × both frequencies = 4 records). Single-phase models can be configured with a float switch; float codes (FDM2.55F) are not separate table rows. The table preserves phase, voltage, duty points, maximum points, outlet, passage, weight, cable length and every model-specific drawing link in server-rendered HTML.

FDM FAQ
Configuration and source boundaries.
Why are FD and FDM configurations on one page?
Published data defines one FDM performance block. FD identifies three phase, FDM single phase, and the F suffix a single-phase float-switch configuration.
Why is FDME excluded from this page?
Published data Contents lists FDME as a separate intelligent slurry-pump series on pages 09-10. Although the current catalog stores FDME under the FDM series field, its records are deliberately excluded here.
How many current FDM configurations are published?
After excluding FDME, counted page codes are the base forms FD2.55 and FDM2.55 (2 codes, 4 frequency records). Matching F float-switch code FDM2.55F remains outside that count.
Which components handle abrasive slurry?
Published data specifies a high-chrome-alloy impeller and agitator, plus a steel strainer. The semi-vortex arrangement reduces clogging caused by excessive sand.
Why are material and weight differences disclosed?
Published data lists a cast-iron pump body and 15.5 kg for FDM2.55(F). The current catalog describes the pump housing as a steel-and-rubber combination and gives 15.2 kg for non-float FDM2.55. Confirm the supplied construction and weight before quotation.
