Series Overview
Key specifications shared across the FBM series.
Water enters through the bottom and discharges at the top through the space between the motor case and water jacket. A wide gap around the semi-open impeller helps reduce clogging from mud and sand, while the hose coupling can be set vertically or obliquely to reduce hose folding.
Model Range
Compare hydraulic performance across all available power ratings.
Published data groups 480 W and 750 W pumps in one FBM section. The F suffix adds a float switch without creating a separate Contents item; FBME remains a separate intelligent series.

Published data combines each standard and float version at 11.6 kg or 13.8 kg. The current catalog gives FBM480F as 11.9 kg and FBM800F as 14.1 kg. Confirm shipment weight before quotation.
Configurations
Available 50 Hz / 60 Hz electrical configurations for each model.
Counted page codes are the base forms FBM480 and FBM800 (2 codes × both frequencies = 4 records). Single-phase models can be configured with a float switch; float codes (FBM480F, FBM800F) are not separate table rows. 50 Hz and 60 Hz stay as separate rows.

Phase / V shows catalog 220 V on 50 Hz single-phase rows and 115 V on 60 Hz single-phase rows (North American default). Published data shows 37.7 ft maximum head for FBM480(F) and 15 m / 16 m for FBM800(F) at 50 / 60 Hz. Current records publish 11.5 m at 50 Hz and 11.3 m at 60 Hz for FBM480 variants, plus 15.3 m at 50 Hz and 16.3 m at 60 Hz for FBM800 variants. Confirm the approved frequency curve before quotation.
Construction & materials
Abrasion-resistant intake around a cooled motor body.
Published data specifies a ductile-iron impeller and steel outer casing. Current catalog records describe a grey-cast-iron impeller and NBR pump housing. Confirm the supplied wet-end construction before quotation.

FBM FAQ
Configuration and source boundaries.
Why are FBM480, FBM480F, FBM800 and FBM800F on one page?
Published data defines one FBM product section with two hydraulic selections. The F suffix identifies the single-phase float-switch version, so these are configurations of one product family rather than four separate Contents items.
Why is FBME excluded from this page?
Published data Contents lists FBME as a separate intelligent drainage-pump series on pages 13-14. Although the current catalog stores FBME under the FBM series field, its records are deliberately excluded here.
How many current FBM configurations are published?
After excluding FBME, counted page codes are the base forms FBM480 and FBM800 (2 codes × both frequencies = 4 records). Single-phase models can be configured with a float switch; trailing-F codes are not separate counted rows.
What voltage is shown for 60 Hz rows?
The configuration table keeps 50 Hz single-phase at the catalog 220 V value and displays 115 V for 60 Hz single-phase rows as the North American default. The supply ribbon matches that 115 V NA default.
Can FBM operate at a low water level?
Published data routes discharge water through the space between the motor case and water jacket. This cooling arrangement supports continuous operation at low water level within the published operating limits.
Why are head, material and weight differences disclosed?
Some current catalog values differ from published data, including maximum head, float-version weight and impeller description. Confirm the approved curve, supplied construction and shipment weight before quotation.
