The current catalog has no 60 Hz record for 200B490. Its 60 Hz records for 200B475, 250B475, 300B475, 400B645 and 400B655 list 440 V instead of published data's 380 V +/-10%, and the three 300B 60 Hz records list 320 mm outlets instead of 300 mm. Do not substitute or reconcile these values without written confirmation.

SOURCE & REVIEW
Evidence stays tied to this group.
Published source
MEUDY sewage pump catalog 2026.6.6, shared B applications on page 4 and this mixed-pole product group on pages 30-33.
Current catalog
Exact frequency, voltage, outlet, image and dimension assignments come from current English catalog records; conflicting values are retained rather than normalized.
Confirmation
The missing 200B490 60 Hz record, five voltage conflicts, three outlet conflicts, certification scope and North American electrical suitability require written confirmation.
B SERIES FAQ
Selection questions answered from evidence.
Why are the four-pole and six-pole models on one page?
The published data defines B 55-90 kW 4P and B 45-55 kW 6P as one product entry across pages 30-33, with one shared specification and model table.
How many hydraulic selections are in this B range?
Published data table lists 11 hydraulic selections: nine four-pole models and two six-pole models across 200 mm, 250 mm, 300 mm and 400 mm outlets.
Does every model have both frequency records in the current catalog?
No. The current English catalog contains 21 records. Ten codes have both 50 Hz and 60 Hz entries, while 200B490 currently has only a 50 Hz entry.
Which voltage should be used for the listed 60 Hz models?
Confirmation is required. Published data group specification states 380 V +/-10% at 60 Hz, while five current catalog records state 440 V.
Is the 60 Hz outlet 300 mm or 320 mm for the 300B models?
Confirmation is required. Published data table lists 300 mm, while the current 60 Hz catalog records for 300B455, 300B475 and 300B490 list 320 mm.
