The current catalog has no 60 Hz record for 250B445. Its three 45 kW 60 Hz records 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 product group on pages 29-32.
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 250B445 60 Hz record, 45 kW voltage conflict, 300B outlet conflict, certification scope and North American electrical suitability require written confirmation.
B SERIES FAQ
Selection questions answered from evidence.
How many hydraulic selections are in this B 30-45 kW 4P range?
The published data table lists 12 hydraulic selections across 150 mm, 200 mm, 250 mm and 300 mm outlets.
Does published data provide both 50 Hz and 60 Hz performance curves?
Yes. Published data presents separate 50 Hz and 60 Hz curves and identifies synchronous speeds of 1,500 rpm and 1,800 rpm respectively.
Does every model have both frequency records in the current catalog?
No. The current English catalog contains 23 records: 11 exact codes have both 50 Hz and 60 Hz entries, while 250B445 currently has only a 50 Hz entry.
Which voltage should be used for the 45 kW 60 Hz models?
Confirmation is required. Published data group specification states 380 V ±10% at 60 Hz, while the current catalog records for 150B445, 200B445 and 300B445 state 440 V.
Is the 60 Hz outlet 300 mm or 320 mm for the 300B models?
Confirmation is required. Published data table lists a 300 mm outlet, while the current 60 Hz catalog records for 300B430, 300B437 and 300B445 list 320 mm.
