Series Overview
Key specifications shared across the B 0.75-1.5 kW series.
The B series uses a channel impeller with a wide channel intended to reduce clogging in sewage and wastewater duties. Current catalog records include three-phase and single-phase configurations. Published data defines S as single phase with float switch; the separate SF catalog suffix requires confirmation before quotation. North American pages show motor power in HP, flow in GPM and head in ft.

S is defined in published data as single phase with float switch and remains in the page count. Matching SF float-switch codes (50B2.75SF, 50B21.1SF, 50B21.5SF, 65B21.1SF, 65B21.5SF) are kept outside this count; Published data does not define SF, so confirm its supply scope. Voltage, availability and full curve suitability also require quotation review.

B SERIES FAQ
Questions to settle before selection.
How many hydraulic selections are in this B pump range?
The published data table lists five hydraulic selections across 50 mm and 65 mm outlets. Counted page codes are the base and S forms (10 codes, 19 frequency records). Matching SF float-switch codes remain outside that count.
Does this range include both 50 Hz and 60 Hz data?
Yes. Published data shows both curve sets, and this page keeps the separate catalog records visible. Confirm the complete curve for the required frequency.
What do the S and SF suffixes mean?
Published data defines S as single phase with float switch and those S codes remain in the page count. Separate SF catalog codes are kept outside the counted models and configuration table; Published data does not define SF, so its supply scope requires confirmation.
Are certifications confirmed for every code on this page?
No model-specific certification is claimed here. Certification scope and North American electrical suitability require written confirmation for the quoted configuration.
