Series Overview
Key specifications shared across the U 0.45-1.5 kW series.
Published data specifies IP68 protection, class F insulation, water temperature up to 40°C and pH 6-10. The 50 Hz and 60 Hz curves are shown separately at synchronous speeds of 3,000 rpm and 3,600 rpm. North American pages show motor power in HP, flow in GPM and head in ft.
Model Range
Compare hydraulic performance across all available power ratings.
Eight performance rows, kept together on one page. Rated and maximum columns show flow / head in GPM / ft. Outlet is 50 mm and impeller passage is 35 mm across all eight rows.

Counted page codes are the base and S forms (8 codes, 15 frequency records). Only three-phase 50U2.45 lacks a 60 Hz record among counted codes. Matching SF float-switch codes (50U2.45SF, 50U2.75SF, 50U21.1SF, 50U21.5SF) use the same hydraulics and are not added to this count.

The table preserves current catalog values rather than replacing them with rounded published limits. A 60 Hz record for three-phase 50U2.45 is not present and should not be inferred from the single-phase record.

SOURCE & REVIEW
Evidence stays tied to this U entry.
Published source
MEUDY sewage pump catalog 2026.6.6, printed pages 38-39 with specifications, materials, curves, performance rows, dimensions and the SF suffix note.
Current catalog
Exact phase, frequency, voltage, float-switch, product-image and dimension assignments come from the current English U records.
Confirmation
The missing 50U2.45 60 Hz record, certification scope and North American electrical suitability require written confirmation.
U SERIES FAQ
Selection questions answered from evidence.
How is the U 0.45-1.5 kW 2P range grouped?
The published data treats it as one product entry with eight hydraulic performance rows. Counted page codes are the base and S forms (8 codes, 15 frequency records). Matching SF float-switch codes remain outside that count.
What does SF mean in this U range?
the published footnote states that U...SF identifies a single-phase pump with a float switch. S identifies the corresponding single-phase pump without the float switch.
Does every counted code have both 50 Hz and 60 Hz catalog records?
No. The counted English catalog set has 15 records. Every counted code except the three-phase 50U2.45 has both frequencies; 50U2.45 currently has only a 50 Hz record. SF float codes are kept outside this count.
What supply voltage does this range use?
Published data specifies 380 V +/-10% for three-phase supply and 220 V +/-10% for single-phase supply at both 50 Hz and 60 Hz.
Can the maximum flow and head be used as a guaranteed duty point?
No. The 123.3 GPM maximum flow and 59.1 ft maximum head describe published data range envelope and do not occur at the same operating point. Confirm the required duty against the appropriate curve.
