Configurations

Available 50 Hz / 60 Hz electrical configurations for each model.

Counted page codes are the base and single-phase S forms (14 codes, 14 frequency records). Single-phase models can be configured with a float switch; ALSF/ASF codes are not separate table rows. 60 Hz is available as a customization.

Published data specification mentions 50 Hz and 60 Hz supply and synchronous speeds, but its curves and performance table are 50 Hz. The current English UA catalog also contains only 50 Hz records, so 60 Hz duties remain unverified.

SOURCE & REVIEW

Evidence stays tied to Type A.

01

Published source

MEUDY sewage pump catalog 2026.6.6, printed pages 40-43 with specifications, materials, curves, performance rows and R, Y and Z installation drawings.

02

Current catalog

Exact model, phase, frequency, voltage, image and dimension assignments come from the current English UA records; UA-SS is excluded.

03

Confirmation

Any 60 Hz performance, certification scope and North American electrical suitability require written confirmation.

U TYPE A FAQ

Selection questions answered from evidence.

How is the U 0.45-5.5 kW 2P Type A range grouped?

The published data treats it as one product entry with 14 hydraulic performance rows. Counted page codes are the base and single-phase S forms (14 codes, 14 frequency records). Matching ALSF/ASF float-switch codes remain outside that count.

What installation arrangements does Type A support?

Published data documents movable soft-pipe installation R, hard-pipe installation Y and auto-coupled installation Z, with separate dimension drawings and tables.

Which Type A codes have float switches?

Published data identifies the ALSF suffix as single phase with a float switch. The current catalog contains four ALSF codes plus 65U21.5ASF, all as single-phase configurations.

Are 60 Hz Type A configurations published in the current catalog?

60 Hz is customizable. Published data mentions 50 Hz and 60 Hz supply; the counted English UA catalog set currently publishes 14 records at 50 Hz. Float-switch ALSF/ASF codes remain outside this count.

Can 326 GPM and 27 m be treated as one duty point?

No. They are separate maximum-flow and maximum-head limits for the range. Confirm the required operating point against the relevant pump curve.

Confirm the duty point, installation, phase and float-switch requirement.
