Series Overview
Key specifications shared across the 80U...K-80 series.
This 80 mm U-K block covers residential, agricultural, industrial, flood-control and sanitary-sewer duties. Published data specifies cast-iron four-pole vortex hydraulics, water up to 40°C, pH 6-10, an 80 mm radial flange outlet and an 80 mm solids passage. 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.
Each frequency cell shows published rated flow/head and maximum flow/head in GPM/ft. S and SF configurations use the 2.01 HP hydraulic row.

Available 50 Hz / 60 Hz electrical configurations for each model.
Counted page codes are the K and SK forms (6 codes, 11 frequency records). Where an SK code has no matching 60 Hz catalog row, 60 Hz is customizable for that code. Single-phase models can be configured with a float switch; float codes (80U41.5SFK-80) are not separate table rows.

SOURCE & REVIEW
The named table block defines this page.
50 Hz published
Shared introduction and construction; page 4 selection block, page 9 detailed curve/data, and pages 14-16 installation dimensions.
60 Hz published
The same five hydraulic rows with separate 60 Hz maximum performance and electrical tables.
Current catalog
Eleven K/SK records (SF float option 80U41.5SFK-80 kept outside the count), five content-distinct product images and six content-distinct dimension drawings. Frequency gaps and 50 Hz curve conflicts remain subject to confirmation.
80U...K-80 4P FAQ
Configuration questions answered from evidence.
Why are the 80U...K-80 4P models on one page?
The 50 Hz and 60 Hz published books each define one named 80U...K-80 4P performance block with five hydraulic rows. Frequency and the S/SF electrical choices remain configurations inside that group.
Which 80U...K-80 4P models have single-phase or float variants?
Only the 2.01 HP hydraulic selection has current S and SF codes: 80U41.5SK-80 is single phase and 80U41.5SFK-80 is single phase with a float switch. Both appear only as 50 Hz records in the current English catalog.
Why are there six 50 Hz records but only five 60 Hz records?
The five base K codes each have both frequencies, and 80U41.5SK-80 adds one 50 Hz record (six 50 Hz / five 60 Hz). The SF float code 80U41.5SFK-80 is kept outside the page count.
Why do some 50 Hz catalog maximum heads conflict with published data?
The 50 Hz published lists maximum heads of 26.2, 32.8, 42.7, 49.2 and 59.1 ft across the five rows. Current base catalog records list 32.5, 40.4, 53.5, 63 and 58.4 ft. Confirm the approved curve before quotation.
How do 50 Hz and 60 Hz hydraulics differ?
Rated points are the same in published data, while several maximum heads differ. For example, 80U47.5K-80 has a 506/59.1 maximum at 50 Hz and 506/65.6 at 60 Hz, in GPM/ft.
What cable length applies to this group?
Published data and current catalog use 8 m cable for the 2.01 HP and 2.95 HP selections, and 10 m for 4.96-10.1 HP selections.
