Series Overview
Key specifications shared across the 65U...K-50 series.
This 65 mm U-K block covers residential, agricultural, industrial, flood-control and sanitary-sewer duties. Published data specifies cast-iron vortex hydraulics, water up to 40°C, pH 6-10, a 65 mm radial flange outlet and a 50 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.

SOURCE & REVIEW
The named table block defines this page.
50 Hz published
Shared introduction and construction; page 3 selection block, page 6 detailed curve/data, and pages 14-16 installation dimensions.
60 Hz published
The same six hydraulic rows with separate 60 Hz rated points, curve endpoints and electrical tables.
Current catalog
Fourteen K/SK records (SF float option 65U21.5SFK-50 kept outside the count), five content-distinct product images and seven content-distinct dimension drawings. Power conflicts and certification scope remain subject to confirmation.
65U...K-50 2P FAQ
Configuration questions answered from evidence.
Why are the 65U...K-50 2P models on one page?
The 50 Hz and 60 Hz published books each define one named 65U...K-50 2P performance block with six hydraulic rows. Frequency and the S/SF electrical choices remain configurations inside that group.
Which 65U...K-50 models have single-phase or float variants?
Only the 2.01 HP hydraulic selection has a single-phase SK code (65U21.5SK-50) in the counted model list. Matching SF float code 65U21.5SFK-50 uses the same hydraulics and is kept outside the page count. The other counted codes are three phase.
Why do two current catalog powers differ from published data?
Published data identifies 65U21.5K-50 as 2.01 HP and 65U22.2K-50 as 2.95 HP. Their current 50 Hz catalog records list 2.28 HP and 3.22 HP respectively, while the 60 Hz records retain 2.01 HP and 2.95 HP. Written confirmation is required.
How do 50 Hz and 60 Hz hydraulics differ?
Every hydraulic row has separate published values. For example, 65U211K-50 is rated 159/108 with a 317/131 maximum at 50 Hz, versus 159/115 rated and 317/144 maximum 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 4.96-14.8 HP selections.
