VERTICAL TURBINE PUMP REPLACEMENT BRIEF
Edition: October 3, 2026
Guide: https://yenra.com/turbine-pumps/

Purpose: collect the information a qualified supplier or engineer needs to
review a replacement. This is a record, not a sizing or installation procedure.
Use existing records and measurements obtained under approved procedures.
Do not enter a wet well, remove guards or open electrical equipment to fill it.
Write UNKNOWN where evidence is missing. Attach supporting drawings and data.

Resolution / supporting document / reviewer:

ILLUSTRATIVE HEAD EXAMPLE -- NOT A DESIGN
Two open tanks: elevation difference 18 m; losses at target flow 7 m.
Ignoring velocity differences: required head = 18 + 7 = 25 m.
If source level falls 3 m, head becomes 28 m at the same flow/assumed losses.
Real selection also requires the complete curve, operating range, inlet
conditions, liquid properties, mechanical fit and qualified review.
