Introduction The vertical turbine pump (VTP) is the workhorse of municipal raw water intake, deep well extraction, and industrial cooling loops. However, it is also frequently the most misunderstood asset regarding hydraulic performance. Unlike standard horizontal end-suction pumps, VTPs often utilize mixed-flow hydraulics that create counter-intuitive power and pressure characteristics. A surprising number of premature […]

Introduction One of the most expensive misunderstandings in wastewater treatment and industrial fluid handling is the assumption that all pumps behave hydraulically like centrifugal pumps. This misconception is particularly dangerous when applied to positive displacement (PD) technology. While a centrifugal pump simply stops flowing when discharge pressure equals its shutoff head, a progressive cavity (PC) […]
