title: Vertical Turbine Pumps
category: Process / Pumps
description: >
When to use: Line-shaft vertical turbine pumps and submersible well pumps that lift raw water from an intake, a wet well, or a well, pump finished water from a clearwell to high service, or boost a pressurized line from a can or barrel, in water treatment plants, raw water intakes, well fields, booster stations, and industrial process plants, read with [[sync/common-work-results-process]]. Covers the four arrangements, wet-pit line-shaft turbine, can or barrel-mounted line-shaft turbine, deep-well line-shaft turbine, and submersible well pump with a submersible motor; the bowl assembly with its stages, impellers, bearings, wear rings, and strainer; the column, line shaft, shaft bearings, and the open or enclosed lubrication that decides them; the discharge head, its stuffing box or mechanical seal, and pre-lubrication; the suction can; the submersible motor, its cable, splice, and column check valve; the vertical hollow-shaft or solid-shaft motor features and the critical speed and reed frequency checks; the manufacturer's review of the intake against ANSI/HI 9.8; the factory performance, NPSH, and hydrostatic tests; field testing; the shop coating; and spare parts.

## The packing is the part that is used on a schedule, and the bearings are the parts that are used when the pump is pulled, which on a well is every few years and on an intake is whenever the strainer is found full; a plant that holds both does not wait for a shipment while the pump is on the floor. The wear rings, the seal, the splice kit, and the pre-lubrication parts are bought where the plant will do its own overhauls rather than send the pump out. {note}
