INTRODUCTION

Mechanically powered turbine pumps were first developed and manufactured in 1904 by the Layne & Bowler Pump Company. Because of this established industry leadership billions of gallons more will be pumped by Layne & Bowler pumps in the future. The vertical turbine pump has, from its inception, been specified for difficult or unusual applications. Among these are limited floor space, reduced operating noise levels, high efficiency, high discharge pressures and unusual suction conditions- such as required for low NPSH. All vertical turbines look quite similar. In fact, most manufacturers have designed their pumps, when practical, to allow installation within a range of standard well casing pipe sizes. Beyond external appearances, the pumps reflect a more unique character when considering applications. some are designed only for wells, some for short settings, others for low pressure, some for high pressure, etc. The vertical turbine is one of three basic pump designs which also includes mixed flow and propeller types. Standard Francis Vane impeller type turbine pumps described in this bulletin produce low to medium volumes of water at high pressure. Layne & Bowler vertical pumps are designed primarily for heavy duty, continuous operation, municipal and industrial applications. As a result, Layne & Bowler vertical pumps are unique when compared to the rest of the pump industry for normal, less demanding applications. The average installation can expect extra-long trouble-free pump life. This bulletin on short set pumps explains how one variation of the basic vertical design can best suit your specific application. A review of this bulletin will show you why Layne & Bowler offers the most value in vertical turbine pumps. A local sales office is listed in the yellow pages.
