Mather and Platt - Single Stage Split Casing Pumps - Single Stage Split Casing Pumps ALE to EME Ranges
General Features
The ALE to EME range of pumps form a comprehensive range of heavy duty single stage horizontally split-casing pumps covering all capacities up to 2 000 l/s and heads up to 160 meters.
The range has been designed in its standard form for all general industrial applications and optional features are readily available for special applications involving corrosion, abrasion and high temperatures, which may be encountered in steelworks, chemical plants, refineries etc.
A double entry impeller is fitted to minimise axial thrust, and on large units a double volute casing is employed to limit radial forces.
The shaft assembly complete with cartridge type bearing sub-assemblies, can be removed from the pump by removing the top half casing, without disturbing main pipework connections.
The complete range has been designed to give maximum interchangeability of wearing parts between different pump sizes and is built round only 6 shaft groups each comprising shaft, sleeves and complete bearing assemblies. At the same time the impeller can be adjusted easily to give "tailor-made" performance anywhere within the range.
The pumps are suitable for direct coupled drive by electric motor, turbine or I.C. engine. Vertical operations with open or closed-type shafting can be provided.
