Three Phase ESHE
End suction centrifugal pump

Performance
ESHE uses efficient two-pole motors at around 2900 rpm to deliver strong head and high flow on clean and mildly aggressive liquids. The 50 Hz range covers wide duties up to roughly 110 m head and 240 m³/h flow, so sizing is straightforward for most building services and light process applications.

Applications
Suitable for UK pressure boosting, HVAC water transfer, washdown, irrigation and OEM skids where stainless construction and a compact footprint are preferred. Use on clean water and many mildly aggressive liquids, subject to chemical compatibility.

Construction
All wetted parts are stainless steel AISI 316L, with CF8M cast stainless impellers on selected sizes. The back pull out design lets you service the rotating assembly without disturbing the pipework. The mechanical seal is EN 12756 with Ceramic and Carbon faces and FKM elastomers as standard, EPDM options available. Motors are TEFC, IP55, insulation class F. The electropump is rated IPX5.
