Description

EBARA End Suction Volute Monoblock Pump

Energy-saving design: World top class pump efficiency achieved, Major improvement over our previous models by impeller designed using our proprietary
3D inverse design technology: Higher efficiency means lower energy consumption and motor output, and more compact size.
Easy installation and simple maintenance: Alignment is not required with close coupled design, Back pull-out structure enables disassembly and inspection without removal of suction and discharge piping, Shield bearings eliminate need for adding or exchanging lubricating oil. (Up to 45kW), Shaft seal flushing piping not required for the standard application, Air-bleeding not required, Simplified shaft seal and “O” ring body seal enable easy assembly.
