DESMI ESLHT horizontal end suction centrifugal pump designed for high media temperatures for boiler water application and district heating applications up to 180°C.
Concept Features:
• Duplex stainless steel shaft.
• Closed impeller design to achieve high efficiency even in small capacity pumps.
• Carbon sleeve bearing as main bearing to obtain optimal performance in self-lubrication and heat resistance.
• Balanced mechanical shaft seal to increase sealing reliability by its less seal face wear / heat development.
• Separate shaft seal chamber with cooling fins located away from main pump casing to protect shaft seals from heat transfer.
• Back pull design without disturbing pump casings and external pipes during maintenance.
• Automatic air vent valve on top of shaft seal chamber to prevent dry run and/or overheating seal.
• Air fan on flexible coupling for cooling of bearing and shaft seal arrangement.
Application areas:
• High temperature water circulation.
• District heating purposes.
