DESCRIPTION:

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.
