ESC
series are Horizontal Split casing
Double suction impeller with in-between
bearing design, allows pumps run quietly and with minimal
vibration. Coupled with dynamically balanced impeller the
pumps life is greatly prolonged and therefore, increase
MTBF (Mean Time Between Failure). This allows the pump to
be mounted horizontally and also, vertically to save spaces.
Shaft is fully sealed away from medium, no erosion and
also high interchangeability.
Closed circulate cooling system is applied to its inner seal
housing. Because of that, pump structure is simple and also
easy to maintain.
Application:
HVAC and Cooling Tower
Municipal Water Supply
Marine and Ship Building
Power Plant
Irrigation and agriculture
Fire Fighting
