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
