CEC-NMD - Water Pumps

CEC-NMD WATER PUMP SINGLE IMPELLER

The compact design allows for easy installation even in confined spaces. The mechanical structure of the hydraulic parts in contact with the pumped liquid is dimensioned to guarantee the maximum resistance to mechanical stress.
The lantern bracket design prevents contact with the pump's rotating parts, protecting the end user whilst allowing for inspection of the mechanical seal.
The bearing and shaft are designed to ensure the reduction of stress, providing high reliability under all operating conditions.

CEC-NMD WATER PUMP TWO BACK-TO-BACK IMPELLER

The option to choose between cast iron and bronze materials for the hydraulic parts in contact with the pumped liquid allows two back-to-back impeller series pumps to be selected for use with different types of liquids.
The mechanical structure of the hydraulic parts in contact with the pumped liquid is dimensioned to guarantee the maximum resistance to mechanical stress.
The bearing and shaft are designed to ensure the reduction of stress, providing high reliability under all operating conditions.

CEC-NMD WATER PUMP APPLICATIONS

For clean liquids without abrasives, which are, non aggressive for the pump materials ( solids content up to 0.2%).
For water supply.
For heating, air-conditioning, cooling and circulation plants.
For civil and industrial applications.
For irrigation.
