ECN-17

Function of ECN-17 in circulation systems

The main function of ECN-17 is to create liquid flow and pressure differential in closed or semi-closed circulation systems. The pump provides transfer and circulation of water or coolant through equipment that requires thermal stabilization. In the supplied context, its main application is in cooling systems of special ground-based equipment and radio-electronic equipment. Depending on modification and documentation, related versions may also be used with diesel fuel or liquid chemical agents.

Drive motor and operating principle

ECN-17 is driven by the MT-3000-2S electric motor. The motor converts electrical energy into mechanical rotation, which drives the centrifugal pump impeller. During operation, the rotating impeller accelerates the working liquid and creates flow through the pump body. This centrifugal principle allows the pump to maintain circulation at the required flow rate and pressure differential. Correct operation depends on the motor condition, liquid compatibility, electrical supply and installation according to the technical documentation.

Working liquids and modifications

The base ECN-17 version is intended for distilled water, drinking water and coolant grade “65” according to the supplied technical description. The source context also mentions ECN-17(Skh)M as a specialized modification adapted for liquid chemicals and fuel in agricultural or special equipment applications. Because working-liquid compatibility may differ by modification, the exact version, seal materials and intended medium should be confirmed before installation or procurement.

Technical performance of ECN-17

According to the supplied data, ECN-17 operates from a 200 V, 400 Hz supply through the MT-3000-2S drive motor. The pump delivery is specified as 3000 or 9000 l/h depending on mode or modification. The pressure differential is not less than 392.4 kPa, corresponding to 4 kgf/cm². The pump current consumption is not more than 16 A, and the mass of the pump assembly is not more than 14 kg. These parameters should be checked against the passport of the exact supplied unit.

Identification and ordering of ECN-17

Before ordering ECN-17, the buyer should confirm the exact modification, working liquid, required flow rate, installation conditions, motor version and documentation set. It is also important to clarify whether the pump is required as a complete assembly with MT-3000-2S or as a pump unit for repair / replacement. The item may be required for cooling-system maintenance, liquid circulation repair, special equipment support or spare parts stock. Product passport, test records and preservation documents should be checked before shipment.
