The main goal of a pumping system energy assessment is determining the current energy consumption of an existing system and identify ways to improve system efficiency.

1. Evaluation of the efficiency of a pumping system. 


- Technical condition of installed pumps. The degree of wear and tear of installed pumps,

- Operating modes.

- Control methods and algorithms.

- Evaluation of the level of maintenance and control of parameters. 


2. Developing methods of increasing pumping system efficiency.

- pump and electric motors replacement

- application of pumps control - speed control, parallel installation, a combined method of control

- upgrading of pumps (trimming of impellers, installation of new impellers

- replacing of the throttle or bypass controls

- developing control algorithms.

3. Conditions of implementation

- the acceptable cost

- the acceptable payback time
