Why install an inverter to control hydraulic pumps? To have good control of all process variables and best management of measurements, increase system efficiency and reduce maintenance, as well as optimize consumption and save energy. 
 
See the details of Gefran’s proposals for the water treatment sector. 
Good management of measurement and control of process variables in water treatment systems is essential because it provides technical benefits as well as considerable returns on investment. 
 
Statistics show that industrial energy consumption by electric motors accounts for over 70% of the total worldwide; if you add the running costs of these motors, they account for over 95% of consumption. 
 
In a sector where electric motors must be used to control pumps, energy efficiency and economic sustainability must be considered for to achieve better and innovative system management. 
 

Saving Energy With Inverters 

 
 
By using inverters you can drastically lower energy consumption. This benefit is automatic only when the inverter is installed on the drive between the motor and the electrical power supply. 
 
The inverter controls all essential motor variables, such as voltage, current and nominal speed, and therefore manages torque in relation to the needs of applied loads. 
This also reduces the number of routine and extraordinary maintenance procedures, which weigh heavily on system Life Cycle Cost. 

Advanced Inverter Functions 

 
In addition to basic control functions, modern inverters have advanced functions for water treatment systems that are indispensable for process control, for system protection, for multi-pump systems, as well as energy-efficiency functions, such as: 
 
Lifting 
Level maintenance 
Distribution 
Constant pressure 
Constant flow rate 
Catchment 

Gefran’s Solutions 

Gefran proposes its latest-generation inverters, the ADV200 WA, which provides immediate and considerable savings in energy when used in a standard system with fixed-speed motor as well as due to its specific motor control functions. 
 
Even greater efficiency can be achieved by adding the AFE200 series of Active Front End regenerative power supplies, thereby creating clean power energy solutions in which THD - Total Harmonic Distortion –is less than 3% and the power factor (cosphi) approaches one. 

Applicative advantages of Gefran inverters 

 
 
 
 
What are the applicative advantages of Gefran inverters? Gefran offers specific inverters for controls in variable or square drive and with function sets for pump systems with: multi-pump control, flow rate compensation, filler function, check valve protection, pump cleaning, minimum power curve, and end curve alarm. 
 
ADV200 WAs satisfy advanced architectures in latest-generation electric motor control and management systems for the water sector. 
 
Another function lets you distribute the load in multi-pump or multi-fan systems, which reduces wear on electromechanical systems for longer system life and greater return on investment. 
 
For additional customization, the Motion Drive Programmable logic controller (MDPlc) tool lets you create advanced applications by means of a graphic interface conforming to IEC 61131-3. 
 
Lastly, the integrated control reduces system complexity and eliminates delays and noise when transmitting variables (typical on systems with separate drives and axis boards).
