AVF Plastic Magnetic Drive Pump
IF YOU ARE CURRENTLY USING A PUMP WITH AN INVERTER FOR VARYING DUTY POINTS, THE AVF WILL UNDOUBTEDLY REDUCE YOUR RUNNING COSTS.
A bold statement, but the new AVF canned Magnetic drive pump leads the way in high efficiency, low energy pumping. The issue is that induction motors are bulky and low in efficiency from their very design. When an Inverter is added to control the pump, the overall system efficiency is further reduced, diminishing the effectiveness of energy consumption.
Canned motor pumps integrate the design of the electric motor and magnetic drive pumps into one. The stator of the motor directly drives the inner magnet of the pump, eliminating the motor rotor and the drive magnet. Because the AVF range uses a permanent magnet rotor and there is no induced current compared to an induction motor, efficiency is increased by up to 20% and power consumption reduced by 50% or more.
When specifying any pump, the user must look at the overall life cycle cost (LCC) in order to make an informed decision. The AVF range reduces the variable costs of pump ownership (energy usage, repair costs, downtime) as these account for over 80% of the LCC.
Through in depth hydraulic, rotor, electrical and magnetic analysis, AVF motors exceed current IE3 efficiency limits. As of 2018, the 1.1kW and 2.2kW models exceed IE4 standards whereas 4kW and 7.5kW models exceed future IE5 efficiency limits.
