Submersible Pump Application The system consists of a submersible pump controlled by a Danfoss VLT AQUA Drive and a pressure transmitter. The transmitter gives a 4-20 mA feedback signal to the VLT AQUA Drive‚ which keeps a constant pressure by controlling the speed of the pump. To design a drive for a submersible pump application‚ there are a few important issues to take into consideration. Therefore the drive used must be chosen according to motor current. 1. The motor is a so called “Can motor”
