KSB: Motor-mounted speed control system for centrifugal pumps
The latest version of the “motor-mounted” speed control system for centrifugal pumps was designed specifically to cater to heating and air-conditioning applications. The system makes it possible to reduce energy costs by matching pump output to actual demand. The parameters of PumpDrive Eco are set at the factory based on the specific pump and motor data. This reduces the time required for commissioning the unit.
The built-in wireless module allows users to connect to an iPhone via Bluetooth to communicate with the system and configure settings as required. The application makes maintenance much easier to coordinate and expedites commissioning of the pump as well as offers an option for managing application-specific data records. The iPhone app can be downloaded free of charge from the iTunes® Store.
A “commissioning wizard” in the app helps users set up and configure an open-loop control mode as well as discharge pressure and differential pressure control. A USB interface integrated in the service connector for direct connection to a PC enables fast data throughput.
The intelligent PumpMeter developed by KSB can be easily connected using the available bus system as an option. The sensor records the current suction, discharge and differential pressures as well as the discharge head and uses this information to determine whether the pump is operating in an energy-efficient manner.
In addition to PumpDrive Eco for motors with a rating of up to 11 kW, a variant with numerous additional design features will be offered for motor ratings up to 55 kW.
It can be mounted directly on a motor, on the wall or in a cabinet. It is the only variable speed system that can control asynchronous motors as well as synchronous reluctance motors.
