    High-Performance Frequency Inverter for Pumps

Based on its performance frequency inverter family, Kostal has developed the INVEOR MP Pump, a device that is specially tailored to all requirements for use in pump applications. A special feature that distinguishes the MP Pump from other devices in the INVEOR family is the smart sensor. This acceleration sensor records vibrations in the application so that the recorded data can be used for predictive maintenance. This makes maintenance and servicing work more efficient and optimises the reliability and availability of the system. In addition, the INVEOR MP Pump has the option of connecting a PT1000 resistance temperature sensor. In this way, application-specific temperatures can be monitored and, depending on this, your pump can be protected or the control can be optimally adapted to the measured temperatures. 

Another highlight are three bidirectional IOs (two digital, one analogue) on the unit, which the MP Pump has received in addition to the standard inputs and outputs. These can be assigned as inputs or outputs as required and thus guarantee the greatest possible flexibility for integration into the customer's application. A pump display specially adapted to pump applications enables the control to be adapted on pump-specific process variables. For example, pressure or flow rate can be set directly on the unit.

Master-slave control for up to six pumps

The MP Pump is the ideal device for multi-pump operation. With its intelligent control, it scores points by controlling up to 6 pumps in a master-slave network according to demand. It ensures even wear of the pumps, taking into account the operating hours, and guarantees a constant supply pressure even with fluctuating delivery quantities. The auxiliary master function ensures high availability even if the master fails. At the same time, the fail-safety and reliability of the entire drive system increases.

Of course, the INVEOR MP Pump also has basic pump protection functions. The dry-running protection prevents a pump from continuing to run without pumped medium and thus protects against overheating and wear. Blockage detection allows blocked drives to be detected. An immediate shutdown and error message protects the motor and frequency converter. The MP Pump is also equipped with a PID controller as standard, which enables precise control to the desired process variable and thus contributes to energy saving, prevention of motor heating and ultimately to the reduction of wear.

High and low overload versions

As a performance device, the INVEOR MP Pump controls all motor types from the classic asynchronous motor to permanent magnet synchronous motors to highly efficient synchronous reluctance motors with maximum efficiency and high dynamics. This gives the customer maximum freedom in his choice of motor and ensures that he is also well positioned for future developments. The superior control technology of the INVEOR MP Pump enables very high starting torques as well as overloads of up to 200% and an extended speed control range of 1:200. For applications that do not require the highest overloads, the MP Pump offers low-duty variants in every size. These provide power in each size that would otherwise only be available in the next size up. This means that the customer can use the smaller size and save costs.
