LDT Dosiertechnik GmBH, a leading supplier of pumping solutions, has expanded the DOSEURO product range it offers to include the innovative RAPIDA motor inverter.

The RAPIDA system offers users an easy way to vary the flow rate of the high performance DOSEURO pump range, making them an even more versatile solution for many applications.

Motor frequency of the RAPIDA system can be varied between 6 and 60 Hz to give a proportional flow rate of between 10 and 100% of pump capacity.

The frequency can be set either locally at the motor via an easy to use integrated LCD display or remotely using a 4-20mA signal. The local display can be set to show motor frequency in either % or Hz.

Alongside easy adjustment of flow rate, the RAPIDA motor inverter also has additional features that help keep processes running smoothly, including the ability to connect a level sensor to automatically stop the pump when a defined level is reached; a local alarm display for overvoltage, under voltage, temperature, overload and underload; and a relay output for remote alarming purposes.

A diaphragm rupture detector is also available for use with SD type pumps. This feature will automatically stop the pump in case of diaphragm failure and send an alarm signal to the operator.

The motor offers further application versatility as it can be programmed to operate in a batch control mode so that the pump operates only for a certain period of time, configurable between 1 and 9,999 minutes.

The RAPIDA motor inverter system is available with SR type A, D, B, BR and SD DOSEURO pumps. The unit can also be easily retrofitted on site for existing pump installations.

The unit offers real benefit and versatility for use in many different applications and is a welcome addition to the LDT Dosiertechnik solutions portfolio.

LDT Dosiertechnik supports the wide portfolio of solutions it offers with expert pumping knowledge, detailed understanding of a wide range of applications and comprehensive project and aftermarket services.

It engineering teams are committed to understanding operational goals and ensuring its customers get the optimum pump performance for their installation.
