Motor inverter added to portfolio

Motor frequency of the RAPIDA system can be varied between 6 and 60Hz 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 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 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 will automatically stop the pump in case of diaphragm failure and send an alarm 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 9999 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.
