Abstract

THE PRESENT INVENTION RELATES TO PUMPS COMPRISING VARIABLE FREQUENCY DRIVE MEANS AND METHODS FOR OPERATING SUCH PUMPS. THE INVENTIVE METHOD FOR OPERATING A PUMP (1) COMPRISES THE STEPS OF, OBTAINING VALUES OF OPERATING PARAMETERS OF THE PUMP INDICATING PUMP CONDITIONS, COMMUNICATING SAID VALUES OF OPERATING PARAMETERS FROM VARIABLE FREQUENCY DRIVE MEANS (2) TO A CONTROL DEVICE (11), DETERMINING IF A PREDETERMINED CONDITION IS FULFILLED, COMMUNICATING INSTRUCTIONS FROM THE CONTROL DEVICE TO THE VARIABLE FREQUENCY DRIVE MEANS, BASED ON THE FULFILLMENT OF SAID PREDETERMINED CONDITION. FURTHERMORE, A COMPUTER PROGRAM PRODUCT LOADABLE INTO A MEMORY OF A DIGITAL COMPUTER DEVICE INCLUDING SOFTWARE CODE PORTIONS FOR PERFORMING THE INVENTIVE METHOD, A PUMP, A PUMP SYSTEM AND A CONTROL DEVICE FOR A PUMP ARE DESCRIBED.
