PumpSmart® Variable Speed Drive System


    (Seneca Falls, NY) ITT’s PumpSmart is the powerful combination of a standard variable speed drive and over 150 years of pump hydraulic design and pump process knowledge. By leveraging commonly available information through the variable speed drive such as speed, power and torque PumpSmart provides key pump performance indicators which maximizes control and reduces energy consumption over a standard variable speed drive.  PumpSmart’s patented features which can not be found on a standard variable speed drive include:

    1. SmartFlow™, Sensorless Flow Measurement – With out any sensors PumpSmart can derive the flow of the pump with in ± 5% of the rated pump flow.  With only four pieces of pump performance data required PumpSmart is able to calculate the flow of the pump by comparing the pump power and flow performance curves.  SmartFlow can be used on any manufacturer’s centrifugal pump and a self calibration function allows for correction due to pump wear.
    2. Pump Protection – Because PumpSmart knows exactly where your pump is operating on the performance curve it will inform and protect the pump from conditions such as dry running, low flow recirculation and no-flow. All of which are detrimental to pump reliability.  
    3. Multi-Pump Control – Managing multiple pumps with a standard variable speed drive is a very challenging task given the breadth of process variables, speed, flow and pressure of multiple pumps.  PumpSmart’s embedded logic will manage the entire process from balancing flow between pumps, rotating pump operation for even wear to providing automatic fault backup.  No PLC is required; configuration is performed on-site and can be adjusted by the end user to meet changing system requirements. 
    4. Pump Cleaning Sequence – PumpSmart is continuously monitoring the performance of the pump and is able to detect when a pump has become clogged or jammed.  Upon detection PumpSmart’s Pump Cleaning Sequence takes action by cycling the pump forward and backwards at different speeds and velocities creating the forces necessary to free the pump from a clog; thus eliminating the need to manually un-clog the pump.
