Centrifugal Pump

Article sections

    Tapflo supply a number of different pumps, one of which is a Centrifugal Pump. The Tapflo Team have put together a list of frequently asked questions and a case study using a Centrifugal Pump to ensure you make the right decision when selecting your pump!

    Can I let my Centrifugal Pump run dry?

    Running a Centrifugal Pump dry is a big no. The design of a Centrifugal Pump means that running it dry for even short periods of time will destroy your mechanical seal and potentially burn out your motor. To stop this, you should always install standard Centrifugal Pumps with flooded suction, unless you’re using a Self-Priming Centrifugal which is a fundamentally different design. If running dry is a risk during your process, you should consider installing some form of Dry Run Protection.

    What is BEP (best efficiency point) and why is it important?

    Best Efficiency Point is crucial at the time of selection; ensuring the pump is matched to the application will assist with long operating life. When a pump operates at BEP, it is at its most efficient, meaning the pump is using input power as efficiently as possible and reducing energy costs. When a pump operates at BEP it also produces the lowest vibration readings, meaning that pump longevity is increased and maintenance costs are decreased – something all users should be focused on when selecting the right pump.
