Included within Tapflo UK’s pump portfolio is a range of Centrifugal Pumps to suit a variety of applications. Our team have put together a few frequently asked questions and a case study which features a Centrifugal Pump to ensure you make the right decision when selecting your pump!
How does a Centrifugal Pump work?
The impeller within the Centrifugal Pump casing turns which creates a centrifugal energy source at the centre of the impeller which is on the rotating axis. This draws liquid in through the inlet and flows round due to the pressure within the casing which then drives the liquid out of the pump’s discharge port following the operating direction of the axis.
What applications are Centrifugal Pumps suitable for?
Centrifugal Pumps are suitable for a wide range of industries and applications including but not limited to:
- Food & Beverage – dairy, edible oil, juice, chocolate, CIP
- Wastewater Treatment – sludges, dosing acids, alkalis
- Photo Processing
- Surface Treatment
- Industrial Water Supply
Can I let my Centrifugal Pump run dry?
Definitely not. 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.
