TECALEMIT’s Bulk Fuel Transfer Pump
Two Types – And Which You Should Use
The two most common types of pumps used in our builds are positive displacement pumps and centrifugal pumps. You might be wondering, what’s the difference?
Positive displacement (PD) pumps operate by trapping a fixed amount of fluid and then forcing it through the pump’s discharge port. These pumps have a constant flow rate regardless of the pressure, and they are suitable for pumping high viscosity fluids or fluids with a high solid content. In this case, we would use a PD pump on a PRO-5000, for example, for bulk transfer or bulk refilling applications.
Centrifugal pumps, on the other hand, work by using a rotating impeller to create a flow of fluid. The impeller’s rotation creates centrifugal force that pushes the fluid outwards, towards the pump’s discharge port. Centrifugal pumps are suitable for pumping low viscosity fluids at high flow rates. This type of pump would be our Hornet W85, our continuous duty cycle pump, which comes with most of our refueling systems and is intended to quickly fill your trucks or smaller tanks and totes.
Each type of pump has its own advantages and disadvantages, and the choice of pump depends on the specific application requirements. Be sure to speak with your sales rep so they can help you build out your bulk fuel system!
