A Positive Displacement Pump is a pump that draws in a certain volume of fluids and has the same amount of fluid leaving the discharge side of the pump, therefore, maintaining a constant flow for pumping operations. At Tapflo we supply a variety of Positive Displacement Pumps depending on your application.
There is often a debate as to whether you should use a Positive Displacement Pump or a Centrifugal Pump, however, both have their strengths and weaknesses depending on your application. We recommend using a Positive Displacement Pump if you are handling high viscosity fluids, high pressures or require a low flow rate. If you’re unsure whether a Centrifugal Pump or a Positive Displacement Pump would suit your application better, then get in touch with the Sales Team today, we’d be happy to talk you through your options.
We supply a wide range of Positive Displacement Pumps, each of which has its own benefits…
Our Diaphragm Pumps are air operated, they have 2 diaphragms inside, 1 diaphragm creates a vacuum to draw fluid into the pump whilst the other forces fluid out of the discharge port.

Lobe Pumps are a versatile pump designed for sanitary applications. The pump is operated by two rotating lobes that create a suction to draw more fluid into the pump, creating a pressure that causes a predetermined amount to flow out of the pump’s discharge port. For additional information visit our Quick Guide to Pomac’s Sanitary Lobe Pump.
The Twin Screw Pump has been designed to combine all the benefits of a Lobe, Peristaltic, Centrifugal and Circumferential Piston pumps. We supply Screw Pumps with double screws, which rotate to move fluid forward through the pump casing.
Also known as a Flexible Impeller Pump, these pumps push liquid forwards within the pump by trapping fluid between each vane of the impeller.

A Peristaltic Pump is a versatile pump that is easily maintained due to the main wear in the pump only affecting the hose. The pump creates a pulsating flow created by shoes or rollers on the wall of the hose to push fluid along the hose.
