The PFA-Lined gear pumps series offer a durably constructed outer stainless Steel body with a heavily layered Fluoro-Polymer (PFA) internal lining. This highly chemically resistant PFA lining is mechanically attached and bonded to the internal stainless steel surfaces using a specialized molding process, effectively isolating the fluid being pumped from any metal surfaces. Fluoro-Polymers exhibit the highest corrosion resistance of any plastics. This combination of stainless steel on the outside and Fluoro-Polymer on the inside gives the Poly-Guard™ the full strength and integrity of a metal pump with the ultimate corrosion resistance of a Fluoro-Polymer. Since 1972 our gear pumps (Verdergear Process) are produced from the renowned manufacturer Liquiflo in the United States.

Gear pumps

The Verdergear pump range offers excellent solutions for high viscous fluids. The pumps are available with several other build options such as heating jackets, relief valves, special materials, base plates and more. A gear pump, is often used for pumping viscous liquids, but is also suitable for other applications. The pumps are excellent for handling of fluids of any viscosity that require a gentle, pulsation-free flow. Liquids with solids, lubricating as well as non-lubricating, Verdergear pumps are an excellent solution. Some applications are the transfer of chocolate and starch.
