The performance of a corrosion protection coating is significantly influenced by its ability to adhere to the substrate material.

Texas A&M WWTP was unhappy with the progressive cavity pumps used to transport sludge. These pumps required a great deal of space, and maintenance and service was difficult. This meant the entire pump needed removal when performing major repairs. In addition to leaks of gland seals, there was also frequent dry running problems, which required time consuming and expensive repairs to the stator and rotor.
The wastewater treatment plant selected Vogelsang rotary lobe pump VX136-210Q with saddle design, which fits perfect to the limited space, offered the advantage to reverse the pump direction and that was capable of constant delivery rate even for fluids with high dry matter content in other words highly viscous sludge.
