Conical progressive cavity pump ensures longer service life
Progressive cavity pumps are a proven solution for situations where viscous media need to be pumped against high pressures , especially when the media to be conveyed are often abrasive . Although this type of pump is suitable for these media , it has become more durable over time thanks to design modifications and the development of more wear-resistant materials and coatings . However , in practice , the wear parts of a progressive cavity pump often have to be replaced several times over the course of its life cycle . A new type of progressive cavity pump featuring a conical rotor and stator now offers longer service life , lower life cycle costs and increased energy efficiency .
