Widethroat Progressive Cavity Pumps

Roto Wide throat inlet design enable gravity flow of high viscous (plastico-viscous) materials onto the auger-on-coupling rod, which then pushes the substances to the pumping element. Wide throat pumps, equipped with a twin paddle bridge breaker at the top, are engineered to handle extremely difficult media with very high solid content and non-flowing properties.

These pumps are available in close-coupled and bare shaft configurations, with custom-designed hoppers available upon request. A variety of construction materials and shaft sealing options are also offered.
