Hermetically sealed, all-ceramic chemical pump
The MPCV centrifugal pump is self-regulating, can run dry and is hermetically sealed. Therefore, this vertical pump does not require a minimum volume flow or a large static head. The three-phase-compatible pump is now also available as an all-ceramic version, the K-MPCV-AN (photo). The use of silicon carbide ceramic further extends the service life of the pump. Equipped with a magnetic coupling and roller bearings, which are permanently dry-running, the intrinsically safe K-MPCV-AN operates without bearings in the pumping liquid. The shaft-gap seal concept is based on the complete hydrodynamic relief of the bearing and seal unit. Back vanes and a gas barrier prevent product vapors from penetrating the bearing unit. Like all pumps in the V-AN range, the K-MPCV-AN features control characteristics that adapt automatically to variable feedrates. Hall 8, Stand C1 — Paul Bungartz GmbH & Co. KG, Düsseldorf, Germany
