DESIGN VARIANTS
The pumps are outfitted with a heat jacket and pump casing (H1) and/or a heat jacket in the bearing lantern (H2). Both heat jackets can be realized either separately or in conjunction with a bypass line. The heat jackets in the standard construction are rated for operating pressure of 16 bar at 200 °C (steam) or 6 bar at 350 °C. The heat jackets can also be used for cooling.
When solids-containing liquids are being transported, the internal filter prevents inadmissibly large particles from entering the flow channels, and from there the magnetic coupling and internal bearings.
These external connections allow for external flushing, feeding and/or venting. Connection E1 is used in situations where a continuous feed into the magnet drive is desired. Connection E2 is used suitable for short-term flushing, or for external venting of the magnetic coupling.
The double isolation shell should be used in situations requiring a high level of safety. The unit consists of two interlocking isolation shells, both of which are rated for the relevant operating conditions. If one of the two units is damaged, the casing still remains leaktight. The gap between the two units can be monitored.
Inducers are often used in cases where the installation’s NPSH values are extremely low. Inducers substantially reduce pump NPSH throughout the installation without altering pump characteristics. Inducer J can be retrofitted on existing pumps, in most cases with only a minimum amount of pump modification.
