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.
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.
