Design variants
Heated pump H1 and/or H2
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.
Inducer J
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.
