temperature: 350°C*
Type NMWB is a volute casing pump with housing dimensions according to ISO 2858 and magnetic coupling for thermal oil applications.
The pump has a permanent magnet coupling, and the containment shell hermetically seals the fluid to the outside.
The bearing housing with molded ribs is designed as a cooling piece. Thus, the temperatures in the gap pot area are significantly below the flow temperature in the spiral housing.
There is no internal circulation. The sliding bearing and a throttle section prevent the exchange of contaminated product with the clean medium in the magnet space.
The pump is not self-venting and must be vented with an open suction slide via a venting device.
The bearing of the pump shaft takes place in SiC plain bearings. Wear rings are standard on the suction and pressure sides.
In addition to the foot support, the spiral housings are also available with an axle-mounted suspension.
The direct mounting of the drive motor eliminates additional bearings and the mechanical coupling.
