Horizontale Kreiselpumpe Edelstahl UP
stainless steel
with mechanical seal
normal priming

UP Series

These normal-priming centrifugal pumps in close-coupled design with single mechanical seal are robust, durable and solid. Designed for temperatures up to 150 °C, they also handle media with metallic particles.

In pumps of the UP series, we transmit the motor power directly to the pump impeller by a fixed shaft. Therefore these pumps operate without slippage. The mechanical seal is lubricated and cooled by the pumped medium. All seal rings and elastomers are available for the UP in various materials. This allows us to easily adapt them to different applications. The spring of the pump is made of Hastelloy C4. The UP series is also available as UP-EX variants if required. Thus, its use is also possible in ATEX zones 1 and 2. more ...
