Description

Canned motor pump type CAMh

The CAMh type is the specially adapted solution for CO2
applications.
As a high-pressure version, the CAMh is optimally adapted to existing
installation conditions and is suitable for 52 bar operation and standstill
pressure.

Type / design

Horizontal, seal-less section-type pumps with completely closed canned
motor, with radial impellers, multi-stage, single-flow.

Drive

The rotor lining, one of our core competences, is manufactured using the
compact extrusion method and as a nickel-base alloy, it is an essential
component of the highly efficient canned motor. The canned motor filled
with liquid accelerates to the operating speed in seconds. It is wear-free
and maintenance-free during continuous operation due to the hydrodynamic
sleeve bearings. The canned motor is low-noise and low-vibration and
offers double security against leakage.
