Run in Phase
Despite very high precision, minimal manufacturing tolerances can not be avoided in
the manufacture of the bearings. This condition may generate noise during the start-
up phase of the pump. However, this is normal and does not pose a long-term
problem. During post-fabrication testing, all pumps are tested for performance,
concentricity and noise. The start-up phase can take a few days, depending on the
operating mode. The following figure clearly shows the difference between a brand
new bearing (left) and a bearing after the break-in phase (right). After the break-in
phase, these operating noises will almost disappear.
