Due to its tight internal clearances, it can be a challenge to adequately CIP a CP pump. Rotors can be removed, but as we mentioned in Part 1, there are costs and risks involved.

Choosing a pump design that minimizes the length of dead-leg to reach the affected area increases your ability to CIP the pump. 

It is common practice to remove positive displacement pump rotors for clean-in-place (CIP) preventative maintenance.

This practice and cause many problems:

• Damaged parts
• Worker injuries
• Product contamination
• Improper re-assembly

With a properly designed PD pump and CIP system, you can avoid these problems.
