Fiberscope Inspections


Fiberscope Inspections For Preventative Maintenance 

NASH CERTIFIED™ Service Technicians or Field Service Engineers perform on-site inspections utilizing fiberscope to examine pumps & compressors identifying potential issues, damage or unusual wear as a means of preventative maintenance. Fiberscope inspections should be completed every 12 months for equipment operating in regular conditions or every 6 months for equipment in harsh conditions such as cavitation or corrosion. 

Fiberscope, often referred to as borescope or videoscope, is a flexible optical fiber bundle with a camera and eyepiece used to inspect equipment internals or other difficult – to – reach places. 


Depending on the size of equipment and conditions, fiberscope inspections are 30 minutes, and several can be scheduled at one time to minimize disruption of operation. 

Before fiberscope inspections, equipment must be shut down and locked out with body plugs at the top and bottom of the pump housing and obstructive piping removed. Moreover, pump ports need to be opened and the liquid seal drained. While preparing for fiberscope inspection the required personal protective equipment must be worn. 

Performing fiberscope inspections, NASH certified technicians thoroughly examine critical, internal pump components. Inspections aide in identifying problems such as cavitation damage, corrosion, erosion, scaling, contamination, unusual signs of wear as well as recognizing existing issues and determining the cause of those issues.

Upon completion of fiberscope inspections, customers receive reports including photographs and notes concerning damage or potential damage. All of which are explained in detail by the technician with the intent to minimize additional issues and downtime. 

NASH certified technicians have over 25 years of experience inspecting internal pumps. Therefore, the team is well versed and trained to proactively address equipment concerns and schedule preventative maintenance in an attempt to reduce operational downtime and costly repairs.
