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 inspections
Fiberscope, often referred to as a 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.
Shutting down equipment
While preparing for fiberscope inspection the required personal protective equipment must be worn
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.
Component examinations
Performing fiberscope inspections, NASH-certified technicians thoroughly examine critical, internal pump components.
Inspections aid in identifying problems such as cavitation damage, corrosion, erosion, scaling, contamination, and unusual signs of wear as well as recognizing existing issues and determining the cause of those issues.
Reports
Upon completion of fiberscope inspections, customers receive reports including photographs and notes concerning damage or potential damage. All of these 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.
