Product Description

Working Diagram:

The current problem
Condition monitoring of submersible vertical pumps to predict equipment health requires more innovative methods than have historically been available. Historically, vibration measurements for vertical pumps are taken at the motor. At this location, a clear picture of what is occurring at the hydraulic assembly below is rarely accurate.

Some challenges include:
• Damping from the pump foundation
• False readings from excitation of the above ground stationary assembly
• Distance from sources of vibration in submerged locations

A New Solution
Ronds has developed an innovative solution to permit monitoring of the below ground assembly of vertical pumps to provide a more accurate and complete picture of pump health.
Benefits
• Understand risk of operation for different operating conditions; seasonal changes, water level changes, process condition changes, etc.
• Significantly improved warning of problem conditions, resulting in lower cost of repair and better maintenance planning
• More valuable data for diagnosis and remediation of problems
• Ability to detect if stationary assembly mode shape is being excited during operation
• Interface with cloud-based storage and software allows remote access to data

Suggested Applications
• Service water
• Circulating water
• Condensate
• Cooling water
• Dewatering
• Pipeline Booster
