Case Studies & Literature

& Troubleshooting

To help our customers solve complex issues with critical pumping equipment, Hydro’s Reliability engineers bring an array of technology to the site to help you get to the bottom of the issue. These issues may be related to a pump, gear box, motor, or operating system.

Hydro utilizes technology such as Operating Deflection Shape and Experimental Modal Analysis along with flow, power, and pressure monitoring. Hydro has the experience to resolve these issues.


Health Audits

Hydro performs on-site health audits (or mechanical/hydraulic evaluations) on customer pumps and drivers. These audits include flow, vibration, temperature and mechanical condition inspections to help determine the overall condition of the equipment. These tests can be performed either before or after an equipment overhaul to help end users to better plan and prioritize for equipment down-time, as opposed to "running to failure.”

Uncover Underlying Issues With Your Critical Equipment

Hydro Reliability Services predictive and proactive approaches provide customers with troubleshooting and health audits to arrive at expert solutions for your rotating machinery challenges. Backed by over 50 years of experience, Hydro’s reliability engineers delve into the root-cause of pump issues and develop detailed job scopes for creating top-performing and long-lasting equipment. Being independent and unbiased allows Hydro to work on all makes and models of pumps.

Customer Success Story

Hydro Reliability services was called into a combined-cycle plant to determine the condition of the plant’s two condensate pumps. Losing one of the pumps to failure would cause the plant to be vulnerable to unplanned downtime and huge expenses.

In concert with various Hydro divisions, Hydro Reliability Services was able to perform a health audit to identify performance issues, establish root causes to those issues using modal analysis, test solutions to the issues using finite element analysis, implement structural modifications to address those issues, test the effectiveness of those modifications using performance testing, and monitor performance of the pump in the field with wireless condition monitoring.

Hydro has the knowledge, experience, and technology to resolve these types of pump issues within the workshop and the field, which positions us as a total solutions aftermarket pump company.
