Reduce unplanned downtime and minimize repair costs with expert predictive maintenance by Philadelphia Mixing Solutions’ Aftermarket Services

THE PROBLEM: A large metropolitan municipality in Texas had 120 mechanical mixers at five Wastewater Treatment Facilities spread across its jurisdiction. The maintenance team was finding it difficult to keep up with preventative maintenance of the mixers after facing budget reductions. As a result, the mixers were falling into a state of disrepair.

THE SOLUTION: Philadelphia Mixing Solutions offers comprehensive aftermarket programs to understand current mixer fleet health, implement preventative maintenance programs to reduce unplanned downtime, and reduce the frequency and cost of equipment overhauls.

CHALLENGE: The municipality did not have the manpower, expertise, or equipment to remove, repair, or install mixing equipment, making them dependent on general contractors and local repair facilities. The result was high in/out costs coupled with decreased repair quality, and being at the mercy of a 3rd party for scheduling of equipment installation, repair, and removal.

PMSL’S SOLUTION: PMSL developed a Mixer Maintenance and Repair Services contract, which included installation, removal, and repair. The contract allowed the municipality to control the costs and quality associated with routine maintenance, in addition to the overhaul of any mixers requiring repair.

Additionally, PMSL field service technicians performed regular equipment predictive and preventative maintenance checks to make sure all equipment was properly maintained and evaluated to OEM standards. The regular checks included visual inspections, noise assessment, vibration assessment, and oil analysis. The data collected during the checks was regularly reviewed by PMSL’s team of mixing and gearbox industry experts and consolidated into a bi-annual health assessment to highlight any mixers in need of attention.

All repairs were performed utilizing the Premium Repair component of PMSL’s Inspection & Repair Program, which includes Coordinate Measurement Machine (CMM) validation of all critical manufacturing tolerances and advanced root cause failure analysis. The Premium Repair Option restored the aerators to “like new” condition, ensuring they will stand up to the rigorous demands of the surface aeration application, while providing peace of mind with a full one-year warranty.

BENEFIT TO THE CUSTOMER: Many years after initiating the Mixer Maintenance and Repair Services Contract, this customer now has the peace of mind that their equipment is being closely monitored by the industry leading experts. Predictive maintenance highlights any problems with the mixing equipment before catastrophic failure, reducing unplanned downtime and minimizing repair costs. By providing a unique solution for this customer, PMSL helped this Municipality enhance its reliability through modernization, all while minimizing the logistics and costs associated with the maintenance and repair of the mechanical mixers.
