Sunair’s Commitment to Client Excellence

When the managers of an oil refinery in the Northeast sought to rerate and optimize one of its process units, they were limited by an existing, legacy pump with a much higher minimum continuous safe flow rate than required.

They turned to Sunair Co. and our partner Sundyne—a premier designer and manufacturer of industrial pumps and compressors for the process fluid and gas industries—for the best solution.

The Problem

The refinery was having problems running their existing pump at the preferred flow rate, resulting in premature failures and reduced production efficiencies.

To make matters worse, the existing piping wasn't compatible with the recommended pump for the job—a low flow Sundyne SMKL horizontal overhung API 610 OH2 model. Having worked with Sundyne’s SMKL pumps before, the plant reliability engineers and operators knew it would provide the precise flow rate they were seeking to achieve, but required additional assistance to implement the new pieces of equipment.

The Solution

Sundyne worked with the refinery to design and cast a custom volute so the pump could replace the old model, without requiring expensive piping modifications.

The Result

The plant was able to quickly install the pump, avoiding any unscheduled downtime or unexpected outages. The new, custom volute also averted a costly retrofit.

Within hours, the plant was back up and running, with process unit rates adjusted for optimal performance, and the pump operating at desired flow rates. The upgrade has resulted in improved pump reliability, higheruptime, and enhanced production.

The commissioning process went smoothly, and the unit’s spare is currently in production, to safeguard against future potential unplanned downtime. Sunair Co. and Sundyne are now looking forward to evaluating additional opportunities to upgrade, rerate, or retrofit other existing assets at the facility.
