When a major beer brewer located in the Rocky Mountain Region of the United States came to Sundyne Corporation for help with their centralized high-pressure cleaning system, they had already experienced several failures with other pump manufacturers’ products. Working closely with the technical staff at the brewery, Sundyne Corporation engineers crafted a solution for them that utilized a pair of Sunflo P-2500 pumps. The pumps and centralized cleaning system are now operating flawlessly and the brewer is very satisfied.
The Situation Washdown demands within a busy brewery are very demanding on pumps. Often centralized high-pressure cleaning systems call for pumps to remain deadheaded at zero flow on standby until required by the user. Usually, demands peak toward the end of a typical work shift when workers are cleaning up their stations. Washdown services will go from zero demand to full capacity in a matter of only a few minutes, taxing the entire system.
The centralized high-pressure cleaning system in the brewery covers six floors within the facility and utilizes 90 individual pressure wands connected with flexible hoses. In this case, the brewer had used several other pumps in their system. With system conditions rapidly moving from low-flow deadhead conditions to full-capacity flow demands were too much for the various pumps used and failures were occurring far too often.
The Solution Sundyne Corporation engineers met with the brewery’s maintenance and engineering staff to find a solution. After gathering the necessary details, several recommendations were made to improve the centralized cleaning system at the brewery (see Application Brief for more details).
Central to the improvements were the addition of bypass lines to reduce stress on the entire circuit during low demand periods. The two Sunflo P-2500 units with newly designed outboard bearings designed for more harsh conditions were the perfect pump solution. Operating alone or in parallel the pumps now provide the necessary flow requirements during peak demand periods while handling the pump punishing effects of deadheading when flow requirements are at zero. Other improvements included new system settings for start-up, shut-down, minimum flow control, and second pump start-up.
The Result To date, the reliability of the centralized high-pressure cleaning system has made a complete turnaround. According to the primary contact at the brewery, “We’re having no issues at all, the pumps are still running great.” |
