Spirax Sarco’s Pivotrol pressure-powered pump cover and mechanism retrofit is offered as an in-line, bolt-in upgrade for mechanical pumps. Provided with full warranty coverage at 200 PSIG operation, the retrofit is designed as a solution to excessive maintenance and energy consumption, heat exchanger stall, waterhammer, and erratic steam system performance. The technology is designed to replace conventional pins and linkages with pivots, which reduces friction and wear and lengthen service life.
