ST-2™ Multi Stage Anti Cavitation Trim

Email A Colleague

Trimteck’s ST-2 Multi-Stage anti cavitation trim not only eliminates cavitation damage, but it often prevents cavitation from occurring altogether.

By reducing pressure through a series of restrictive channels and expansion areas, it prevents vapor bubbles from forming and minimizes hydrodynamic noise. The ST-2 Multi-Stage cartridge consists of concentric cylinders of drilled holes and grooved channels; the expansion and contraction of the fluid from channels through holes and back into channels creates a series of pressure drops that eliminate cavitation in most applications, and reduce cavitation damage in others.
