14 Inch Anti-Vortex PVC Plate Assembly composition_Chlorinated Rubber They include stainless steel springThis 14 inch anti vortex plate prevents the formation of a vortex and subsequently air entrapment into the pump by forcing any emerging vortex to go around a plate and then into the suction pipe. The swirling motion cannot be maintained and the vortex dissipates and cannot form if the path is too long and contorted. This schedule 80 PVC Anti Vortex plate is a simple, effective product that controls velocity on your suction line and avoids cavitation.
