Blackmer, part of PSG, a Dover company and specialist in positive displacement, regenerative turbine and centrifugal pumps, has created a new video about cavitation.
The video illustrates why cavitation occurs, the potential harmful effects it has on pumping components and possible solutions to avoid this common pumping challenge. You can see the video here.
Blackmer says that its Cavitation Suppression Liner is able to deal with the challenges of excessive cavitation. Available as a component on Blackmer CRL, LGL, SGL, XL, XLW and TLGF Series sliding vane pumps, the Cavitation Suppression Liner has been specifically developed to eliminate the vibration, excessive noise and pump-component damage that results from cavitation.
Its design creates internal recirculation jets that break apart vapour bubbles before implosion. While the vapour levels are not reduced, the size of each vapour bubble becomes a fraction of what it would have been. The Cavitation Suppression Liner also allows a controlled amount of fluid at discharge pressure to bleed back toward the suction of the pump. This breaks the larger vapour bubbles into smaller ones before they can implode. The result is less noise, less vibration and less wear.
