    This will allow the pump's bearing to be monitored continuously. Especially for high pressure applications where high axial forces dramatically limit the bearing lifespan, vibration monitoring will prevent unexpected downtime with planable preventative maintenance, making ViscoTwin high pressure pump setups a highly sustainable solution.
