Q'ty :

The operation and interval time of CEVB are controlled by PLC.
CEVB has to work with volume distributors to deliver the metered quantity of oil to the lubrication points.
CEVB has a pressure gauge that enables the user to check the operating pressure easily.
CEVB has an 8kgf/cm² NC contact socket pressure switch that detects the operating pressure automatically and sends a signal when the pressure is below the preset value.
CEVB has a NC contact float switch that detects the oil level automatically and sends signals when the oil level is low.
CEVB has a pressure-regulating valve that enables the user to adjust the operating pressure.
The gear pump of CEVB is made of special aluminum alloy and assembled with the induction motor to provide stable output pressure, low operating noise, and long service life.
CEVB can be added with the following parts on request.
● A feed-oil button can be used for manual oil feeding.
● An indicator light that shows when CEVB discharges oil.
