Remarks
  1. CENB has a timer that controls its operation and interval time. The control box has a built-in buzzer that sends an alarm sound when the oil level is low. The control box also has four indicators, operation (ACT), alarm (ALM), immediate lubrication (RUN), and interval (INT).
  2. CENB has to work with volume distributors to deliver the metered quantity of oil to the lubrication points.
  3. CENB can memorize the set value of operation time and interval time.
  4. CENB has a pressure gauge that enables the user to check the operating pressure easily.
  5. CENB has a NC contact float switch that detects the oil level automatically and sends signals when the oil level is low.
  6. CENB has a pressure-regulating valve that enables the user to adjust the operating pressure.
  7. CENB has a feed-oil button (F button), which can be used as manual oil feeding for less than 3 minutes to avoid overloading the motor.
  8. CENB with 3L above tank has an 8kgf/cm2 NC contact socket pressure switch that detects the operating pressure automatically.
  9. The gear pump of CENB is made of special aluminum alloy and assembled with the induction motor to provide stable output pressure, low operating noise, and long service life. It meets the requirements of most large machines.
