Series VBR, with integrated overflow valve and bypass

The VBR industrial pump program is characterized by a robust and durable construction and can be used for a variety of applications. The pumps are ideal for pumping clean or slightly contaminated media such as cutting oils, cooling lubricants, hydraulic oils, lubricating oils, motor oils, gear oils, kerosene, petroleum, glycol, heating oils, solvents, bitumen, additives, fuels, heavy oils, (bio) Diesel, but also thermal oils and vegetable oils. This makes the series suitable, for example, for dosing systems, machine tools, power plants or drying systems and much more. The industrial pumps of the VBR series have an integrated overflow valve and bypass, which ensures that a set maximum pressure is not exceeded. This relieves the pump in the direct bypass into the suction side.

Technical Data:

Details

  • Self-priming
  • self-lubricating
  • practically non-pulsating, quiet-running,
  • practically maintenance-free, pressure-proof and vacuum-tight shaft seals
  • Discharge range: 45 to 6700 l/h
  • Operating pressure: 0 – 40 bar
  • Temperatures: up to 150°C (higher temperatures on request)
  • Direction of rotation          I = indirect – counterclockwise

                                         D = direct – clockwise
The direction of rotation can only be changed in the factory. Therefore, specify the desired direction of rotation as viewed from the pump shaft as per dimension sheet when ordering.

Areas of application

  • Mechanical engineering
  • Construction
  • Energy
  • Agriculture
  • Marine / offshore

* To ensure the pump is working properly, the pipes must be scaled according to the principles of fluid dynamics by calculation of line according to the local requirements.
The pump or device connection gives no indication of the relevant size of the pipe.
