SBEL-LL(SBJ-FL) Series

SBEL-LL(SBJ-FL) series gear pumps are designed for use with extruders. In plastic film and sheeting manufacturing, it is important to control extruder unit pressure fluctuations and prevent temperatures from increasing. As a result, SBEL-LL(SBJ-FL) series pumps are used to improve the quality of extruded products.

 

Features

  1. Small pressure pulses.
  2. Since friction losses are minimal, heating of polymer is minimized.
  3. Can be used in situations where suction pressure is higher than discharge pressure.
  4. Shaft seals use a polymer seal (labyrinth seal) that minimizes leakage and contains no wearing parts.
  5. Heating is via an easy-to-operate cartridge heater that does not need to be removed, even for maintenance, thereby minimizing heater damage.
