Submersible Semi Vortex Pumps Ebara DVS Series


FEATURES :

  • Semi vortex impeller
    The semi-vortex impller offers non-clog operation and high pumping efficiency. Allows pumping of waste water containing foreign matter as large as 60 – 70% of discharge size
  • Easy maintenance
    Due to semi-vortex design with no strainer or close tolerance suction cover, only 3 or 4 bolts need to be removed for quick and easy maintenance
  • Double mechanical seal in oil chamber
    An oil lubricated double mechanical seal with lower faces of hard silicon carbide provides strong and reliable shaft sealing
  • In built motor protection
    Quick acting dual response overloads provides protection against overload, lock or open phase
  • Automatic operation
    All models up to 3.7 kW are available as automatic (A’ type) or parallel alternating (J’type) pumps with inbuilt control and float switches. No need for separate control panels, simply connect to power source
