SR series 400

SR series 400

Monobloc, multistage submersible pumps for installations in domestic, agricultural, civil and industrial environments.

Application

These electric pumps can suck liquid up to few centimetres from their bottom; they are consequently the ideal items to move clean water from tanks or rainwater harvesting.

Construction

  • Shafts machined on ball bearings and mechanical seals location.
  • Coolant filled rewindable electric motor with phase insulators to protect the motor from power peaks, as a guarantee of a highly-trustworthy product.
  • Double seal and oil chamber in-between.
  • Resin-insulated cable kit to prevent penetration of water inside the motor.
