SR series 330
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.
