SEMISOM GR with grinder
Submersible pumps with grinder recommended for domestic, civil and industrial installations. The blades, in forged and tempered stainless steel, allow to chop the solids and filaments in the waste or sewage water and thus to expel them even through relatively small pipework and/or when high head is required.
Application
They are recommended to pump waste water coming from domestic, civil and industrial installations as well as draining septic tanks.
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.
- Semisom 125 GR: double seal with interposed oil chamber.
- Semisom 300 GR: back-to back double mechanical seal with oil chamber in-between protected by V-Ring seal, double row ball bearing on the pump side.
- Resin-insulated cable kit to prevent penetration of water inside the motor.
