Applications
For domestic or industrial waste water, dirty water with solids up to 45 mm grain size for GMC and 50 mm for GMV, for liquids which are compatible with the pump materials.
Operating conditions
- Maximum liquid temperature: 35 °C
- pH value: 6-11.
- Maximum immersion depth: 10 m (with suitable cable length).
- Continuous duty (with submerged motor).
Features
- Safety: The double mechanical seal with oil chamber ensures safe separation separating the motor from water and providing further protection against accidental operation when dry.
- Reliable: The lower double ball bearing ensures high reliability under all operating conditions.
- Protection:
The three-phase motors are equipped with integrated thermistors, which provide the motor with thermal protection. The motor cable is pre-wired to enable the user to connect directly to a control panel, providing easier installation. - Flexible installation: The availability of the pump casing with horizontal or vertical flanged ports allows the installation of pumps in all pits and wells, both small and large sizes. Installation is also possible with a duck foot coupling.
