Product description
Application
The H Series is used to pump clear water or light sewage where high pressure is needed. This series particularly suited to pumping water for fountains, waterparks, agricultural irrigation and farming.
Characteristic
All main components are made of grey cast iron GG25. Two individual mechanical seals (motor side in the oil chamber, impeller side in contact with the liquid) and high quality parts, ensure the perfect functioning and reliability of the product.
Motor range
- Squirrel cage motor at 2 poles
- Thermal protection T1 and T2 embedded in the motor winding (to be wired to the three pole contactor in the control panel)
- Class F insulation (155°C)
- IP 68 protection
Motor cooling
The cooling of the motor is ensured by the liquid where the pump is submerged.
