SAND 300
Pompa sommergibile in ghisa per drenaggio di acqua sabbiosa, 2 poli, 3.0HP,
Max prevalenza: 21 m,
Max portata: 670 L/min
Description |
Pump in cast-iron for drainage. The suction grid at the base permits to position the pump at the bottom of a pond or of a hole into the ground as the stones and other solid parts cannot be suck by the pump. Thanks to its heavy duty construction and the top quality oil bathed motor the SAND 300 is a pump ideal also for hard applications. In case an electrical problem occurs, the reparation of the pump is extremely easy because the electric connections are positioned under the cover and completely isolated from the motor; so if some water enters into the pump from a cut in the cable the motor will be safe. |
Use |
Suitable for drainage water and sandy water. This model is much used by contractors by construction sites to drain water from foundations or to dewater small ponds. |
Operation conditions |
Max liquid temperature: 50 °C (122 °F) pH: 6-10 Max density < 1100 kg/m³ Max immersion depth: 5m |
