SAND 100

Submersible pump in cast-iron for sandy and drainage water, 2 poles, 0.75kW,
Max head: 13 m
Max capacity: 300 L/min


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 100 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 and the capacitor 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.


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.
