SUPERSAND N 2000

Submersible pump in stainless steel for sandy and muddy water, 2 poles, 15kW,
Max head: 44 m,
Max capacity: 2.600 L/min

Description

Pump in cast-iron and stainless steel AISI 304 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 the SUPERSAND N 2000 is a pump ideal also for hard applications.

The impeller and the volute of the impeller are in cast-iron with an high percentage of chrome to grant an extremely high resistance against abrasion.

Use

Suitable for sandy water and muddy water. This model is usually used by contractors to drain water by the foundations or to dewater small ponds. Thanks to its upper discharge this model can work even if the water level is low (up to 170mm from the ground). 

Operation conditions

Max liquid temperature: 40 °C (104 °F)

pH: 6-13

Max density: 1100 kg/m³

Max immersion depth: 30m

Optionals:

Treatment Epoxy-bituminous coating to protect the pump against salty water corrosion and to increase the resistance against abrasion
No-return valve Professional ball check valve flanged 6"-DN150 in cast-iron
Float-switch 10 or 20 metres cable float-switch to be connected to an electric board
Electric board Professional electric board model F1-20-3 with metal case. The electric board provides a manual reset thermal protection to protect the motor of the pump and it permits the connection of a float-switch. Moreover the electric board verifies the lack of one phase or the invertion of two phases. The use of an electric board is mandatory.
Reverse switch Very small control box positioned near the end of the feeding cable that permits, turning a switch, to reverse the turning sense of the pump. This item is particularly useful when in a contractor site the pump must be moved in different positions and connected to different plugs: the reverse switch permits to set correctly the turning verse of the pump without changing the electrical connection of the phases.
