DRAIN SS 304

Submersible pumps in stainless steel for clean or sligthly sandy water, 2 poles, from 0.55kW to 1.1kW,
Max head: 13 m,
Max capacity: 440 L/min

 

Description

Pumps in stainless steel AISI 304 for drainage. Thanks to their light weight these pumps are ideal for small drainages when it is necessary to move the pump frequently.

Use

The DRAIN SS 304 are usually used to drain clean or sligthly sandy water from ponds, foundations or after floods even if water contains stones. These models cannot be used to pump sewage water.

Operation conditions

Max liquid temperature: 50 °C (122 °F)

pH: 6-13

Max density: 1000 kg/m³

Max immersion depth: 5m

Standard 90° plastic connection 1"1/2 or 2" in one piece supplied as a standard with the pump
Coupling foot MODEL 1-1/2" or MODEL 1-2": automatic coupling foot with 1"1/2 or 2" connection 
No-return valve Professional ball check valve threaded 1/2" or 2" in cast-iron
Float-switch 10 or 20 metres cable float-switch to be connected to an electric board in case it is not possible to use the standard float-switch connected to the pump
Electric board Model F5-0.5/3-1 for single-phase pumps or model F6-0.5/10-3 for three-phase pumps. 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. In the three-phase pumps (that have no protection built-in into the motor and without the possibility to connect a float-switch directly on the pump) the electric board is mandatory.
