Nocchi Sub 3S Immersible Water Pump 0.8kW (111005)

The SUB 3S submersible pump is designed for pumping water from wells and open water reservoirs.
The pump is intended for pumping clean water without abrasive impurities (fine quartz sand, dolomite ash, clay).

Application:

Supplying private houses and rural estates with water from wells, watering gardens, filling reservoirs.
The pump can operate in automatic water supply mode if connected together with a pressure tank, pressure switch, and pressure gauge.

Construction:

The pump housing and shaft are made of stainless steel. The pump impellers are made of NORYL. The motor has hermetically sealed bearings, which ensure the pump's long-term operation underwater.
The pump is cooled with the help of the pumped water.
The pump is equipped with a 10m long four-core power cable.

Installation:

The pump should be submerged to a depth that allows it to operate at least 0.5 meters below the water surface, but not less than one meter from the bottom of the water intake. The maximum allowable submersion depth below the water level is 9 meters. The pumped water must be free from abrasive particles. For safety reasons, it is recommended to hang the pump on stainless steel or nylon ropes using specially designed ears on the pump's upper part. It is recommended to install an additional check valve after the pump in the discharge pipe.

Recommendation:

1. The pump's service life significantly increases if the cut-off pressure is set not higher than 3 bars.
2. It is recommended to install fuses that are 20% larger than the motor's rated current.
