Description of NOWA 4SKM 1000-6154rc Submersible Vortex Well Pump

The NOWA 4SKM 1000-6154rc submersible vortex well pump is designed for lifting and supplying clean cold water from wells, boreholes, cisterns, and other deep sources that meet the technical conditions for pump placement and mounting.

The NOWA 4SKM 1000-6154rc submersible vortex well pump belongs to the class of submersible monoblock rotary pumps with a vertical shaft arrangement and an open-type impeller. The motor is located in the lower part of the pump, and the upper flange has a threaded outlet for connecting the pipeline and a check valve. The pump is suspended using a flexible cable attached to special eyelets.

The pump can be used independently or as part of adaptive, automatic, and non-automatic pumping stations for:

• organizing autonomous water supply;
• use in irrigation systems;
• draining clean water (reducing groundwater levels, irrigation).

The pump is not intended for pumping mineral and sea water, chemically active, aggressive, and flammable liquids and solutions. The water pumped by the pump must not contain abrasive particles or long-fiber inclusions.

Operating conditions:

• the size of abrasive particles must not exceed 0.05 mm;
• the total content of mechanical impurities in the water must not exceed 20 g/m³;
• the water should not have a high degree of mineralization — no more than 1500 g/m³ in dry residue;
• the acidity index (pH) must be in the range of 6.5 to 9.5;
• chloride content — no more than 400 g/m³, hydrogen sulfide — no more than 1.5 g/m³;
• operating temperature range of pumped water — from +1 °С to +35 °С;
• maximum number of motor starts per hour — no more than 20;
• minimum well diameter is 100 mm;
• maximum immersion depth is 70 m.
