Screw borehole pump 4QGO2-120-1.5, 120 m, 1.5 kW

Description

Screw borehole pump. The 4QGO2-120-1.5 screw borehole pump (120 m, 1.5 kW) is designed for pumping clean water from boreholes and reservoirs. Maximum head is 120 metres, flow rate reaches 2 m3/h, and power output is 1.5 kW. The pump is made of stainless steel, fitted with a screw mechanism, and has an outlet diameter of 25 mm.

Specifications

Pump type

Screw (the working element is a steel screw in a rubber sleeve).

Power

1.5 kW (a high figure for residential models).

Maximum head

Up to 120 metres.

Flow rate

Nominally about 2 m3/h (33-40 L/min).

Housing diameter

4 inches (about 100-102 mm).

Advantages of this model

High head

Ideal for deep boreholes or when water needs to be pumped a long horizontal distance.

Sand resistance

Screw pumps handle small amounts of sand better than centrifugal pumps (though they still dislike heavy contamination).

Serviceability

If worn, the screw pair (screw + coupling) is fairly easy and inexpensive to replace.

Stability

Delivers an even water flow without strong pulsations.

Who is it for? This pump is worth choosing if you have a deep water table (50 metres or lower) or if you need to set up irrigation and water supply for a house located far from the borehole.

Important note

Because of its high power (1.5 kW), make sure your wiring and automation (pressure switch) are rated for this starting current.
