Purpose: Submersible borehole pumps 4" DAB S4 designed specifically for individual and collective systems of water supply, and irrigation systems. For wells with a diameter of 4" or more.
Operating range: performance - from 0.24 to 24 m3/h, head up to 320 m. water column.
Maximum working pressure: maximum immersion depth 20 m.
The pumped liquid. Composition: clean, free of solids and mineral oils, not viscous, chemically neutral, characteristics similar to water. Maximum sand content in the water -120 g/m3. Temperature: 0°C to +40°C.
The basic materials. Impellers, diffusers, valve - technopolymer; cover, hydraulic parts, engine cover, shaft, sleeve, protective cable cover, base hydraulic parts of the engine are of stainless steel.
Features. Multi-stage downhole pump. All single-phase models require retrofitting device Control Box, an embedded capacitor and overload protection with manual reset. Additionally, single-phase models can be supplied (order separately) Control Box HS for increasing the starting torque. For three phase models require external overload protection.
Installation. The motor shaft is in a vertical or horizontal position. In the case of horizontal position of the shaft must comply with the load-bearings and arrange a flow of fluid for cooling the engine.
Package contents: pump Assembly.
Standard power supply: 1x230 V, 3x400 V.
Degree of protection: IP 68.
