Purpose: Borehole pumps 4" DAB CS4 designed specifically for individual and collective systems of water supply. For wells with a diameter of 4" or more.
Operating range: performance - from 0.24 to 6 m3/h head up to 230 m. the 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, return valve and the base of the hydraulic part in technopolymer; cover hydraulics, engine enclosures, shafts, coupling, motor base and cover cable in stainless steel.
Features. Multi-stage downhole pump. All single phase models are equipped with a 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.
