SAER – Submersible pumps (series 4)
SAER Elettropompe 4″ is a powerful series of 4-inch submersible pumps designed for lifting clean water from wells, reservoirs, and open aquifers. The high quality of Italian manufacturing ensures reliable operation in water supply, irrigation, and technical water systems.
Basic models
4N — basic version made of high-quality AISI 304 stainless steel for clean water.
4P — version with polymer impellers, optimized for domestic and agricultural water supply systems.
4R — reinforced version with hydraulic components made of AISI 316 for more demanding operating conditions.
Technical characteristics
Typical series parameters: flow rate — up to ≈21 m³/h, head — up to ≈340 m, power — from 0.37 to 7.5 kW. Maximum liquid temperature — +35 °C, allowable sand content — up to 150 g/m³. The casing and shaft are made of stainless steel, while the impellers are either polymer or metal, depending on the model.
Advantages
Compactness and versatility — ideal for 4″ (≈104 mm) wells and reservoirs.
High head — ensures water supply over long distances or to elevated points.
Stainless materials — ensure long service life even in hard water conditions.
Energy-efficient design — optimized hydraulics reduce electricity consumption.
Italian manufacturing quality — control at all stages from design to testing.
Application
SAER 4″ pumps are used for water supply in private and commercial facilities, water extraction from wells, pressure boosting in reservoir systems, as well as in agriculture and irrigation.
Company Steiner Ukraine supplies SAER 4″ submersible pumps from the official production line in Italy, providing technical selection, warranty, and service support throughout Ukraine.
