How do the SAER 10″ lines differ?
NR250 is designed for the highest head among SAER borehole pumps, up to 955 m. It has an integrated check valve and a steel outer jacket. The line is used to feed autoclaves and storage tanks, in washing systems, for irrigation and underground extraction.
S252-253 delivers the highest flow in the series, up to 400 m³/h. Depending on the size, the pump can be coupled with 8″, 10″ or 12″ motors. Its wear parts and investment-cast components are designed for harsh conditions, and the Super Duplex version for marine environments.
VS10 is the high-efficiency line for pumping stations, the marine sector, offshore, mining and irrigation. The Super Duplex version is intended for brackish water and sea water.
Which versions and accessories are available?
- horizontal installation on request;
- PE+PA wound motor for variable frequency drive operation or hot water;
- FPM seals for stainless steel versions (S252-253, VS10);
- cooling jacket, cables, control panels, PT100 sensors.
Where are SAER 10″ submersible pumps used?
Глибокі водозабори комунальних систем і підприємств, насосні станції, зрошувальні системи, водовідлив у шахтах і кар'єрах, морський сектор, допоміжні системи офшорних платформ.
How to select a SAER 10″ pump?
We need the flow and head at the duty point, the dynamic level, casing inner diameter, water composition and temperature, and the motor starting method. For heads above 390 m we consider NR250; for flows above 210 m³/h, S252-253 or VS10.
Steiner Ukraine selects the line, number of stages and motor, supplies the pump and spare parts and carries out installation and service. Other borehole series are listed under submersible pumps.
