Water Pumps

Process and Chemical Pumps

ANDRITZ develops and manufactures standard and customized centrifugal pumps such as end-suction, split case, high-pressure and numerous other pumps for a wide range of different applications and industries.

• Highest energy efficiencies
• Lower life-cycle-costs
• High-standard pump engineering

ANDRITZ develops and manufactures submersible motors for various fields of application in water supply, mining and offshore. Equipped with a special cooling technology (MCT) and an interior permanent motor technology (IPM), ANDRITZ submersible motors achieve impressive performance values, efficiencies, and cost savings.

Their rewindable winding makes ANDRITZ submersible motors from the SM series the ideal drivers for submersible deep well pumps, bottom intake pumps, seawater lift pumps, and for subsea machinery. Thus, they can be used for water supply and in the offshore as well as the mining industry. They are designed as water- filled and water-cooled three-phase asynchronous motors with squirrel-cage rotors with a mechanical shaft seal. Depending on the field of operation, ANDRITZ submersible motors from the SM series can be made of cast iron, bronze or stainless steel and can be installed vertically and horizontally.

ANDRITZ SM motor series - high-voltage motors:

Design: water-filled and cooled three-phase asynchronous

Power: up to 5,000 KW

Voltage: up to 14,000 volts

Temperature: up to 75° C

Speed: up to 3,600 rpm

Product benefits:

Reduced investment and energy costs

Drinking water as the cooling medium

Suitability for media temperatures up to 75 °C

Maximum operational reliability

Extremely long service life

Enormous increase in efficiency up to over 100% for the same size

A broad range of application reduces storage and logistics costs

Extremely high efficiencies up to the part-load operational range guarantee lowest energy costs

High efficiencies and an excellent power factor go along with lower power consumption and thus enable the use of smaller cable cross-sections

Flexible adaptation of pump performance to the duty point via frequency converter without losses

By operating in backward mode, the pump becomes a mini-turbine that can generate a very healthy ROI by recovering and generating electrical power. ANDRITZ pump- turbines are an economical alternative, compared to the cost of buying and operating a conventional turbine. They operate, for example, as recovery turbines in pulp and paper mills, in small hydropower plants, and supply energy to mountain refuges and forest lodges. Thereby, the transport various media ranging from drinking water, residual and waste water as well as pulp suspensions.

The pump-turbine for energy recovery is best applied in situations where high- pressure is needed in one part of the process, but no longer required afterwards. Typically in these installations, the pressure is reduced with a relief valve and the energy stored in the high-pressure fluid is lost. The ANDRITZ pump-turbine efficiently recovers this “lost” energy and generates low-cost power from it.
