Compact centrifugal pumps of the series NUB from the company EDUR They are universal in application and are used for pumping liquids of low density in many industry directions. For this line, there are many settings for sealing the drive part (mechanical seal reinforcement, magnetic coupling), for working with slightly polluted streams, for special operating conditions. Cast iron, bronze and stainless steel are used as body and impeller materials in various combinations depending on the selected version. The suction nozzle is located coaxially to the motor unit, falling radially upwards.
In general, these are very reliable and easy-to-maintain pumps, with an optimized design for energy-efficient operation and designed for a long service life. Three-phase AC electric motors with a high class of protection against dust and moisture are used as standard for the drive.
Pumping liquids: water, solutions, oils.
Limitations: no abrasive particles, contact with chemically aggressive agents.
Areas of application: water purification, cooling systems, marine applications, plastic industry, mechanical engineering and other industries, technological processes.
