NRD/RD

Product catalog summary

Overview: The IWAKI NRD series consists of small canned motor centrifugal pumps powered by brushless DC motors. These pumps are compact, lightweight, and feature a seal-less design to prevent leakage. They are suitable for high-temperature liquids and can operate in high ambient temperatures.

Specifications: The NRD series includes models NRD-05, NRD-08, NRD-12, NRD-20, and NRD-30. They support a power voltage of DC 24V and have a flow adjustment feature using an external input signal (DC 1 to 5V). The pumps can handle liquids with temperatures from 0°C to 80°C and operate in ambient temperatures from 0°C to 50°C.

Design and Features: The pumps have a seal-less design with a resin-encapsulated motor, reducing space requirements and preventing leakage. They offer multiple connection types: Hose Barb, NPT Thread, or R Thread. The brushless DC motor ensures long life by eliminating failures due to brush wear.

Compliance and Standards: The NRD series complies with international standards such as UL, CSA, CE, and GS due to its classification as a safety voltage product (50V or less). The DC power supply is not region-specific, allowing for global usage.

Applications: These pumps are used in various applications, including fuel cells, medical equipment, vending machines, semiconductors, solar power systems, and electric cars.

Materials: Key materials include GFRPPE for the front and rear casing, alumina ceramic for the thrust ring and spindle, PTFE with filler for the bearing, and FKM or EPDM for the O-ring.

Performance: The performance curves indicate maximum capacities and heads for each model, with noise levels measured at up to 45 dB. The pumps are designed for fluids with a viscosity limit of up to 1.0 mPa·s.

Dimensions: The document provides detailed dimensions for each model and connection type, highlighting the compact nature of the pumps.

Safety and Export: Users are advised to read the instruction manual carefully for safe use. The products may require an export license due to international export control regulations.
