RD series

Product catalog summary

Overview
The RD series consists of small canned motor centrifugal pumps powered by brushless DC motors. These pumps are designed to be cool, quiet, compact, and lightweight, making them easy to install and maintain. They feature a seal-less design to prevent leakage and are suitable for machine-installing applications.

Specifications
- Operating voltage: 14 V to 24 V (excluding RD-30TV24-HV)
- Optional 500 mm cable available (excluding RD-05H)
- RD-30TV24-HV can be controlled by 1-5V external control signals
- Models include RD-05, RD-05H, RD-12, RD-12Z, RD-20, RD-30, and RD-30TV24-HV
- Maximum capacity and head vary by model, with power consumption ranging from 9.6 W to 77 W

Construction and Materials
The pumps are constructed with materials such as PPE, GFRPP, PTFE with filler, alumina ceramic, FKM, and EPDM. The design includes components like casing, rear casing, impeller, spindle, thrust ring, O-ring, and bearing.

Features
- Compact and lightweight with a seal-less structure
- Long life due to the use of a DC brushless motor
- Compliance with international standards (UL, CSA, CE, GS)
- Easy flow adjustment by changing power supply voltage
- Built-in drive circuit for simple operation

Applications
The RD series pumps are used in various applications including medical care (biochemical analysis, cooling devices), physical/chemical analysis (thermostatic devices, demineralizers), automatic vending machines, photography, semiconductors, surface treatment, solar power systems, and electric cars.

Operating Principle
The pumps operate by directly driving the rotor magnet incorporating an impeller. The pump chamber is completely sealed from the exterior by a casing, eliminating the need for a shaft seal.

Performance and Adjustments
Performance curves are based on operation with a 5V external control signal. The pumps allow for easy flow adjustment and have standardized models that use the same DC voltage across different regions.
