Model NRD series -Direct Drive Pumps
The pumps are equipped with a small, lightweight canned motor encapsulated in resin. This construction requires less space than magnet pumps, while the seal-less design prevents liquid leakage.
The 50V or less supply voltage is classified as compliant with international standards such as UL, CSA, CE, and GS. The DC power supply does not have a region-specific voltage or frequency, allowing for unified usage.
There are three different port connection options available, Hose Barb, NPT Thread or R Thread. Select the option that best fits your location and installation.
An external input signal (DC 1 to 5V) can be used to vary the flow rate. The NRD series models are also equipped with a built-in motor drive circuit. With this circuit, the power can be connected to variable external input to operate the pump.
A Brushless DC motor is employed as the pump drive. This motor design eliminates pump/motor failures due to brush wear, ensuring a service life equal to AC motors.
The pump can be installed in an environment with an ambient temperature of up to 50°C. It can also pump fluids as warm as 80°C.
