Product Description: Seal-Less Design: 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.
Multiple Connection Types: 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.
Long Life: 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.
Readily Compliant with International Standards: 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.
Flow Adjustment Feature and Built-In Drive Technology: 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.
High Temperature Environments: 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.
