Features of NRD series

Seal-Less Design

The canned motor design offers the most compact package available. This construction requires less space than magnet pumps, while the seal-less design prevents liquid leakage.

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.

Flow Adjustment Feature and Built-in Drive Technology

An external input signal (1 – 5 VDC or 400 Hz ±10% of PWM, Duty 0 – 100% Note1) 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.

Note1: NRD-08Z-P4//70/70X/100/100X/100H only. Connect the PWM control signal with an open collector (drain).

Multiple Connection Types

There are four different port connection options available, Tube (Hose barb type), NPT Thread, R Thread or G Thread Note2. Select the option that best fits your location and installation.

Note2: NRD-40/40X/70/70X/100/100X/100H only.

Readily Compliant with Global Safety Standards

The NRD series power voltage is classified as safety voltage (50 V or less), which allows the user to easily comply with global safety standards such as UL, CSA and CE. The DC power supply does not have a region-specific voltage or frequency, allowing for unified usage.

High Temperature Environments

The pump can be installed in an environment with an ambient temperature of up to 50°C (08Z: 40°C). It can also pump fluids as warm as 80°C (08Z: 50°C, 100H: 70°C).

Operating Principle

Canned motor centrifugal pumps directly drive the rotor magnet that is coupled to the impeller.
The pump chamber is completely sealed from the exterior by a static o-ring. The impeller is driven by a rotating magnetic field that doesn’t require a shaft seal.
In addition, these products have a simpler and more compact structure than pumps which have external drive magnets.
