Direct drive pumps A compact centrifugal pump with canned motor further covers a higher flow rate. RD-40 (High head type) Max.discharge capacity: 25 L/min Max. head: 15 m Max.discharge capacity: 70 L/min Max. head: 8 m Our RD series design features small canned motor centrifugal pumps powered by brushless DC motors. They are designed to be cool, quiet, compact and lightweight. A variety of features, including a seal-less design to prevent leakage, enables the pumps to meet a full spectrum of user needs, with emphasis on ease of installa�on, opera�on and maintenance. The high head type and the high flow type are new addi�ons to the range. Choose the most suitable model from a wide selec�on. Compact and lightweight with a seal-less structure The pumps with a canned motor offer compactness and light weight. Compared with conven�onal magne�c drive pumps, they require minimal space for installa�on. Select the best connec�on for your plumbing system from tube, R pipe and NPT pipe. Seal-less structure eliminates wear leakage and other problems involved with seal replacement. Safety voltage Built-in drive circuit The RD series power voltage is classified as safety voltage (50V or less), which allow the user to easily comply with international standards such as UL, CSA, CE and GS. A drive circuit is fi�ed as standard inside the pump. Connect power to the pump and provide an external signal to start opera�on. The pump can handle hot liquids up to 80˚C. The DC power system overcomes installa�on limits for voltage and frequency of each area. Long life design Flow rate adjustment Use of a DC brushless motor eliminates concerns over brush abrasion, ensuring a service life comparable to an AC motor. Flow rate can be adjusted by means of an external signal of 1-5VDC.
