Founded in 1995, China Dongda Power Industry Co., Ltd. is one of the few pump motor manufacturer and distributor in China that has patents on the generator, motor, power supply, engine, alternator, diesel and gearmotor design, supply and sale. Our custom pump motors has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS and we have won EPA 2005 Motor Year Certification. Our 30 QC staff carefully performs inspections at every stage of production, from the time we receive raw materials to packaging. Noise, power, and stability are tested to ensure that our engines can endure 580 hours of constant use. We also can design and deliver OEM/ODM samples in one month.

115/230 volts 7.5/15 amps 60hz. Automatic Overload Protection - Service Factor 1.0. Non-Reversible - CCW Rotation facing the shaft. C-Face Mount, Round Body-no base. 5/8" diameter threaded shaft
Swimming pool pump motor. Commonly found on inground pool pumps such as Hayward Super Pump, Maxflo, Super II and many other pumps requiring a 56J frame motor. AO Smith motors are found on most swimming pool pumps. Standard 1081 pump duty motor. Stainless steel shaft. Sealed ball bearings. Motor has 4 threaded bolt holes on face for mounting the pump to the motor. Bolt holes are 5 7/8" on center measured across the shaft. Wiring diagram on motor name plate. 1 year warranty. The design solution resulted in a pump with extremely high power density (horsepower to weight ratio), at less than half of the industry standard weight for a comparable hydraulic pump.

These pumps and motors have a place of their own in the industrial pump market. Current hydraulics suffer from critical problems: Rotating piston group. Inefficient valving. Hydraulic whine. Heavy housings. Existing pumps need to be large and heavy in order to deliver the desired power. The size and weight prove detrimental in automotive design, as valuable space and weight are eaten up by the hardware. Torvec innovation led to the design of their own Hydraulic Pump. Torvec has eliminated the rotating piston group (the cylinders are stationary), making the pump tremendously powerful and easy to manufacture.Torvec's patented valving has been integrated to increase efficiency and reduce noise (hydraulic whine). The challenge was to deliver the necessary power while reducing the size and weight of the pump, using parts that can be manufactured at high volume and low cost. For example, most 12 cubic inch displacement pumps range from 200 lbs - 270 lbs, while Torvec's 12 cubic inch displacement pump weighs in at approximately 75 lbs.
