  • Performance
    The company's multi-stage stainless submersible pumps and asynchronous motors are produced according to the national standard GB/T 2816-2002、GB/T 2818-2002.Meanwhile, the company introduces from abroad advanced technology and floating type impeller structure. When motor works,there is no axial pressure, in this case, it extends the using life of motors.There are two kinds of motors:oil-filled type motor and dry-type motor. Oil-filled type motor has good cooling function and lubricity, and dry-type motor won't cause any pollution to water.The pump body and shaft are both made of stainless steel material which improves theirs anti-corrosion. The capacitors of single phase motor are also two kinds: build-in capacitor and external capacitor with a switch box.

    The motor and pump body are standalone respetively and interchangeably,and we can combine the two parts into a whole structure through coupler.Pump uses high quality mechanical seal with reliable performanceand easy maintenance.Motor owns the functions of sand-proof,wear-resistance,less power loss and save energy.Pump has characteristics of small external diameter, high flow, high head, high efficiency in drawing water as well as beautiful appearance, good quality, long using life (many times than common pump).The connecting pieces are three types according to customers' need: cast rion, copper, stainless steel; and the cable of motor is 3M as usual (according to the customers' requirements).The technical data of pumps in this book are equiped with 380V/50HZ, 220V/50HZ,certainly, we can produce the series of 220V/60HZ,110V/50HZ,110V/60HZ,380V/50HZ if required.

    Applicable scope
    Pumps are suitable for deep well water and high-rise building water in the following fields:mine industries, manufactories, agriculture, construction industry,aquaculture,food beverage industry and household,especially for drawing water from small-bore deep wells.
