long lifetime Brushless DC 5~12M water lifting pump

This is a brushless DC motor-driven centrifugal pumps, use special design closed impeller, main features: high water head, moderate flow rate, long life (use fine ceramic bearing), continues work, low noise, stable performance.

√ Pump chamber and the motor is absolutely isolated, magnetic drive technology can be guaranteed no leak for ever, completely avoid the presence of traditional DC motor pumps' liquid leakage. Effectively raising the pump life and performance. If the mining epoxy resin package, you can completely and totally waterproof diving use.

√ Brushless motor circuit design optimization using a large movement of low-temperature, stable performance, long life. Closed impeller simple structure, with less water loss, pump output high efficiency, can effectively enhance higher water head.

√ Impeller/rotor shaft with ceramic materials, enhance the wear resistance, high accuracy, precision with resistance to shock, to extend the life of the pump. Bearing sleeve with graphite self-lubricating properties, reduce noise at work. Low noise down to *5dB, smaller consumption pump even down to *0 decibels, almost silent operation.

√ Pump chamber seal can withstand 5 bar pressure without leakage. Each pump in the production line have to go through stress tests, which can effectively prevent the leakage of product defects.

√ Pump uses high-strength engineering plastics, PPS PPE, PA*6, etc., can be used for hot water circulation, strong endurable capacity, resistance to weak acid corrosion. Can be recycled with a small impurity of the liquid, do not plug the pump chamber.

Brushess *2V DC water pumps work Note:

1. Power to DC Power Supply, reverse polarity is strictly prohibited, generally red positive power supply, black to negative
2. pumps in addition to immersible work can be identified, the rest can not be immersed in water, or they will cause a short circuit burned.
3. pumps is prohibited by the strong shock, fall from a height on the ground and other external damage.
4. pumps can not take strong acid and other corrosive liquids and granular solids with a tiny hard. Can not cycle more thick viscosity liquids, such as oil, high concentrations of oil and other fluids vast.
5. pumps was not long-time stall, causing the motor burned.
6. pumps can not withstand high voltage shock.

Other value-added services:

(1) Product is one year quality guarantee
(2) Each pump using separate packages, effectively prevent collision damage.

Customers how to choose the pump
1. first determine the voltage, current,water head and flow, diameter size, pump water head is generally the subject of the water does not flow when pumped up to the static head, if a customer requires pumping the water to a certain height and then to maintain a certain water flow, select the desired water head must be higher than the specified pumping height. This specific by the supplier according to the actual conditions. Can refer to lift flow graph.
2. to determine the dimension and form (threaded interface, inlet and outlet orientation, aperture size, etc.)
3. to determine the job requirements (temperature, medium, work time and frequency)
4. to determine the functional requirements (time control, pressure control, flow control, speed, etc.)
