1.This kind of pump has dual function that can be used for liquid or gas sampling.It is a self-priming pump. (When turned on ,the pump starts to do the liquid sampling, no extra water is needed at the beginning.) It also allows dry running.(When the liquid runs out or without liquid ,the pump can run smoothly without any damage)
2.It is equipped with brushless DC motor, durable and low interference. It can run continuously around the clock without interfering with the surrounding electronic components or polluting power source. Stable performance and high reliability. Maintenance-free . Damp gas as the medium is acceptable. No pollution during the gas transmitted as it is oilless operation. Corrosive gas is allowed to be input(The material for the parts which come in contact with gas : Glass fiber reinforced nylon ,EPDM rubber)
3.It facilitates the adjustment of output flow of the pump. The flow rate can be changed by freely adjusting the revolving speed of the motor through electrical control, which makes it easier to achieve automatic control, noise reduction, shock absorption, and energy saving. Compared to the way to change flow rate via mechanic valve, it is more suitable for automatic control, more precise and cheaper. The series is on the PWM(Pulse Width Modulation)circuit to change the revolving speed of motor and thus alter the flow rate.
4.There are feedback signals about the revolving speed of motor, which indicate the operational condition and output flow alteration of the pump and thus facilitate the intelligent control. Perfect self-protective function. It has functions of overload protection. (This function do not apply to Economical version)
5.It is free of maintenance and is non-lubricated. The pump is oil-less and will not pollute the gas transmitted. Extract of damp gas is allowed.
6.Low noise.It can be installed in any direction, for example, being installed horizontally, vertically, or in a slope, and work properly.
