  ●Characteristics:

    1.Integrated speed adjustment function,flow regulation is very convent.

    2.Two speed adjustment function type,good expansible. One, use the built-in speeder .Another one, adjust the speed with the external potentiometer.

    3.The function of integrated speed indicator, according to the flash frequency of the indicator to understand the operation of the pump intuitively.

    4.Perfect self-protective function. It has functions of overheating protection and overload protection. (This function do not apply to domestic version)

    5.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 : SPS(Glass fiber reinforced nylon, EPDM rubber).

Remarks:
1.The more ★ is,the better performance of this pump shall be.
The fewer ▲ is the lower electromagnetic interference of this pump shallbe.

2.The above comparison does not mean a product is not good.
It is for customers reference only. Here by Instructions!

Tips for service life test:

1.Test condition: The service life test results based on clean & non-corrosive laboratory,
the pumps run continuously around the clock with full load. If the operation condition is
better than that of our, service life will be greatly extended.
Laboratory conditions:

Ambient temperature: 5℃-33℃, fluctuates according to the climate
Relative humidity: 50%-85%, fluctuates according to the climate

2.Instructions for Loading Test:When the inlet completely been blocked, gas outlet through
to the atmosphere without any connection.

3.Because the test is undergoing checking, the data may be updated in future without any notice.

 

 

 

Attentions:

    1.The inlet of this pump can run in heavy duty ,even completely blocked, both are proper functioning.

    2.The outlet of this pump should remain unobstructed. If not ,as the result of the blockage, the high-pressure will be caused and threat to safety. If you need large damping components for the outlet, please select the FML or FNY、FKY、FCY serials.

    3.Weight: approximately 280 g.

    4.All parameters presented in this instruction are based on the standard atmospheric pressure at 25℃, unless otherwise defined. The free flow is referred to as the flow.

 

 ●User Instructions

    1.Service Conditions

        ①The pump shall not be exposed to direct sun light. It shall work in clean and non-corrosive environment.

        ②Ambient temperature: 0℃ ~ 40 ℃ (No condensation)

        ③Relative humidity: ≤ 90%

     2. Working Medium

        ①Gas or liquid is allowed, but with solid particles are not acceptable. The materials and names for the parts which come in contact with gas as below:

 ●Operation Instruction

     1. Operation with Built-in Speed Controller

        ①Switch the "Option switch" to "Built-in control" position

        ②Connect the power line: connect the red line to the power anode and the black one to the cathode.

        ③Power on.
The pump starts to work. Meanwhile, the red power light is on, and the green light flashes. At this moment, the pump output flow can be regulated through rotating the knob in the "built-in speed control" hole with cross screwdriver. The higher flashing frequency of the green light indicates larger pump output flow, and vice versa. If the green speed-indicating light does not flash (off or constantly on), the pump is stopped.

      2. Operation with External Speed Control Potentiometer

        ①Switch the "Option switch" in "External control" position

        ②Connect the potentiometer with the "External control" connector as shown in the figure. It is required to use 47K potentiometer.

        ③Connect the power line: connect the red line to the power anode and the black one to the cathode.

        ④Power on.
The pump starts to work. Meanwhile, the red power light is on, and the green light flashes. At this moment, the pump output flow can be regulated through rotating the externally-connected potentiometer. The higher flashing frequency of the green light indicates larger pump output flow, and vice versa. If the green speed-indicating light does not flash (off or constantly on), the pump is stopped.

      3. Operation Precautions

        ①The buit-in speed knob is very precision, rotation must be very gentlely! Less than a circle of rotation.

        ②No hot plugging. Be sure to connect all the wires before power on, pull out the wiring after power off.

        ③Prohibit rotate the switch which can choose built-in or external regulation, in the operation.

        ④If reverse the negative pole and positive pole ,the motor will not be damaged ,but the pump can not able to work.
