Characteristics:

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.)

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.

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

4.Double-chamber cooperation control,small vibration,medium flow steady.

5.Maintenance-free, No pollution during the gas transmitted.(The material for the parts which come in contact with
liquid or gas: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 shall be.

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

●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 outlet completely been blocked , gas inlet through to the atmosphere without any connection. 

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

 

Tips for selection of products:

1.To be used as gas pump,both the inlet and outlet of this pump can run in heavy duty,even completely blocked,
both are proper functioning,the pump will not be damaged.

2.To be used as liquid pump,the inlet of this pump can be completely blocked,it is proper functioning.The outlet
of this pump can also be completely blocked,but the time must be short.

3.Service Conditions

The pump shall not be exposed to direct sun light. It shall work in clean and ventilation environment.
Ambient temperature:
Economical version: 0-40 ℃ (No condensation)
Simplified version :0-50 ℃ (No condensation)
Relative humidity: ≤ 90 %

4.Working medium

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

 

Part name

Part material

Remark

pump body

Glass fiber reinforced nylon

All material has certain ability of corrosion resistance, please evaluate the tolerance of the parts which come in contact with gas pumped.

 diaphragm

EPDM  rubber

valve

Medium temperature: 0~50℃

5.Weight: approximately 500 g.

6.There are three connect or for your option, please specified when ordering.If there is no remark,it'll be
considered that you order the Pagoda joint. Such as WXY131.5-24V(one-touch tube fitting), more detail please
see the drawing below.

7.Customization is available.

 

●User Instructions:

1.Service Conditions

The pump shall not be exposed to direct sun light.It shall work in clean and ventilated environment.

Ambient temperature: 
Economical version: 0-40 ℃ (No condensation) 
Simplified version :0-50 ℃ (No condensation)
Relative humidity: ≤ 90 %

According to the temperature of gas inlet,the series product can be divided into two types,
normal-temperature medium type and high-temperature medium type. Orders for high-temperature 
medium type shall be specifically marked, such as VNY6216-24V(high-temperature medium type),
otherwise, it shall be normal-temperature medium type.

Type

Temperature range allowed for gas suction

Remark

Normal-temperature medium type

0~50℃

Solid particles such as ice particles are forbidden to be contained in the gas suction.

High-temperature medium type

0~100℃

 

●Suction height Test and drainage height Test:

1.All the connective hose is flexible rubber hose(Inner diameter approximately 6mm)

2.The liquid suction is clean water.

3.The definition for Max. suction height H1 and max. drainage height H2 as follow:

4.The data may be updated in future without any notice.

Drawing unit: mm

 

Wiring instructions:

 

1.Red power line connect the power positive pole ,black power line connect the power negative pole.(No reverse
the positive and negative pole,it will not be damaged but the pump do not run)

2.The use of power:


1.This series of pumps are the biggest starting current is 2.5 A, It lasts less than 20 millisecond.

2.When the motor starting current is in a static state, the maximum current that is generated by the rated voltage
is the basic parameter of the motor.

3.When the motor begin running,it will connect other auxiliary circuit at the same time,such as speed governing,
control... And so on, it will generate additional surge current superimposed on the motor starting current, so the
starting current will increase and more.

●Fittings
After working for a period of time, the dust contained in the gas or liquid will accumulate in the pump chamber,
and gas tightness of the pump may be damaged, and slow down the flow rate and degree of vacuum, so a filter is
needed at the gas inlet.

Silicone tube:

① One-touch tube fitting:The band of silicone tube must be SMC (Size of silicone tube:ID:6mm, OD:8mm.),otherwise
it will lead to poor sealing of joint,the tube can not normally plug,it will cause the damage of joint,etc.30mm
silicone tube is free,if you need more,please purchase by yourself.

②Pagoda joint: Size of silicone tube :ID:6mm, OD:10mm

 

●Warming:

1.To be used as liquid pump, both inlet and outlet can be completely blocked,but the outlet blocked for a while.

2.No foreign matter should keeping in the nozzle, or the micro pump may be damaged.

3.The product is not intrinsically safe.It is not recommended to be used in inflammable and explosive environment.

4.When the air pumped is hazardous,users must reseal the pump for the sake of safety.

5.Matching pipeline components and containers,must have sufficient strength,to ensure personal safety.
