●Characteristics:

1.Our company has two brands to meet different requirement of clients,"Tianying" and "Cheehie".The "Tianying"
is economical product, while the "Cheehie "is high-grade products which with excellent performance in the service
life, electromagnetic interference suppresion, low noise (especially after prolonged use) etc. But WAT series enjoy
a good reputation as brush motor pump in same industry.

2.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)

3.It can run continuously around the clock. 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. It can be mounted in
any plane.such as horizontal plane, vertical plane, slope.Corrosive gas is allowed to be input.The material for the
parts which come in contact with gas(or liquid) : Glass fiber reinforced nylon, EPDM(rubber)

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:
Make the service life test separately with two kinds of loaded, take the minimum value. Test 1 , input the
liquid continually ; Test 2 ,completely block the inlet, gas outlet through to the atmosphere without any
connection and continually do the gas suction.

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

 

●Attentions:

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.

2.To be used as liquid pump, the inlet of this pump can run in heavy-duty ,even completely
blocked. The outlet should remain unobstructed.

3.Electromagnetic interference : If the system is equipped with a precision circuit or precision
circuit around the pump ,these brush-motor pumps may cause the electromagnetic interference problems,
so the products with brushless motor are highly recommended.

4.Customization is available.

5.Weight: approximately 350 g.

6.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
The pump shall not be exposed to direct sun light.It shall work in clean and non-corrosive environment.
Ambient temperature: 0-40 ℃ (No condensation)
Relative humidity: ≤ 90 %

2.Working medium
Gas or liquid 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

 Optional Accessories

Filter Silicone tube(Note: inner diameter is about 5mm, and outer diameter is about 9mm.)

Note: A medium size filter and a 10cm silicone tube will be included in the package for each
pump.

 

  Attentions

     1.No foreign matter should keeping in the nozzle, the outlet of this pump should remain unobstructed, or the micro pump may be damaged.

     2.The product has not explosive-proof performance. No using in inflammable and explosive environment.

     3.When the gas (or liquid) input is hazardous, users must re-seal the pump for the sake of safety!

     4.All gas circuit elements such as gas tank must be provided with enough strength for the sake of safety.
