Micro brushless DC Variable Speed Vacuum Liquid Pump
Shipped in 3 days after payment
WKY series 12V Micro brushless DC 24V Negative pressure Variable Speed Vacuum Liquid Pump
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,silicon rubber)
3.It can be mounted in any plane.such as horizontal plane, vertical plane,slope.Perfect self-protective function. It has functions of overheating protection and overload protection.(this function do not apply to Economical version) The pump applies to wide fields,especially in gas (or liquid) analyzer,industrial instruments etc.
As the vacuum pump
As the liquid pump
Remark : customized is available
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.
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
*Testing of Water Suction and Discharge Height
1.All the connective hose is flexible rubber hose(Inner diameter approximately 5mm)
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.
height H1 (m)
Flow rate at Max.suction height
Flow rate at Max. drainage height
Remark : To test the H1 ,The length for drain-hose is <100mm . To test the H2 ,The length for suction-hose is <100mm.
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.Customization is available.
4.Weight: approximately 310 g.
5.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.
The pump shall not be exposed to direct sun light. It shall work in clean and non-corrosive environment. Ambient temperature: Economical version: 0-40 ℃ (No condensation) Simplified version & standard version:0-50 ℃ (No condensation) Relative humidity: ≤ 90 %
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:
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.
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, otherwise, it shall be normal-temperature medium type.
Temperature range allowed for gas suction
Normal-temperature medium type
Solid particles such as ice particles are forbidden to be contained in the gas suction.
High-temperature medium type
Warning:No hot plugging!No connect or disconnect the motor leading wire when the power is on. Forbid to reverse the positive and negative pole ,otherwise the motor will be damaged!
Power positive pole +12V(±10%); +24V(±5%)
No reverse the positive and negative pole, it will not damage the motor.t
power negative pole
*Motor electrical schematic diagram and peripheral circuit:
*GA7.8 Filter *Silicone tube
Note: A medium size filter and a 10cm silicone tube will be included in the package for each pump.
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.
