6V/9V/12V/24V DC PWM adjustable speed brushless diaphragm pump
A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum.
Performance measures
Pumping speed refers to the volume flow rate of a pump at its inlet, often measured in volume per unit of time. Momentum transfer and entrapment pumps are more effective on some gases than others, so the pumping rate can be different for each of the gases being pumped, and the average volume flow rate of the pump will vary depending on the chemical composition of the gases remaining in the chamber.
Throughput refers to the pumping speed multiplied by the gas pressure at the inlet, and is measured in units of pressure·volume/unit time. At a constant temperature, throughput is proportional to the number of molecules being pumped per unit time, and therefore to the mass flow rate of the pump. When discussing a leak in the system or backstreaming through the pump, throughput refers to the volume leak rate multiplied by the pressure at the vacuum side of the leak, so the leak throughput can be compared to the pump throughput.
Positive displacement and momentum transfer pumps have a constant volume flow rate (pumping speed), but as the chamber's pressure drops, this volume contains less and less mass. So although the pumping speed remains constant, the throughput and mass flow rate drop exponentially. Meanwhile, the leakage, evaporation, sublimation and backstreaming rates continue to produce a constant throughput into the system.
adjustable speed brushless pump's parameter and features
Small mechanically activated diaphragm pumps are also used as air compressors and as a source of low-grade vacuum. Compared to other compressors, these pumps are quiet, cheap and, most importantly, have no moving parts in the airstream. This allows them to be used without added lubrication in contact with the air, so the compressed air produced can be guaranteed clean.

environmental testing requirements about adjustable speed brushless pump
| Number | Item | Test conditions and requirements | Remarks |
| 1 | Steady-state heat and wet | 60%rh | High humidity can affect the electrical performance of the motor |
| 2 | Temperature Shock | The pump was placed at -20 ℃ environment ,after 1h immediately placed at + 70 ℃ ± 3 ℃ environment for 1h.This is for 1cycle. After 50 cycles was returned to room temperature.0.5h later,pumping power test is conducted. The pump should be able to work properly; fasteners should not loose , in working condition pump’s body should not be leakage when block pump’s outlet. | too high temperature affect pump’s parameters, life and electrical performance |
| 3 | High temperature test | Pump is at 70 ℃ ± 3 ℃ environment for 48h. Then take it out. After 0.5hours later, at room temperature power pump. Fastening points should be no loose. The pump can work normally. Its performance and parameters can not change. | |
| 4 | Low temperature test | For 72 hours,pump is at -20 ℃ environment. Then take it out. Power the pump and test it.( when testing the pump,pump’s body can not have ice ). Fastening points should be no loose. The pump can work normally. Its performance and parameters can not change. | In too low temperature,motor cannot be started |

Special requirements for materials about adjustable speed brushless pump
All materials comply with environmental standards.
Motors comply with EMC.
pump material is nonflammable or any fire should be fully extinguish within 30
seconds under 10 seconds of ignition test.
adjustable speed brushless pump's dimension
Unlabeled tolerance is ± 0.1mm.
Pump Size:102.4*70*40mm
Pump Weight:300g;
Outlet:OD 5mm, silicone hose suggestion:ID 3.5mm
Materials:pump body: PC/PPS, diaphragm: EPDM
Because we use imported ball bearing,the pump’s performance is stable and high.
The membrane is made by EPDM and pump's body is made by special PC/PPS which make pump well endurance and strong chemical resistance.
External PWM speed control principle
1, control board wiring diagram:
2, external use PWM speed control principle:
Description: 1, the external PWM signal by a small MOS tube or after the transistor processing, received a speed adjustment (such as above).
2, the frequency of PWM signal can be adjusted by 100HZ-1KHZ, and the change of speed regulation 0-6V can be realized by adjusting the duty ratio.. When the duty cycle is 100% (i.e., total height), the speed regulation is 0V, and the time ratio is 0 (i.e., the total low), the speed regulation is 6V, and the speed is at full speed.
Our company offers multiple component configurations allowing pump to be used for either vacuum operation, pressure operation, or alternating vacuum and pressure operations.The innovative, compact design incorporates leading edge technologies that allow it to operate harder, quieter and longer, reliable, highly efficient.
Its flow can deliver up to 3 L/min and 18L/M.
Usually our pump has 4 kinds of voltage:6V, 9V,12V and 24V .
