About the Features, Applications of Diaphragm Vacuum Pump

Diaphragm vacuum pump( Standard Diaphragm Vacuum Pumps and Anti-Corrosion Diaphragm Vacuum Pumps) is to provides an ideal vacuum environment for many chemical experiments. Its working principle is as: an elastic diaphragm mounted on an eccentric crankshaft reciprocates up and down under the drive of a motor, and the cavity is deformed to realize the pumping and discharging of the medium. Diaphragm pumps do not need oil at all during the transfer, evacuation, and compression processes, and truly achieve pollution-free transmission.

Hawach scientific diaphragm vacuum pump advanced design, high efficiency, long service life. Widely used in medical and pharmaceutical product analysis, fine chemical industry, biochemical pharmacy, food inspection, and other fields, can be used with filter device or multi-filter, simple operation, safe and reliable, meet the needs of the laboratory.

Features of Diaphragm Vacuum Pump

1. HAWACH diaphragm vacuum pump features reasonable transmission design, self-cooling exhaust system, long-term continuous operation, with small size and light weight, which is easy to move, easy to repair and maintain, saving laboratory space.
2. It does not need to use any medium when working, so it saves water and is environmentally friendly. It has extremely high efficiency and long service life.
3. There is no need for any working medium, and there is no friction at the working part.
4. The vacuum is stable and easy to control the vacuum degree, which can be adjusted according to the needs of the experiment.
5. The air inlet is a separating bottle, which can prevent solid particles and liquid water from entering the pump body.
6. This product does not need any medium (no oil), does not produce pollution, and guarantees the air to be clean.
7. New technologies and processes are adopted in the production process. Make it work smoothly, thus ensuring the ideal pressure and vacuum degree.
8. The mechanical operation system adopts international famous brand imported bearing, making the whole machine run smoothly with a small vibration.
9. The power system is designed for high-grade motor, and the fan cooling and exhaust configuration with high rotation speed enables the machine to work continuously for 24 hours. Meanwhile, the motor is equipped with an overheating and overload protection system to ensure the safe and high-energy working efficiency.
10. Air design and advanced structural innovation have obtained two national patents.

Installation Notes

Diaphragm vacuum pumps have certain requirements during the installation process, as follows:
1. Choose a place with solid ground to install the diaphragm vacuum pumps, and save space in advance for inspection and maintenance.
2. The foundation should be kept level under the base of the diaphragm vacuum pump. The four corners of the base should be filled with shock-absorbing rubber or installed with bolts to ensure smooth operation of the diaphragm vacuum pump and low vibration.
3. The connecting pipe between the diaphragm vacuum pump and the system should be sealed and reliable. For small diaphragm vacuum pumps, metal pipelines can be used to connect the sealing gaskets with oil-resistant rubber. Use vacuum hoses for connection, if it is the small diaphragm vacuum pump.
4. For diaphragm vacuum pumps with cooling water, connect the cooling water as required.
5. For example, when a solenoid valve is installed at the diaphragm vacuum pump port, the valve and the diaphragm vacuum pump should act at the same time.
6. When the exhaust gas of the diaphragm vacuum pump affects the working environment, a pipe can be installed at the exhaust port to lead away or an oil mist filter can be installed.
When using a diaphragm vacuum pump, pay attention to the changes of the instrument, and pay attention to maintenance after the time of use, to prevent factors that affect the measurement results in the next use.
