GM-series oil-free diaphragm vacuum pump is made of aluminum alloy die-casting and anti-corrosion spray spray to meet the requirements of various working environments.
It is mainly used in the fields of pharmaceutical product analysis, fine chemical industry, biochemical pharmacy, food inspection, criminal investigation analysis, etc. It is a product of precision chromatography instruments and one of the necessary equipment for laboratories.
The oil-free diaphragm vacuum pump is advanced in design, high in work efficiency and long in service life. It is a new generation of high-tech integrated products.
There are two types of diaphragm oil-free vacuum pumps: anti-corrosion + common models
Anti-corrosion products (orange): The anti-corrosion products are treated with Teflon surface and are resistant to chemical corrosion.
Ordinary (blue): Do not touch the suction filter with chemically corrosive substances, otherwise the service life of the machine will be greatly reduced.
Different GM models have different vacuum pump numbers, pumping speed, maximum vacuum, etc., as shown in the table below.
Oil-free work:Gas exchange chamber with built-in filter material
No pollutionensuring the purity of the air
Great details!
Vent
Keep the air outlet open and do not cover.
Pure copper interface
Rugged and resistant to corrosion.
Pressure gauge (PSI)
Real-time observation of pressure values.
Pressure regulating valve
The vacuum pressure can be controlled steadily according to the needs of the experiment.
We also provide 220V products. If you need to purchase, please tell us in time to change the voltage type after ordering. Otherwise we will send the 110V type by default.
[Single head / double head]
Single head / double head refers to the single pump head / double pump head, refers to the number of vacuum pumps contained inside the machine, regardless of the interface on the appearance of the machine. We can look at the number of round protrusions on the top of the machine to determine the number of pumps.
The double pump head has a faster pumping speed than the single pump head or a higher vacuum degree that can be achieved.
[Pressure type and interface]
Positive and negative pressure dual-purpose machines generally have two interfaces for pumping and blowing;
Negative-pressure machines can only pump air, with only one interface.
【Connection】
* Whether it is single pump or double pump, how many interfaces in appearance, only ONE solvent filter can be connected when using.
【Plastic hose】
*The plastic tube has an inner diameter of 7mm and an outer diameter of 13mm, which has a certain elasticity.
If you have any questions, please ASK in free. We will definitely answer your questions actively.
If you buy the accessories together with the vacuum pump, you can enjoy a 5% discount on the accessories! JUST Notify us to get a coupon !
Filters and filtrate bottles can be purchased according to your needs.
Don't worry if you can't buy a diaphragm now. Because the diaphragm is not a universal accessory, it must match the model of the machine you own. If you need to buy a diaphragm, please let us know the model of your vacuum pump and whether it is anti-corrosion. It is best to attach a product picture.
Once we have confirmed the type you need, you can purchase it.
