Application Range of Laboratory Small Oil-Free Diaphragm Vacuum Pumps

Oil-free vacuum pump
As the mainstream vacuum pump product, an oil-free vacuum pump has many advantages that the previous generation products do not have and solves many pain points of rotary vane vacuum oil pumps and circulating water vacuum pumps. This article will take the HAWACH small silent oil-free vacuum pump as an example to introduce the uses of this structure of the pump. HAWACH vacuum pump is a piston-type structure principle, with different pumping speeds, 100A–60L/min; 050B&050A–30L/min; 033A–20L/min; 0200–12L/min and small size. The front end is equipped with a buffer cup, a vacuum gauge, and a regulating valve.

The function of the vacuum pump is to remove gas molecules from the vacuum chamber and reduce the gas pressure in the vacuum chamber to achieve the required vacuum degree. Generally speaking, there is a large range from atmosphere to extremely high vacuum, and so far there is no vacuum system that can cover this range. Therefore, in order to achieve the process indicators, work efficiency, and equipment working life requirements of different products, different vacuum system configurations need to be selected for different vacuum sections. If the oil vapor discharged from the vacuum pump affects the environment, choose the oil-free vacuum pump, or discharge the oil vapor to the outside. Hawach provided Standard Diaphragm Vacuum Pumps and Anti-Corrosion Diaphragm Vacuum Pump for your choice.

Let’s introduce some typical applications:

Waste liquid suction and collection: It can be matched with various equipment that generates waste liquid during work, such as a biochemical analyzer, vacuum purification filter seat, a vacuum manifold, etc. It is only necessary to arrange a suction bottle between the pen and the vacuum pump, and the generated waste liquid can be sucked into the bottle for collection through negative pressure.

Negative pressure suction filtration: It is a method in which the air in the filtration system is drawn away to form a pressure difference between the inside and outside, and the outside air pushes the filtrate through the filter membrane. Most vacuum filtration does not have high requirements for a vacuum, and the use of R300 can meet the needs, and at the same time, it will not produce particularly large noise during operation. In addition, due to the specially designed buffer cup at the front end, the sucked liquid can be collected to prevent the filtrate from being directly sucked into the pump.

Cell room medium waste liquid extraction: used to absorb the supernatant waste liquid after cell culture. This purpose is especially suitable for using an oil-free vacuum pump because it is operated in the cell room clean room, which will not produce an oil mist that pollutes the environment. When purchasing the pump, the customer is recommended to purchase a waste liquid bottle with dual ports, one part is connected to the vacuum pump, and the other part is connected to the suction head. After the pump is turned on, the air in the bottle is sucked away, resulting in a pressure difference between the inside and outside, and the medium will flow to the pressureless medium. The waste bottle flows on one side.

Vacuum suction: It can be used as a vacuum source to generate suction to suck the parts when the equipment processes specific parts. Typical applications are glue dispensers, glue dispensers, and spin coaters. Because the oil-free vacuum pump can be used when it is plugged in, there will be no oil mist pollution during work, so as not to affect the working equipment and processed parts. At the same time, there is no need to add a water source or replace the pump oil, which saves the trouble of maintaining the vacuum pump as auxiliary equipment.
