Laboratory vacuum pumps

A vacuum pump is a device used to create vacuum-like conditions. By creating a vacuum, a vacuum pump is designed to remove gases in an enclosed space. Pumps can be divided into gas-transfer vacuum pumps and pumps that bind gas depending on their physical operating principles. Since different vacuum levels and pumping capacities are required, various pump models and pump combinations are used. In addition, vacuum pumps can differ in the way they operate, so we divide them into: volumetric, jet, ion-sorption, ion-magnetic, molecular, condensation, adsorption and ionic. In the case of laboratory vacuum pumps, three parameters characterize these devices and are the most important da effectiveness of their operation, they are: the final pressure (the smallest value that the device can achieve), the pumping rate, the dependence of the rate on the pressure, and the efficiency. In addition, an important step is to pay attention to the maximum pressure that can be obtained at the outlet of the pump. Pumping speed, is a measure of the amount of gas that is sucked from the inlet to the unit of time by the pump. The second feature is the operating pressure range, the vacuum pump for a certain range of pressures at the inlet has a constant and maximum suction speed. The third is the flow rate, this is the velocity multiplied by the gas pressure at the inlet. There are other features to distinguish different types of vacuum pumps, such as the materials from which they are made and the very nature of the device's operation. Vacuum pumps are made of robust materials such as stainless steel, cast iron, bronze and brass. As a result, they show high resistance to mechanical damage, the effects of corrosive agents and ensure reliable operation in all conditions. Some pump models have been adapted for ATEX stress. In addition, some models of vacuum pumps are equipped with the option of remote control via a computer or through another device. Vacuum pumps are used in the chemical, pharmaceutical, food, textile as well as metallurgical industries, among others. Diaphragm pumps can be used for continuous pumping of vapor-free gases. These devices are equipped with a flexible diaphragm, which prolongs its life. On a large scale, diaphragm pumps are used in chemical laboratories, microbiological laboratories as well as in sewage treatment plants and other such facilities. PDiaphragm pumps can also be used for pumping non-aggressive gases because all components that connect to the pumped media are made of aluminum or safe and suitable other materials. Chemically resistant diaphragm pumps are made of highly resistant materials, gases and vapors come into contact only with chemically resistant fluoroplastic material. A specially designed condensate outlet ensures recovery of almost 100% of the solvent. Chemically resistant diaphragm pumps are ideal for general and industrial laboratories. Another type of vacuum pumps are oil pumps, which are ideal for processes that require low end vacuum at medium to high gas flow rates. Oil pumps are compact and lightweight, in addition to being very efficient. Some of the devices can be retrofitted with, for example, an oil mist filter, VS16 valve and IP40 safety class. Another type of pumps are hybrid pumps, which effectively minimize the adverse effects of corrosive vapor condensation processes. Hybrid pumps combine elements of a two-stage vane pump and a two-stage diaphragm pump. The diaphragm pump excels at removing gases from the vane pump's oil reservoir, allowing the partial pressure of solvent vapor, oxygen and corrosive gases to be kept extremely low. The characteristics of hybrid pumps are high tolerance to water vapor, tightness of the pump mechanism at shutdown and also high efficiency of the gas ballast mechanism.We invite you to make inquiries at our company.
