Key points for selecting materials for medical pumps

Thread Content

The pharmaceutical industry holds a very important position in the national economy. In the pharmaceutical production process, pumps are used to transport liquids such as drugs, intermediates, pure water, acids, and bases in order to meet the requirements of the manufacturing processes. Depending on the equipment and the conveying medium, some typical pharmaceutical equipment in China. Generally, different types such as vertical multi-stage centrifugal pumps, rotor pumps, metering pumps, and vacuum pumps are used, with centrifugal pumps accounting for 90% of all pumps used in the pharmaceutical industry. The magnetic-driven centrifugal pump, with its special properties as well as features such as no leakage, zero pollution, and environmental friendliness, is highly suitable for use in the pharmaceutical industry. 　　The special characteristics of magnetic pumps used in pharmaceutical equipment The pharmaceutical industry is a specialized sector, and due to the complex properties of the substances used in drug production (pumps are mostly employed for transporting toxic, harmful, flammable, explosive, or corrosive substances), magnetic pumps, as key supporting equipment, have received increasing attention. Their special characteristics are mainly reflected in the following aspects: ① Pumps used in pharmaceutical equipment are subject to extremely strict quality requirements. Although products from other industries such as petroleum and chemicals also have quality requirements, they are difficult to compare with pharmaceuticals. The quality of drugs must comply with the provisions of the Pharmacopoeia of the People’s Republic of China as well as the GMP (Good Manufacturing Practice) requirements. Pumps used in pharmaceutical equipment must also meet GMP requirements. 　　②The pharmaceutical industry has high requirements in all aspects of the production process. In pharmaceutical production, flammable, explosive, as well as toxic and harmful solvents and raw material intermediates are often encountered. Therefore, pumps for medical devices must be selected based on the medium and application. 　　③There are a large variety of drugs, and they are updated rapidly. When the batch number is changed, the equipment pipelines and other components need to be cleaned and disinfected. Pumps used in pharmaceutical facilities should be easy to clean. Requirements regarding the parameters and operating conditions of magnetic centrifugal pumps used in pharmaceutical facilities: ① Parameter range – Compared to pumps used in oil and chemical industries, pumps used in pharmaceutical facilities have a narrower parameter range. According to statistics, the parameter ranges for pumps used in pharmaceutical equipment are roughly as follows. 　　Traffic
