This is a medical rubber working chamber diaphragm. It’s made for respiratory equipment in the healthcare industry. It’s a critical part of
Pump Valves And Sealing Parts For Testing Equipment and
Testing Instrument Sealing Parts.It has two main parts: a bolt section and a diaphragm disc section. The bolt section is used to connect and fix things. It has a standard threaded structure. This makes it easy to assemble with threaded holes on equipment. The diaphragm section is shaped like a disc. It has a multi-layer annular corrugated or folded structure. This structure makes the diaphragm more flexible and easier to change shape.It’s made of materials that meet the performance standards of
Medical Silicone Seal (for the diaphragm part). It gives reliable fluid control and sealing support to respiratory and fluid delivery medical devices. It also matches the precision requirements of Detection Device Seals.
Product Features
1. Functions
1)Precise Fluid Delivery:It’s used in medical equipment like infusion pumps and syringe pumps. The diaphragm moves back and forth. This movement precisely controls how much medical fluid is delivered and how fast it’s delivered. When the diaphragm moves outward, the pump chamber gets bigger and the pressure inside goes down. This pulls medical fluid into the pump chamber. When the diaphragm moves inward, the pump chamber gets smaller and the pressure inside goes up. This squeezes the medical fluid out of the pump chamber. This lets drugs be delivered precisely. It meets the strict requirements for drug dosage and infusion speed in different treatment scenarios. Its delivery precision is as good as the functional reliability of Testing Pump Valves in high-precision fluid systems.
2)Isolation and Anti-Contamination:The diaphragm works as a barrier. It separates the fluid being delivered (like medical fluids and blood) from other mechanical parts of the pump. This stops the fluid from getting dirty effectively. It also stops the fluid from corroding the internal parts of the pump. This makes sure the fluid stays pure and the pump lasts longer. For example, in extracorporeal circulation equipment, it can stop blood from touching the metal parts of the pump directly. This reduces the risk of blood damage and thrombus formation. Its isolation effect meets the hygiene standards of
Sterile Medical Seals and
Medical Device Seals in important medical fluid uses.
3)Pressure and Flow Regulation:You can control how often the diaphragm moves and how far it moves. This lets you adjust the pressure and flow output of the pump valve. Some medical equipment needs to change fluid delivery parameters in real time based on the patient’s condition. The diaphragm pump valve can respond to control commands flexibly. This lets it adjust pressure and flow dynamically. This regulatory capability helps with the performance of Lab Equipment Gaskets in keeping the system’s fluid dynamics stable.

2. Required Characteristics
1)Biocompatibility:It may touch medical fluids, blood, and other things that are directly related to the human body. So the material of the diaphragm pump valve must have excellent biocompatibility. It’s non-toxic, won’t cause allergies, and won’t irritate. It can’t harm human health. It also can’t have chemical reactions with the fluid that change the fluid’s properties. This is a basic requirement for all
Medical Grade Silicone Seals and Detection Device Seals that touch biological fluids.
2)Chemical Stability:It must stand various chemical substances commonly used in the medical field. Things like acid-alkaline medical fluids and disinfectants. When it touches different chemical reagents for a long time, the diaphragm and other parts can’t have problems. Like swelling, corrosion, or getting worse. This keeps the pump valve working normally. This stability meets the material standards of Pump Valves and Sealing Parts for Testing Equipment in harsh medical environments.
3)Sealing Performance:It must have very high sealing capabilities. It stops fluid from leaking effectively under different pressure conditions. There must be good sealing between the diaphragm and the pump chamber wall. There also must be good sealing at the bolt connection points. This avoids inaccurate dosages or equipment failures caused by leakage. This sealing reliability is as good as that of
Medical Vial Cap Seals and core Medical Seals in precision sealing scenarios.
4)Flexibility and Durability:The diaphragm must be flexible. This lets it move back and forth and change shape many times without cracking. At the same time, the whole pump valve must be durable. It can stand long-term high-frequency operation. Mechanical parts (like bolts) can’t loosen or wear easily. The diaphragm can’t get old or damaged easily. This makes sure the equipment is reliable and stable. This durability meets the service life standards of Testing Instrument Sealing Parts in high-intensity use scenarios.
5)Precise Flow Control Capability:The design and manufacturing of the pump valve must make sure fluid flow and pressure are controlled precisely. The error range is very small. This meets the strict requirements for drug or fluid delivery precision in medical treatment. This precision matches the accuracy requirements of Testing Pump Valves and Detection Device Seals.
6)Ease of Cleaning and Disinfection:In medical environments, the pump valve needs to be cleaned and disinfected regularly. This stops microbes from growing and cross-contamination. So its material and structure must be easy to clean. It must also stand common disinfection methods. Like high-temperature and high-pressure sterilization and chemical disinfection. The disinfection process can’t affect the pump valve’s performance. This meets the hygiene standards of Sterile Medical Seals and other medical components in clinical settings.
