Support for patient care: KNF pump drives medical suction devices.

  • UPDATE
  • PRODUCT

Medical suction devices are essential in countless emergency procedures and surgeries, helping clinicians keep airways and surgical fields clean. KNF's diaphragm suction pumps provide the high vacuum performance that is crucial for these systems. According to estimates by the World Health Organization (WHO), over 300 million surgical procedures are performed worldwide each year, and the number of emergency medical service (EMS) deployments is even higher. In most cases, medical suction devices are indispensable for patient safety and care. These systems utilize diaphragm vacuum pumps to ensure rapid and reliable suction necessary for medical procedures.

All pickups leveled up: Electric diaphragm vacuum pump for pick-and-place systems.

  • UPDATE
  • PRODUCT

In pick-and-place systems that use vacuum grippers, all operations depend on stable vacuum performance. KNF's electric diaphragm vacuum pumps generate vacuum directly where needed, eliminating the need for compressed air infrastructure, resulting in a compact, reliable, and energy-efficient system. Designed to meet the needs of modern pick-and-place automation, the demands on vacuum systems are increasing due to shorter cycle times, format changes, and the requirement for stable operation 24/7. KNF's pumps assist engineers in achieving the following: - Improving throughput without compromising accuracy - Designing compact, flexible, and decentralized systems - Reducing energy consumption and operational costs - Maximizing system uptime

KNF Gas Pump Performance Comparison

  • PRODUCT

You can refer to the flow rates, maximum allowable discharge pressures, and achievable vacuum levels of KNF gas pumps (gas transfer pumps) by pump model type. The pumps include standard pumps, process pumps (heat-resistant, explosion-proof, high flow, high discharge), and micro pumps (small-sized, low flow). We hope this information will be helpful when selecting a pump.
