Description
Product Overview
The KNDVGIEND 2‑piece PTFE diaphragm set is a precision‑engineered component designed specifically for SYSTEC 9000‑1471 and 9000‑1718 vacuum pump models. Each diaphragm measures 40 × 76 mm, mirroring the original OEM specifications to guarantee a seamless fit without the need for modifications. Constructed from high‑grade polytetrafluoroethylene (PTFE), the diaphragms offer exceptional chemical resistance, high‑temperature tolerance, and a low friction surface that prolongs pump life and maintains consistent performance. The set includes two identical diaphragms, providing a ready spare that enables quick swaps and minimizes equipment downtime during routine maintenance or unexpected failures. With a lightweight design—each diaphragm weighs just 1.76 ounces—the components are easy to handle and install, reducing labor effort and the risk of damage during replacement.
Usage
These diaphragms are ideal for a broad range of vacuum applications across laboratory, medical, and industrial environments. Whether you are operating analytical instruments, sterilization equipment, or high‑vacuum processing systems, the PTFE material ensures reliable sealing even when exposed to aggressive solvents, corrosive gases, or elevated temperatures. The diaphragms excel in settings where vacuum integrity is critical, such as mass spectrometry, electron microscopy, and pharmaceutical manufacturing. Their universal compatibility with the SYSTEC 9000 series makes them a convenient choice for technicians and engineers who need a dependable replacement part that integrates effortlessly into existing systems. By maintaining a tight seal, the diaphragms help reduce energy consumption and improve overall system efficiency, delivering cost savings over the lifespan of the equipment.
