Component Specifications

Definition
Inlet/outlet ports in vacuum pumps are critical interface components designed to connect the pump to external systems, ensuring controlled intake of gases/vapors and exhaust of processed media. These ports maintain vacuum integrity while allowing connection to piping, chambers, or other equipment through standardized flanges or threaded fittings. They are engineered to minimize pressure drops, prevent leaks, and withstand operational stresses including thermal cycling and chemical exposure.
Working Principle
Inlet ports create a controlled pathway for gases/vapors to enter the pump's compression chamber, while outlet ports expel processed media after compression. Both function by maintaining airtight seals through gaskets or O-rings, with geometries optimized to reduce turbulence and backflow. Port sizing and design directly influence pump efficiency by minimizing flow resistance and maintaining consistent pressure differentials.
Materials
Stainless steel (304/316), aluminum alloys, brass, or engineered plastics (PTFE, PEEK) depending on chemical compatibility and pressure requirements. Seals typically use Viton, EPDM, or silicone O-rings.

Frequently Asked Questions

What's the difference between ISO-KF and CF flange connections?

ISO-KF (Klein Flange) uses a clamp and O-ring for quick connections up to DN50, while CF (ConFlat) uses a metal gasket and bolts for ultra-high vacuum applications with better leak-tightness.

How often should port seals be replaced?

O-rings and gaskets should be inspected quarterly and replaced annually or when leaks exceed 1x10^-9 mbar·L/s, depending on operational cycles and media compatibility.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
