Component Specifications

Definition
Inlet/outlet ports on vacuum pumps are critical interface components designed to establish and maintain airtight connections between the pump and external systems. The inlet port serves as the entry point for gases being evacuated from the vacuum chamber, while the outlet port expels compressed gases to the atmosphere or to subsequent processing stages. These ports feature standardized flange configurations, sealing surfaces, and mounting provisions to ensure leak-tight operation under varying pressure differentials.
Working Principle
Inlet ports create a pressure differential that draws gases into the pump's compression mechanism, while outlet ports release compressed gases against atmospheric or system backpressure. Both ports utilize precision-machined sealing surfaces and standardized connection interfaces to maintain vacuum integrity and prevent contamination ingress.
Materials
Stainless steel (304/316), aluminum alloys (6061-T6), brass (C36000), with optional PTFE or Viton sealing elements. High-vacuum applications may use electropolished stainless steel or aluminum with copper gaskets.

Frequently Asked Questions

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

ISO-KF (Klein Flange) uses clamp connections with elastomer seals for medium vacuum (10^-9 to 10^3 mbar), while CF (ConFlat) uses metal gaskets and bolted flanges for ultra-high vacuum applications (below 10^-9 mbar).

How do I prevent leaks in vacuum pump ports?

Ensure proper surface finish (Ra ≤ 0.8 μm), use correct gasket materials (Viton for general vacuum, copper for high vacuum), follow specified torque values during assembly, and perform regular helium leak testing.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
