Vacuum pumps
What is a dry-running rotary vacuum pump?
A dry-running rotary vacuum pump is a reliable, powerful, compact vacuum pump. The pump is oil-free making it suitable for industrial applications that require reliable and fast vacuum. Rotary vane vacuum pumps can be used for various types of packaging processes.What are the advantages of a dry-running rotary vacuum pump?
There are a number of advantages of a rotary vane vacuum pump:- Oil-free operation, high availability and operational reliability. This due to self-lubricating and wear-resistant rotary sliders made of special graphite, life-lubricated bearings and a robust construction.
- Compact size. this allows the pump to be easily installed almost anywhere.
- Energy-efficient drive with efficient operation.
- Simple maintenance that can be performed by yourself.
- Besides replacing the slides and filters on time and regular checks, no additional maintenance is required.
How a dry-running rotary vacuum pump works?
- The vacuum pump consists of a cylindrical pump housing and an electric motor. Inside the pump housing is an eccentrically placed rotor with vacuum vanes. The vacuum vanes are also called vanes.
- The rotor in the pump housing rotates, causing the vanes to move toward the pump housing wall. This creates chambers in a 360-degree circle.
- The air is drawn in, compressed and then pushed out again.
- In this way, the pump sucks causing vacuum to build up.
Characteristics of dry-running vacuum pumps
