Diffusion pumps – size DN 40

The high-performance HSR small diffusion pumps are air-cooled, feature a vacuum flange DN 040 ISO-KF, and are equipped with an integrated baffle as well as a thermal protection switch.

Features:

  • Integrated baffle

  • Compact design

  • Air-cooled with integrated ventilator 

  • Suitable for mineral oils, silicone oils, or pentaphenyl ether

PDB STANDARD DN 40 TECHNICAL DATA
Diffusion pumps with integrated water baffle  – Size DN 63 to DN 250

This series features, as its main characteristic, an integrated, optically dense baffle. The pump housings are made of stainless steel. The nozzle system consists of aluminum pressure parts and can be easily removed for cleaning. A thermal protection switch mounted on the pump housing prevents the propellant from overheating. The water cooling circuit consists of a stainless steel tube that is soldered onto the pump housing.

Features:

  • Compact design

  • Integrated water baffle

  • Pump housing and connection flange made of stainless steel

  • Suitable for mineral oils, silicone oils, or pentaphenyl ether

Diffusion pumps with cold cap or baffle cap – Size DN 320 to DN 1000

This water-cooled pump series has a pumping speeds ranging from 5,000 to 50,000 l/s and has been specifically developed and optimized for industrial high-vacuum applications with high pumpig speeds. For applications in the range of 10-4 mbar, our diffusion pumps are equipped with the so-called baffle cap, which provides a high gas throughput. 

The optionally available baffle cap reduces the pumping capacity by 20%. However, it significantly decreases oil backstreaming. Even better results regarding backstreaming are achieved with separate baffles, which reduce the pumping capacity by 50%.

Features:

  • Robust design

  • Low ultimate pressure

  • Integrated cold cap or baffle cap

  • Low propellant consumption due to forevacuum baffle

  • Short warmup time

  • Suitable for mineral oils, silicone oils, or pentaphenyl ether
