Oil diffusion/Oil Vapor Jet Pumps
PDF 979.4 kB
Leybold DIP series of oil diffusion pumps are high vacuum pumps (<10-2 mbar). They are always operated in conjunction with fore vacuum pumps. The DIP series oil diffusion pumps are water cooled and utilize the oil diffusion pump principle in their operation. They are employed in high-vacuum technology to evacuate vacuum chambers. They achieve their highest pumping speeds in pressure ranges from 10-2 to 10-7 mbar.
Leybold DIP oil diffusion pumps have a special design including a four-stage nozzle system and an over decade proved heater radiator principle, short heat up time leads to optimized cycle times in your processes.
The DIP series are best for applications or processes, where you need high pumping speed in low pressure ranges of 10-4 mbar. Additionally, Leybold DIP oil diffusion pumps require little maintenance due to no wear caused by revolving parts. The proved heater principle and maintenance-friendly design are further advantages of the DIP series.

The DIP line offers
The DIP line has some beneficial attributes that are supporting your processes and applications.
The DIP pumps are fitted with a four-stage nozzle system made of light-alloy metal and an integrated cold cap baffle on top to minimize the oil-backstreaming in your process.
To prevent fluid from flowing back into the vacuum chamber, the DIP series pumps are fitted with a water-cooled cold cap baffle in the area of the intake high vacuum port.
A water-cooled fore vacuum baffle located on the fore vacuum side effectively prevents fluid being swept into the fore vacuum unit.
The heating principle of the DIP oil diffusion pumps works like a direct radiator in the oil fluid. By this, a direct energy transfer into the oil fluid is ensured which leads to faster heat-up times and therefore lower power demands in the process.
The heating cartridges can be easily replaced when required. It is not necessary to dismantle the pump to do so.
To protect the heating element, a thermostat sensor is attached on the heater element which protrudes from the fluid; this will switch off the pump’s heaters as soon as the temperature set at the safety thermostat is exceeded. The overheating protection switch must be integrated into your system control so that it will safely switch off the power.
Energy savings up to 30% without pump performance loss
Oil diffusion pumps require a certain minimum oil temperature for operation. Commonly, 100% of the installed heating power is constantly utilized. The innovative Leybold energy efficiency control unit for diffusion pumps cuts power consumption by up to 30% since the supplied power is significantly reduced after the pump has attained its operating temperature. Further savings result from the utilization of the standby mode at a reduced temperature. Additional saving at cooling chiller system “Energy they I don’t need, reduced my cooling installed capacity, for water”!
