OIL DIFFUSION PUMP VDP-250: description, advantages, scope of application, technical specifications, dimensional drawing, promotional materials

  • The diffusion vacuum pump from the Vacma brand VDP-250 is a high-vacuum pump with a speed of action of 2700 l/s and is used in conjunction with an oil pre-vacuum pump. The pre-vacuum pump is necessary for pre-pumping and for foring the pumped gas from the outlet pipe of the diffusion vacuum pump. As a rule, the VDP-250 diffusion pump is used with the nitrogen filling trap or the water flow trap, which reduce the reverse flow of working fluid vapors into the pumped volume. The mineral vacuum oil is used as the working fluid in the pump, thanks to which the operational properties and durability of vacuum equipment are improved. The VDP-250 vacuum pump includes a steam line - a four-stage nozzle system with a fairly simple principle of operation - it consists in the process of diffusion of the molecules of the pumped gas into the jet flowing from the nozzles of the working fluid (steam).

  • ✔ According to consumer reviews, the VDP-250 diffusion vacuum pump is a reliable, durable equipment with a large working resource for working in high vacuum conditions where high pumping speed is required.

  • ✔ On request, the VDP-250 diffusion vacuum pump can have an electrical connection type: automatic control unit or direct connection via connector, ISO-K type of inlet flange, the price will depend on the configuration. You can buy a VDP-250 diffusion pump at a price from a Russian manufacturer on our website, for this you need to send an application, after which the specialists of JSC "Vacuummash" will contact you.
