Description
OIL DIFFUSION PUMP VDP-800

The diffusion vacuum pump from the Vacma brand VDP-800 is a high-vacuum pump with a speed of action of 27,000 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-800 diffusion pump is used with an flow trap or an integrated trap that 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-800 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-800 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.
✔ Upon request, the VDP-800 diffusion vacuum pump can have an electrical connection type: a block of automatic machines or a direct connection via a connector, the price will depend on the configuration. You can buy a VDP-800 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.
