Product Description
18 Months Warranty Dry Screw Vacuum Pump(RSE630)

Product features:

1. RSE series dry screw vacuum pump(RSE 630) is single stage compression, simple structure.
Partition plate in the cavity, the exhaust path is simple and short, and reactant gas is easily discharged.
2. The high pressure end of the exhausted temprature deposition is easily fixed, and helical rotor with sedment removed.
3. The case of a single-stage exhaust, no change in the internal volume of the continuous operation at atmospheric pressure, and a locking phenomenon does not occur during operation. For symmetrical rotation structure, vibration rate is less than 10u.
4. Low operation noise.
5. The spiral structure of the single segment, the helical part of the maintenance is very easy. With corrosion-resistant materials, only the replacement of the sealed classes of the consumption goods can save on maintenance costs.

Products application:
Widely used in vacuum coating, oven, heat treatment, pharmaceutical, chemical applications, semiconductor, LED and solar cell industry, etc...

Our company has pass:SGS, CE, RoHS

The working principle

Hokaido RV series roots vacuum pump is composed of a pair of synchronous high-speed rotor like the number"8"and of two semicircular cavity.

Improve the extraction rate of the vacuum pump greatly within the scope of work effectively
The motor diversity

To ensure the normal use, every Hokaido roots vacuum pump motor can be used air cooling or water cooling.
Pump overall uses aluminium alloy or cast iron material, realizes the advantages of heat cooling faster, strong corrosion resistance, etc
Cast iron + water cooled motor
Alloy + fan cooled motor

Simple structure  Maintain convenience

Rotor type line through carefully designed and using the circular arc rotor way, make the design of pump more compact

Extraction effect is more prominent, greatly improve pumping speed level compared with other manufacturer.

Easy to maintain, very low maintenance cost
High purify vacuum
Roots vacuum pump cavity do not have reaction medium with air
To ensure that the pumped gas is from secondary pollution, realize High purify vacuum
Contactless operation
Process and measure the rotor precisely with German Zeiss three coordinates detector, the Japanese Mazak machining center's equipment and so on.
With a good collection of symmetry, realize ultra low noise, long life
Universal pump   Booster pump
Roots pump also calls the booster pump, can be together pump system with screw pump, vane pump, water ring pump, plunger pump, molecular pump, greatly improve the extraction rate and vacuum degree.
Can be increase more than 10 times of vacuum degree under normal circumstances!
Screw pump/roots pump system
Double stage pump/roots pump system
