Product Description
Hokaido Roots Vacuum Pump (RV0300)

1. Description:
Modular designed RV series ROOTS vacuum pump can not be operated individually and should be used in connection with backing vacuum pump. The screw pump, oil seal pump and water ring pump are all suitable as backing pump for Roots pump. The Roots pump can be used to pump a mass of condensable gases when it connected with a screw pump or water ring pump.
. This oil-recirculating design is one of the simplest and most reliable vacuum pump available on the world market. These rugged pimps are used in a variety of industries such as packaging and food processing, rubber molding, thermoforming, printed circuit boad testing, hospitals, laboratories, roboticcs, vacuum lamination, printing, and degassing,
2. Features:
Compact, simple design for easy installation and free maintenance
Air-cooled, requiring no oil
Quiet operation
Coutinous duty
High quality European made rotors

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!
