WSU Roots pumpCore models and technical features

Model number	Extraction speed (m ³/h)	Power (kW)	Ultimate pressure (mbar)	Structural characteristics	Adapt to the front-end pump
‌ WSU 1001 ‌	22.5	0.9	0.5	Horizontal air-cooled canned motor with integrated bypass system	SV series rotary vane pump
‌ WSU 2001 ‌	≈65	1.5-2.2	<0.05	Vertical/horizontal options, equipped with pressure balance pipe	D65B and other oil sealed pumps
‌ WSU 251 ‌	100-250	4-7.5	<0.01	Variable frequency compatibility (20-100Hz), fluororubber seal	High flow front-end pump
‌ WSU 501 ‌	>300	11-15	<0.005	Three blade rotor design, low pulsation noise reduction (<75dB)	Multi level series system

Key technological advantages:

Oil free design: driven by a canned motor to avoid lubricating oil contamination of the medium, suitable for high-purity gas transportation;

Variable frequency control: supports speed regulation and extraction speed, increasing energy efficiency by 30%;

High sealing performance: Fluororubber (FPM/FKM) seals, resistant to chemical corrosive gases;

Flexible layout: Vertical/horizontal installation can be switched, saving space.

WSU Roots pumpApplication scenarios and maintenance points

Typical application areas

Industrial vacuum: photovoltaic coating, semiconductor technology, metallurgical heat treatment

Scientific research equipment: Space simulation module, particle accelerator matching

Special media: oxygen-containing gas, radioactive substance (requires PFPE lubricating oil)

Maintenance suggestions

Regular maintenance

Replace bearings and mechanical seals every 2000 hours of operation

Use designated lubricating oil (mineral oil LVO 100 or perfluorooil LVO 400)

Fault prevention

Avoid exceeding the pressure difference limit (>100mbar) to prevent rotor overheating and deformation

The front-end pump needs to maintain a back pressure of<10mbar to ensure efficient operation
