❓ Frequently Asked Questions (FAQ)
❓ What makes the KVSP series vacuum pumps "oil-free"?
The KVSP series features a dry screw design that operates without any oil in the pumping chamber. This prevents oil contamination, making it ideal for highly sensitive processes that require a clean vacuum environment.
❓ What is the ultimate vacuum pressure of these pumps?
The standard KVSP and KVSP-H series achieve an ultimate pressure of ≤1 Pa, while the KVSP Combined Units can reach an ultra-high vacuum level of ≤0.01 Pa.
❓ How does the variable pitch rotor design benefit operation?
The variable pitch rotor optimizes gas compression efficiency throughout the pump chamber, which significantly reduces power consumption and heat generation compared to fixed-pitch designs.
❓ Are these dry screw vacuum pumps noisy?
No, the KVSP series is engineered for low noise operation. With an integrated silencer, the noise level is maintained between ≤66 and 76 dB(A), depending on the specific model.
❓ Can the KVSP pumps be customized for harsh or corrosive environments?
Yes. Kaishan offers customizable options including nitrogen purge systems, specialized rotor coatings, and explosion-proof designs to ensure reliable operation under demanding industrial conditions.
❓ Who manufactures the KVSP series vacuum pumps?
They are developed and manufactured by Chongqing Kaishan Fluid Machinery Co., Ltd., a wholly-owned subsidiary of Kaishan Group (stock code: 300257), ensuring high-quality standards with over 85% of key components produced in-house.
