Rotary Screw Vacuum Pump

Name: Rotary Screw Vacuum Pump
Brand: Wan Beardsley Compressor (Shanghai) Co., Ltd.
Availability: InStock

Rated Power: 7.5~90 kW

Product Introduction

Product Features

Energy-efficient and highly efficient, mastering core technologies.

The next-generation screw‑type rotor boasts tooth‑profile accuracy that surpasses industry standards and operates under light loads.

An exceptional split‑type screw compressor host, with direct‑drive motor transmission and zero transmission losses, delivers nearly 100% transmission efficiency!

Vector frequency control delivers rapid response and optimizes current allocation, resulting in significantly enhanced torque‑boost performance.

More efficient and energy-saving

Integrated screw energy-saving host with a permanent-magnet variable-frequency drive system.

Smarter, more human-centered

Interconnected control, early warning alerts, cloud-based internet connectivity, and mobile device management.

More stable and reliable

Silent operation with low vibration, easy replacement, and ultra-low oil content to minimize contamination.

Lower noise

Vacuum performance testing, with a durable and reliable independent air duct, ensures robust operation under all operating conditions.

Equipment Performance Comparison

Product	Liquid-ring vacuum pump	Screw-type vacuum pump
Vacuum pressure	Ultimate vacuum level: 60 Pa	Ultimate vacuum level: 60 Pa
Environment	1. Each vacuum pump must be equipped with a dedicated water supply line and a separate electrical control cabinet. 2. A circulating water pump, cooling tower, and other equipment must be installed to continuously replenish the cooling water supply. 3. In summer, the workshop is filled with water mist, accelerating the corrosion of mechanical components. 4. Environmental requirements necessitate the additional construction of wastewater treatment facilities.	Highly integrated and intelligently designed, the machine can be powered on and operated simply by connecting its front end to a vacuum pipeline and plugging in the power cord—no foundation or additional equipment is required. However, under special operating conditions, auxiliary pre‑filtration equipment may be necessary.
Machine efficiency	1. Efficiency is around 30%. 2. The rated pumping speed of a liquid-ring vacuum pump is specified at an inlet water temperature of 15°C and 100% relative humidity. Typically, when the cooling water temperature exceeds 15°C, the actual pumping speed drops to only 60–80% of the rated value.	1. Efficiency is around 85%. 2. The energy-saving rate can reach 25%–50%.
