Product Specification

Wordfik Custom Single Stage Oil-Sealed Rotary Vane Roots Vacuum System

Overview

The Wordfik Custom Single-Stage Oil-Sealed Rotary Vane Roots Vacuum System is an engineered vacuum solution that combines a Roots vacuum pump as the main booster with a reliable oil-lubricated rotary vane pre-stage pump. This proven combination delivers rapid evacuation and stable high-vacuum performance across a wide range of industrial applications.

The system operates through a two-stage process: the pre-stage pump quickly lowers system pressure to the required starting range for the Roots vacuum pump, which then significantly increases exhaust speed and operating pressure to meet demanding process needs. This efficient pairing—often described in the industry as the "classic solution" for achieving both low ultimate pressure and high pumping speed—makes it an ideal choice for processes requiring fast pump-down and consistent vacuum integrity.

Engineered for durability and low maintenance, the system integrates essential auxiliary components including an oil circulation unit, cooling system, electromagnetic anti-backflow valve, and an automatic PLC controller. These elements work together to prevent oil return during shutdown, maintain optimal operating temperatures, and enable smooth, automated operation. Designed with contamination resistance in mind, the system delivers clean and reliable performance even in sensitive or harsh industrial environments.

Each system is fully customizable—from component selection to 3D design and delivery—ensuring it precisely matches the specific requirements of your application.

Key Features

Proven Roots + Rotary Vane Combination – Integrates a Roots vacuum pump as the main booster with an oil-sealed rotary vane pre-stage pump. This classic configuration delivers both high pumping speed and deep ultimate vacuum, making it the preferred solution for demanding industrial processes.

Rapid Evacuation & Stable High Vacuum – The pre-stage pump quickly lowers system pressure to the Roots pump's starting range, after which the Roots pump significantly increases exhaust speed and operating pressure. The result is fast pump-down times and consistent vacuum levels throughout the process cycle.

Energy Efficient – Optimized pump combination reduces overall power consumption compared to single-stage solutions operating alone at low pressures.

Contamination-Resistant Design – Built to deliver clean, reliable performance even in sensitive or harsh industrial environments. Optional dust filters and auxiliary components further protect against particle contamination.

Automated & Low Maintenance – Equipped with a PLC controller (customizable with multi-language support) for automated operation. The electromagnetic anti-backflow valve prevents oil return during shutdown, while the cooling system and oil circulation unit maintain optimal operating temperatures.

Wide Pre-Stage Pump Compatibility – The pre-stage pump can be selected from Wordfik's PVX series, offering pumping speeds from 10 m³/h to 750 m³/h with ultimate pressures of 10-100 Pa. This flexibility ensures the system can be tailored to applications ranging from light-duty to heavy-industrial.

Achievable Vacuum Level – The complete system achieves vacuum levels of 1-10 Pa, delivering the deep vacuum required for critical processes such as vacuum coating, transformer drying, and semiconductor manufacturing.

Fully Customizable – From pump selection to auxiliary systems, tank sizes, and control interfaces, every aspect of the system can be tailored to your specific requirements. 3D design and delivery ensure seamless integration into your existing infrastructure.
