Water-Cooled Claw Vacuum Pump ZSV650 648m³/h 775m³/h 80mbar Wordfik Brand

Overview

The Wordfik ZSV650 is a high-capacity water-cooled dry claw vacuum pump engineered for demanding industrial applications requiring oil-free, contamination-free vacuum performance at scale. As a flagship model in Wordfik's ZSV series, this rotary volumetric vacuum pump features two conjugate meshing claw-shaped rotors driven by synchronous high-precision gears. The rotors operate without contact between each other or the pump housing, leaving only a small gap — a design that ensures reliable operation, minimal wear, low vibration, and low noise.

The ZSV650 delivers a powerful pumping speed of 648 m³/h at 50Hz and 775 m³/h at 60Hz, achieving an ultimate pressure of 80 mbar under water-cooled operation. Powered by an 11 kW (50Hz) or 13.2 kW (60Hz) motor, the ZSV650 is suitable for low and medium vacuum fields, primarily extracting air and other dry gases. It can be used independently, in series or parallel configurations, or as a fore pump for other vacuum systems.

Key Features

• 100% Oil-Free Operation – Delivers completely dry, contaminant-free vacuum without oil or any other media in the pump chamber, protecting both the process and the environment.

• Water-Cooled Design for Maximum Performance – The water-cooled configuration achieves an exceptional ultimate pressure of 80 mbar, providing deeper vacuum than air-cooled alternatives while maintaining stable operating temperatures during extended continuous operation.

• Non-Contact Rotor Design – Two claw-shaped rotors rotate in opposite directions without touching each other or the housing. This eliminates mechanical friction, reduces wear, and ensures long service life.

• High Capacity for Demanding Applications – With 648-775 m³/h pumping speed and a 3 inch inlet connection, the ZSV650 delivers exceptional air volume for the most demanding industrial processes.

• Corrosive Gas Capability – Can absorb corrosive, toxic, radioactive, and dusty gases, making it suitable for challenging industrial environments.

• Low Noise and Vibration – Engineered for smooth, quiet operation with low vibration levels, creating a safer and more comfortable working environment.

• No Regular Maintenance Required – The non-contact operation means no wearing parts to replace, significantly reducing operating costs and downtime.

• Low Operating Temperature – No metal friction within the pump chamber ensures low operating temperatures, extending component life.

• Versatile Configuration – Can be used alone, in series (to increase vacuum degree), or in parallel (to increase pumping rate), and also serves as a fore pump for other vacuum systems.

• Heavy-Duty Construction – With a weight of 380 kg and robust dimensions of 1110×580×800 mm, the ZSV650 is built for long-term reliability in industrial environments.
