FSP Series
- Description
-
The FSP series variable-pitch screw vacuum pump is a dry-type vacuum pump that achieves gas compression and suction by adjusting the variation in the screw pitch. Its key advantages include high efficiency, energy savings, low vibration, and minimal noise. Constructed from high-strength alloy steel with surface hardening treatment to enhance wear resistance, the pump features a screw design divided into three sections: the suction section, compression section, and discharge section. The screw pitch gradually decreases from the inlet to the outlet, creating a continuous compression chamber. Inside the pump housing, precision helical grooves are precisely engineered, maintaining a tiny clearance between the grooves and the screw’s outer edge to prevent gas leakage.
Characteristics of Dry Screw Vacuum Pumps
Oil- and water-free dry operation delivers a clean vacuum environment, while the frictionless screw-and-housing design ensures extended pump life. The innovative dry rotor design maximizes volumetric efficiency, eliminating the need for oil or water as media—and keeping costs low. Plus, the single-stage design makes it easy to remove solids from inside the pump.
The gas passage inside the pump is short, allowing for rapid gas discharge.
The special coating can handle toxic, corrosive, and condensable gases; its simple design ensures easy maintenance.
Low-speed operation, low vibration, low noise

Material Specifications for Screw Vacuum Pump Components
Note
Screw rod
The variable-pitch screw is made from high-quality ductile cast iron and precisely machined using a five-axis CNC machine, achieving a dynamic balance value of less than 5g. Reduces vibration and noise, with high efficiency
Coating
The materials of the components in contact with the flowing medium (including the inner cavity and screw) can be coated with corrosion-resistant materials. Good corrosion resistance
Synchronous gear
The synchronization gear is the most critical component of a dry screw vacuum pump, as it maintains a precise distance between the screws and ensures their rotation. After undergoing heat treatment, the gear is further refined using tooth-grinding equipment to minimize noise; it features a helical gear design. Long-lasting, silent—sealing is reliable, safe, and leak-free.
Exhaust-side seal
Employing a triple sealing system consisting of mechanical sealing (labyrinth seal) + lip seal + nitrogen gas sealing, the lip seal is positioned at the front of the mechanical seal (labyrinth seal), providing the first line of defense against process media leakage. Inlet-side seal
Employing labyrinth seals combined with lip-type seals, it offers excellent wear resistance and sealing performance. Reliably sealed
Nitrogen Sealing Device
To prevent process materials from entering the gearbox and contaminating the lubricant, implement an air barrier protection system for the seals. Safe and reliable
Nitrogen Purge System
It's convenient to perform nitrogen purging of the internal materials in the screw pump and thoroughly blow out any remaining material when parking. Safe and reliable
Bearing
Using first-tier domestic or imported brand bearings, the service life can reach up to 25,000 hours. Brand: SKF/NSK/FAG
Transmission Method
Adopting an elastic coupling and B5 (B35) mounting method saves floor space; direct coupling is used. Safe and easy to maintain
Flow switch
Protect the vacuum pump by ensuring that cooling water is either not running or flowing in insufficient quantity before starting the pump. Alarm, Parking
Entrance filter mesh
Filter out impurities from the vacuum system to prevent them from entering the screw mechanism. Safe and reliable
Muffler
Featuring noise reduction and gas-liquid separation functions, the drain valve is located at the lowest point of the vacuum pump's internal cavity, allowing liquid materials to be discharged by opening the valve. Safe and reliable
