Vertical Claw Vacuum Pump Series: Designed for Stable Vacuum Performance

The Vertical Claw Vacuum Pump Series is designed for industrial vacuum applications requiring stable vacuum performance and compatibility with a variety of organic solvent media. According to the product specifications, the series offers multiple pumping capacities, corrosion-resistant structural materials, and several configuration options that allow it to meet different process requirements.

The equipment is available in six pumping speed configurations ranging from 50 L/s to 300 L/s, with motor power from 5.5 kW to 30 kW, enabling users to select an appropriate model according to process capacity.

Vacuum Performance

One of the important technical indicators of a vacuum pump is its achievable vacuum level.

The Vertical Claw Vacuum Pump Series provides:

• Ultimate inlet pressure ≤30 Pa (Absolute)
• Four-stage compression models can achieve ≤3 Pa (Absolute)

These parameters indicate the vacuum level that the equipment can reach under specified operating conditions and provide users with multiple configuration options for different vacuum process requirements.

The maximum exhaust working pressure is 150 kPa (Absolute).

Compatible Working Media

According to the manufacturer's specifications, the Vertical Claw Vacuum Pump Series is suitable for handling various organic solvent media, including:

• Benzene derivatives
• Alcohols
• Lipids
• High-boiling-point organic solvents
• Low-boiling-point organic solvents

When selecting a vacuum pump, verifying media compatibility is essential because different chemical media may require different material selections and sealing configurations.

Multiple Pumping Speed Options

The Vertical Claw Vacuum Pump Series offers the following nominal pumping capacities:

Corresponding motor power ranges include:

• 5.5 kW
• 7.5 kW
• 11 kW
• 15 kW
• 18.5 kW
• 22 kW
• 30 kW

This range allows users to choose equipment according to production scale and system design requirements.

Composite Shaft Seal Structure

The pump adopts a composite shaft sealing system, consisting of:

• Expansion ring
• Labyrinth seal
• Spiral reverse thrust structure
• Nitrogen protection
• Lip seal

This multi-component sealing structure forms part of the overall sealing design of the equipment.

Materials Used in Key Components

Material selection directly affects equipment durability and compatibility with process media.

According to the product specifications:

These material configurations are intended to provide corrosion resistance for components exposed to process media.

Bearing Configuration

The Vertical Claw Vacuum Pump Series uses bearings supplied by internationally recognized manufacturers, including:

• FAG
• NSK
• SKF

Users can select the appropriate bearing configuration according to equipment requirements.

Starting Methods

The equipment supports two starting modes:

• Atmospheric direct starting
• Variable-frequency control

Variable-frequency configuration allows users to adjust operating conditions according to actual production requirements when applicable.

Motor Configuration

The standard motor specifications include:

• AC380V
• 50 Hz
• Explosion-proof grade: EXdIIBT4/CT4
• Protection grade: IP55

The transmission system adopts a direct-coupling structure.

Cooling System

Two cooling methods are available:

• Tops Cold Agent
• Direct water cooling

According to the manufacturer, the Tops Cold Agent uses a polyol mixture with cooling performance superior to conventional ethylene glycol solutions.

The normal circulating water consumption is approximately:

1 m³/h

Connection Size

The equipment provides the following interface specifications:

These dimensions can be used when matching the vacuum pump with the piping system.

Operating Noise

Under normal operating conditions, the equipment produces a noise level of:

≤78 dB

This value can be used as a reference when planning equipment installation and plant layout.

Conclusion

The Vertical Claw Vacuum Pump Series provides a combination of configurable pumping speeds, multiple cooling options, composite shaft sealing, corrosion-treated flow passages, and industrial-grade component selection.

Its technical specifications indicate compatibility with a variety of organic solvent media, including benzene derivatives, alcohols, lipids, and both high- and low-boiling-point organic solvents. Multiple pumping capacities, explosion-proof motor options, and standardized interface sizes provide flexibility for integration into different industrial vacuum systems.
