Vacuum Pump Head

Product Specifications

Technical details and manufacturing context for Vacuum Pump Head

Definition

The vacuum pump head is the core functional component of a gas flushing unit or vacuum pump system, responsible for generating the necessary vacuum pressure by removing gases from a sealed chamber. It typically houses the pumping mechanism (such as rotary vanes, diaphragms, or scrolls) and interfaces directly with the system being evacuated. The pump head operates by mechanically creating a sealed, expanding volume within its chamber. As the internal mechanism (e.g., rotor, piston, or diaphragm) moves, it traps gas from the inlet port, compresses it, and then expels it through the exhaust port, thereby reducing pressure in the connected system. This component is available in materials such as cast iron, aluminum alloy, and stainless steel, and is characterized by parameters including nominal diameter (15–100 mm, ISO 6708), pumping speed (4–100 m³/h at 50 Hz, ISO 21360), ultimate pressure (0.5–100 Pa, ISO 21360), motor power (0.75–7.5 kW), voltage (220–480 V, three-phase, IEC 60038), frequency (50–60 Hz, auto-switching), operating temperature (-10–40 °C), maximum inlet pressure (0.03–0.1 MPa), noise level (55–75 dB(A) at 1 m, ISO 3744), ingress protection (IP54–IP55, IEC 60529), material grade (HT250–QT500, GB/T 1348), and weight (15–120 kg without motor). These values are reference ranges and must be verified for the specific model and application. The pump head is selected based on required vacuum level, pumping speed, and compatibility with the system's piping and electrical supply. It interfaces with the motor, inlet and exhaust piping, and control systems. When evaluating a pump head, confirm the actual performance data, material grades, and standards compliance with the legal manufacturer or supplier. Maintenance signals include unusual noise, reduced pumping speed, or increased ultimate pressure, which may indicate wear or contamination. Failure boundaries include exceeding the maximum inlet pressure or operating outside the temperature range, which can damage the component. Always consult the manufacturer's documentation for installation, operation, and maintenance guidelines.

Working Principle

The pump head operates by mechanically creating a sealed, expanding volume within its chamber. As the internal mechanism (e.g., rotor, piston, or diaphragm) moves, it traps gas from the inlet port, compresses it, and then expels it through the exhaust port, thereby reducing pressure in the connected system.

Components / BOM

Rotor Part
Rotates within the housing to create the pumping action, often with vanes that slide to maintain contact with the housing wall.

Material: Steel or Carbon Composite
Housing/Casing Part
Encloses the pumping mechanism, provides structural integrity, and contains the inlet and exhaust ports.

Material: Cast Iron or Aluminum
Inlet/Exhaust Valves Part
Control the flow of gas into and out of the pumping chamber, ensuring one-way flow and preventing backflow.

Material: Stainless Steel or Rubber
Sliding Vanes Optional
Slide out of the rotor slots to sweep the chamber and seal against the casing wall, on vane-type heads.

Frequently Asked Questions

What materials are available for the vacuum pump head?

The vacuum pump head is available in cast iron, aluminum alloy, and stainless steel. The specific material grade (e.g., HT250–QT500 for cast iron) should be confirmed with the manufacturer for the intended application.

What is the typical pumping speed range?

The pumping speed ranges from 4 to 100 m³/h at 50 Hz, as per ISO 21360. The actual value depends on the model and operating conditions, so verify with the supplier.

What is the maximum inlet pressure?

The maximum inlet pressure is 0.03 to 0.1 MPa. Exceeding this range may damage the pump head. Always check the manufacturer's specifications for the specific model.

What are the electrical requirements?

The pump head typically requires a three-phase power supply with voltage ranging from 220 to 480 V (IEC 60038) and frequency of 50–60 Hz (auto-switching). Motor power ranges from 0.75 to 7.5 kW. Confirm exact requirements with the manufacturer.
