2507-A Single-Head WOB-L Piston Vacuum Pump
Product Overview
The 2507-A Single-Head WOB-L Piston Vacuum Pump is a compact, oil-less vacuum pump built for laboratory, industrial, and composites applications that demand clean, dependable vacuum. Running on standard 115V / 60Hz power, it delivers up to 2.32 cfm (65.8 L/min) of open flow and pulls a maximum vacuum of 26.6 in-Hg (90.9%), enough performance for demanding vacuum infusion work as well as everyday lab and industrial vacuum tasks.
Because the 2507-A uses a low-vibration WOB-L piston mechanism instead of an oil-lubricated design, process air stays free of lubricant contamination, and the pump runs quieter than typical rotary vane or oil-sealed alternatives. A thermally protected motor (145 °C ± 5 °C cutoff) safeguards against overheating, while the pump's compact, panel-mountable footprint (7.02 × 7.32 × 9.89 in / 178 × 186 × 251 mm) makes it easy to integrate into existing equipment, benchtop setups, or OEM systems.
Whether you're pulling vacuum for resin infusion, running a vacuum degassing chamber, or supporting general-purpose lab and industrial vacuum needs, the 2507-A offers oil-free reliability in a lightweight, easy-to-mount package.
Key Features
- Oil-less operation, process air discharge stays free of lubricant contamination, protecting sensitive materials and processes.
- Low-vibration, quieter WOB-L piston design, well suited to noise-sensitive lab and production environments.
- Thermally protected motor, built-in 145 °C ± 5 °C thermal switch helps prevent motor damage from overheating.
- Compact and lightweight, panel-mountable footprint fits easily into existing systems or benchtop setups.
- Versatile vacuum performance, up to 2.32 cfm open flow and 26.6 in-Hg maximum vacuum, ideal for vacuum infusion, degassing, and general lab/industrial vacuum service.

Frequently Asked Questions
What is the maximum vacuum the 2507-A can pull?
The 2507-A reaches a maximum vacuum of 26.6 in-Hg (90.9%) when operated at 60 Hz.
What is the open flow rate of the 2507-A vacuum pump?
At 60 Hz, the 2507-A produces an open flow rate of 2.32 cfm (65.8 L/min). At 15 in-Hg of vacuum, flow drops to 0.98 cfm (27.7 L/min).
Is the 2507-A an oil-less vacuum pump?
Yes. The 2507-A uses an oil-less WOB-L piston design, so the process air and exhaust stay free of lubricant contamination, making it a good fit for applications where clean vacuum is required.
Can the 2507-A be used for vacuum infusion?
Yes. Its combination of oil-free operation, sufficient vacuum depth (26.6 in-Hg), and low-vibration piston design make it well suited to vacuum infusion processes in composites and fiberglass work.
What voltage and frequency does the 2507-A require?
The 2507-A operates on standard 115 V, 60 Hz power and draws a nameplate full-load current of 3.3 A.
What size are the intake and exhaust ports?
Both the intake (Port B) and exhaust (Port E) use 1/4-18 NPT threaded ports.
Does the 2507-A have overheat protection?
Yes. It includes a built-in thermal protection switch that trips at 145 °C ± 5 °C to help prevent motor damage.
What are the dimensions and weight considerations for mounting?
The 2507-A measures 7.02 × 7.32 × 9.89 in (178 × 186 × 251 mm) and is designed with a compact, panel-mountable footprint for easy integration into benchtop or OEM setups.
What is the recommended operating environment for the 2507-A?
The pump is rated for ambient operating temperatures between 10 °C and 40 °C.
