Need a Circular Vacuum Pump Radiator That Fits?
A circular vacuum pump radiator is a round oil radiator that keeps the sealing and lubricating oil of a vacuum pump at the right temperature. If your pump uses a ring-shaped cooler and the original part is hard to find, we build a 100% custom round radiator to your drawing or sample.
Key Features & Benefits
- Made to your drawing or sample: exact envelope, ports and mounting - no "almost fits".
- Circular / ring-shaped design: matches the original circular vacuum pump cooler geometry.
- Vacuum-brazed aluminum core: strong, leak-free joints.
- 100% pressure tested: every radiator tested before shipment.
- OEM/ODM: your brand, your packaging, from prototype to volume.
Product Specifications

| Maximum working pressure | up to 2.0 MPa |
| Core | Vacuum-brazed aluminum plate-fin |
| Connections | G threads, SAE or custom |
How It Works
- Hot oil from the vacuum pump enters the circular radiator.
- The oil flows through the ring-shaped core, and heat transfers to the fins.
- A fan blows air across the fins (air-cooled) or water flows through adjacent passages (water-cooled).
- The cooled oil returns to the pump, keeping vacuum performance stable.
Applications & Aftermarket
Circular vacuum pump radiators are used on rotary vane, liquid ring and other vacuum pumps in packaging, plastics, medical, food and industrial plants. If your original round cooler is discontinued or hard to source, we manufacture a replacement circular radiator from your drawing or sample - a fast, cost-effective solution.
We also supply cooling for related machines: OEM replacement air compressor aftercoolers & oil coolers, excavator coolers and vacuum pump radiators.
