A China rotary vane vacuum pump manufacturer should connect a specific model to your process duty. Working pressure, pumping demand, gas conditions and operating hours matter more than a general catalog claim. A lower ultimate pressure does not by itself show how quickly a pump will evacuate the chamber under its actual load.
The eight companies below come from the supplied keyword directory and were selected for their rotary vane information. Duplicate brand websites and candidates with insufficient relevant evidence were removed. The order is a practical shortlist rather than a sales ranking or an independent factory audit.
Quick takeaway: Contact DV Vacuum when the inquiry also needs industrial package engineering. Compare exact models from the other candidates using the same pressure, gas, installation and service requirements.

It is suitable for an initial technical inquiry, with factory qualification depending on further product and production evidence. Its role in a manufacturer comparison depends on the product and factory evidence returned for the exact offered pump.
Buying Tips: Request a model catalog, pumping curve, manufacturing entity and final test scope. Confirm who supplies lubricant, filters, seals and repair support in the destination market.
Rotary Vane Pump Configurations
| Configuration | Application Starting Point | Key Questions |
|---|---|---|
| Single-stage oil-sealed | Packaging and compatible general industrial duty | Working pressure, oil management and duty cycle |
| Two-stage oil-sealed | Laboratory and backing service requiring lower ultimate pressure | Stage construction, test conditions and gas ballast |
| Oil-free rotary vane | Compatible suction with an oil-free pumping chamber | Achievable pressure, vane material and wear schedule |
| Integrated package | A pump supplied with protection and other equipment | Inlet accessories, controls and performance boundary |
How to Select a China Rotary Vane Vacuum Pump Manufacturer
1. Define Performance at the Process
Provide chamber volume, evacuation time, working pressure and gas load. Include the inlet pipe route, valves and filters so the supplier can consider connection losses. Request a pumping curve at the actual electrical frequency and an explanation of why the proposed model meets the required duty.
2. Match the Medium and Protection
Describe vapor, dust, temperature, chemicals and possible liquid carryover. Discuss gas ballast, trapping, filtration, exhaust separation and lubricant compatibility. Ask the manufacturer to state the permitted conditions and any additional equipment required to protect the offered pump.
3. Verify Manufacturing Responsibility
A catalog may combine internally produced pumps, distributed brands and replacement products. Confirm the legal manufacturer, assembly site and delivered nameplate. Request evidence for the exact model and its final testing rather than using general factory claims as proof of production responsibility.
4. Agree on Acceptance and Support
Define test conditions, performance criteria, supplied accessories and operating instructions. Obtain lubricant and spare-part identifiers and a maintenance plan appropriate to the process. For repeat supply, record the approved configuration and how later component changes will be communicated.
What Affects Rotary Vane Vacuum Pump Cost?
Compare the complete configuration and the same operating duty across suppliers. The initial equipment quotation should be assessed together with the accessories, utilities and service needed for the actual application.
- Stage count, capacity and required working pressure
- Motor supply, mounting and connection standards
- Inlet traps, filters, gauges and exhaust separation
- Oil, filters, seals and repair availability
- Packing, acceptance documentation and delivery terms
Request a written configuration list, a performance basis and a maintenance schedule. These establish a fair quotation comparison and a practical acceptance reference for delivery.
FAQs – Rotary Vane Vacuum Pump Manufacturers in China
Q1: Is a two-stage pump always better?
A comparable two-stage oil-sealed design generally reaches a lower ultimate pressure, but the correct model depends on working pressure and gas load. Many general industrial duties can use a suitable single-stage pump.
Q2: What belongs in a factory RFQ?
Send the chamber volume, pressure target, evacuation time, gas composition, temperature, operating hours and electrical supply. State accessories, quantity and delivery destination.
Q3: Can a rotary vane pump handle vapor?
Suitability depends on the model and vapor conditions. Ask the manufacturer to review gas ballast, trapping, oil compatibility and exhaust requirements for the actual medium.
Q4: How do I check who manufactures the pump?
Identify the legal entity and production site and request model-specific assembly and test evidence. Confirm whether the offer is internally produced or sourced and who provides its warranty.
Q5: Are InPowerVac and hi-team.cn separate entries?
The supplied materials identify the same company and brand behind both websites. They are counted once in this shortlist.
Q6: Does DV Vacuum offer rotary vane options?
DV Vacuum publishes single-stage and two-stage oil rotary vane pumps. Confirm the exact model, production responsibility, accessories and service scope in the technical offer.
Which Rotary Vane Vacuum Pump Manufacturer Should You Choose?
Include DV Vacuum in an initial technical comparison when the duty needs wider industrial package engineering. Review the other named ranges using the same process data and acceptance requirements. Choose the supplier that can explain the model selection, identify the delivered product and support it through its intended service life.
Send every shortlisted supplier the same process and installation information. Obtain an identified model, supporting data, equipment scope and service plan before placing the order.
