PARTNERSHIP NOTES
Single-stage or two-stage vacuum pump? Choose for the duty
Stage count describes the pump architecture. The right choice still depends on the exact model and application.
PARTNERSHIP NOTES
What to include in an OEM or distributor inquiry
A clear application, market and delivery brief helps both sides define the proposed cooperation and sample evaluation.
BEFORE YOU ASK.
Can I inquire before choosing a model?
Yes. Share the application, target pressure, system volume or equipment details, electrical supply and expected purchasing needs. Mark anything unknown so the candidate models can be discussed step by step.
Is a two-stage pump always the better choice?
Suitability depends on the duty. Within a similar pump technology, consider stage count alongside required pressure, pumping speed, operating duty, dimensions and maintenance. Check the exact model specifications before deciding.
How do I confirm compatibility with my refrigerant and system?
Provide the refrigerant name, process steps and system details. Compatibility must be confirmed in the manufacturer's documentation for the exact model; a refrigeration-tool label or product appearance is insufficient.
Can we discuss OEM, packaging or distribution?
You are welcome to send a cooperation brief. Include the target market, product category, estimated quantities and labeling, packaging or technical requirements. Feasibility and cooperation terms require confirmation by both parties.
What product documents should I request?
Ask for the exact model's data sheet, dimensions, connection information, operating and maintenance instructions, and a list of available destination-market documents. Check document versions and use the final agreed information.
How do I contact this site's business cooperation channel?
Email lituobd@163.com with the product category, application and proposed cooperation. This site introduces factory products through a dedicated business cooperation channel and helps coordinate requirements. Specifications and transaction terms require further confirmation.
