What we support
Product review, application discussion, and overseas communication
Dry screw vacuum pump selection
We start from the working pressure and required volumetric flow rate, then review the available product information and configuration questions for the duty.
Explore dry screw pumps →Application review
Application review can include gas or vapor condition, inlet temperature, liquid carryover, dust, duty cycle, cooling, discharge, and site requirements as needed.
Review applications →Overseas RFQ and export communication
Taizhou Shichang Import and Export Co., Ltd. supports overseas sales, export communication, and international inquiries for the SC Air Power Tech brand.
Start an RFQ review →Evidence and information
Review the information relevant to your decision
The website brings together confirmed product material, application notes, approved project references, and technical guidance. Use the route that best matches the question you are reviewing.
Product information
Review the dry screw vacuum pump selection route, operating-point records, and configuration questions.
View products →Application references
Review the confirmed application directions currently documented on the website.
View applications →Verified project reference
Review a confirmed plastic thermoforming project reference. The page identifies the project delivery context and its evidence boundary.
View project reference →Technical guidance
Use the technical blog to prepare a more useful pump-selection discussion before sending an RFQ.
Read technical articles →How to begin
Start the project discussion with the operating point
You do not need to complete a full technical datasheet before contacting us. The first two inputs are enough to begin; the remaining process conditions can be clarified during follow-up.
Start an RFQ review- 01
Start with the operating point
Send the working pressure and required volumetric flow rate. These two values are enough to start the first RFQ discussion.
- 02
Confirm the process conditions
Gas or vapor, temperature, liquid carryover, dust, duty cycle, cooling, discharge, and site requirements can be confirmed during follow-up as needed.
- 03
Review the available configuration
The final recommendation depends on the confirmed duty and available product information. An existing pump model can be a reference, but not a one-to-one replacement promise.
