Why These Resources

Built on Real Manufacturing Data

Manufacturer-Sourced

Every spec, material table and pressure rating comes from SINOR's own engineering and production data — not recycled marketing copy.

Practical Selection Tools

Media-to-material mapping and model naming rules you can use directly when specifying a pump.

OEM Compatibility

Cross-reference tables cover NETZSCH, MONO, SEEPEX and ALLWEILER models for confident replacement.

Frequently Asked Questions

What is the MOQ for your products?
MOQ varies by product. For standard pumps, MOQ starts from 1 unit. For custom parts, minimum quantities may apply. Contact us for details.
What stator materials do you offer?
We offer NBR (Nitrile), EPDM, FKM (Viton), and HNBR. NBR is best for oils and fuels, EPDM for water and chemicals, FKM for high-temperature applications, and HNBR for extreme wear conditions.
Do you provide samples before bulk order?
Yes, we offer samples for material and dimensional approval. Sample production takes 3-7 working days. Shipping costs may apply for international samples.
What is the typical lead time?
Standard production takes 15-25 working days. Rush orders can be expedited to 10-12 working days. Shipping time depends on destination and shipping method.
Can I customize pump specifications?
Absolutely. We offer full custom manufacturing: special stator geometries, custom rotor coatings (tungsten carbide, ceramic), non-standard flanges, and special alloy construction.
What certifications do your products carry?
SINOR is ISO 9001 certified, recognized as a National High-tech Enterprise, and holds AAA credit rating. We also hold multiple patents in pump technology.
Do you provide OEM/ODM service?
Yes, we offer full OEM and ODM services. We can manufacture to your specifications, including custom branding, special materials, and unique design requirements.
How do I select the right pump for my application?
Key factors include: flow rate (m³/h), pressure (bar), media viscosity, temperature, solid content, and material compatibility. Contact our technical team for free selection assistance.
What payment methods do you accept?
We accept T/T (wire transfer) and L/C. Flexible payment terms available for long-term partners.
Can I visit your factory?
Yes, we welcome factory visits. Our facility is located in Hengyang, Hunan, with our sales office in Guangzhou. Contact us to schedule a tour.
