Vietnam’s industrial equipment market is currently facing the problem of counterfeit diaphragm pumps and products of unclear origin. Thai Khuong Engineering and Trading Co., Ltd. (Thái Khương Pumps), as the officially authorized distributor appointed by Warren Rupp, Inc. (manufacturer of Sandpiper pumps) in Vietnam, publishes this notice to establish order and transparency in the market and to protect the brand and the interests of enterprises.
This notice affirms that in Vietnam, Thái Khương Pumps and its network of authorized distribution partners are the entities with full legal authority and capacity to supply genuine Sandpiper air-operated diaphragm pumps.

1. Sandpiper’s Global Authorized Distribution Policy
Warren Rupp, Inc., the inventor of the air-operated double diaphragm pump (AODD) since 1965, enforces a policy of designating a single authorized distributor in each country. This policy aims to:
- Ensure product quality: All supplied products are controlled through a single supply chain, preventing counterfeit and substandard goods.
- Standardize technical services: Technical teams are trained directly by the manufacturer, with the competence to advise on installation and handle troubleshooting to rigorous standards.
- Protect the warranty policy: Products distributed through authorized channels are eligible for Sandpiper’s 5-year global warranty.
In Vietnam, Thái Khương Pumps is the entity selected to implement this policy.

2. Thái Khương Pumps and Its Partner Network
To deliver genuine products and services to enterprises across Vietnam, Thái Khương Pumps has established a network of distribution partners selected and trained to defined standards.
- Thái Khương Pumps: As the master representative, responsible for importing, warehousing, warranty services, and market development.
- Authorized Partners: Commercial and technical entities operating under the supervision and support of Thái Khương Pumps, ensuring all supplied products are genuine and accompanied by complete, valid documentation.
Therefore, any entity or organization not belonging to the Thái Khương Pumps distribution network that claims the ability to supply new, genuine Sandpiper pumps is making claims without basis and not recognized by Warren Rupp, Inc.
3. Legal and Financial Risks from Unauthorized Supply Sources
Purchasing products from unofficial channels carries serious risks:
- Invoice validity: Financial invoices for products of unclear origin risk being rejected by tax authorities and not recognized as valid input costs, resulting in tax reassessment and penalties.
- Document legality: Documents such as Certificates of Origin (CO) and Quality Certificates (CQ) from unofficial sources carry no legal standing. Using such documents may be treated as commercial fraud, affecting the enterprise’s reputation and quality management certifications (ISO).
4. Mandatory Verification Process: Protecting Your Enterprise
We recommend all enterprises carry out the following two-step verification process before making a purchase decision:
- Step 1: Verify the Supplier: Visit Sandpiper’s global website and use the “Find a Distributor” tool. For the Vietnam market, the results display the information of Thái Khương Pumps. This serves as evidence of the legitimate distribution channel.
- Step 2: Verify the Product: Use the manufacturer’s lookup tool with the serial number on the pump label to check the product’s detailed information.
