What drilling fluids are your pistons compatible with?

NBR/PU pistons fit WBM, SBM, OBM and clear water. HNBR pistons additionally support salt water & seawater, ideal for offshore drilling; none of our products are recommended for high-concentration salt water long-term use.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier with broad customization, ODM, and OEM capabilities. It holds ISO9001:2015, ISO45001:2018, and ISO14001 certifications, and reports documented quality, corrective-action, and complaint-handling procedures. Its export share is stated at 71%–90%, with 23 years of export experience, inventory capability, and participation in the Offshore Technology Conference. However, it does not provide 3D software design services, has no available SDK, no overseas warehouse, showroom, agent, or branch, and no valid manufacturing-capacity contract with affiliated subcontractors. No new products were launched in the past year, and only two R&D engineers are reported. Financial records are identified for 2021–2023, but the provided information does not contain sufficient financial performance detail to assess credibility. Customer evidence includes OEM service for well-known brands and repeat-buyer preference of 50%–80%, but no Fortune 500 cooperation.

Supplier typeThe supplier explicitly describes itself as a professional technical supplier and emphasizes learning, innovation, superior products, and technical support. This supports classification as a professional technical supplier rather than a purely trading-oriented entity.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications in both its sustainability and management-system information. These stated certifications provide explicit evidence of formal quality, occupational health and safety, and environmental management systems.

After-Sales capabilityThe supplier states that it provides pre-sales and after-sales technical support, while documented procedures and records exist for corrective and preventive actions and customer complaints. These statements support an established after-sales and issue-resolution process.

R&D capabilityThe supplier has two R&D engineers and offers ODM services, but it does not provide an SDK, did not launch new products in the past year, and does not offer 3D software design services. The evidence shows some development capability but also explicit limitations in recent innovation output and technical-service scope.

Production capacityThe supplier reports in-stock service capability, 23 years of export activity, an export share of 71%–90%, and proximity to Qingdao Port. However, it has no valid manufacturing-capacity contract with affiliated subcontractors and lacks overseas warehouses, branches, and agents, so production and international fulfillment capability cannot be rated as clearly strong overall.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, flexible customization, and ODM services. This is direct evidence of broad customization capability, although 3D software design services are not provided.

Client casesThe supplier reports participation in the Offshore Technology Conference, OEM service for well-known brands, and repeat-buyer preference of 50%–80%. However, it reports no cooperation with Fortune 500 companies and provides no specific customer names or case details, so the evidence is positive but limited.

Product Q&A

Q:Are your mud pump pistons interchangeable with Mission/Green Duo pumps?

Yes. Our full series pistons are fully interchangeable with Mission, Green Duo, Blue Lightning and other mainstream international mud pump brands, sizes cover 3"(75mm)-8"(200mm) A/B/K/L series.

Q:What rubber materials do you offer for piston sleeves?

We supply 4 types of rubber formulas: NBR, HNBR, single hardness polyurethane, dual duro polyurethane. Imported USA raw material and domestic high-quality raw material are both optional.

Q:What is the maximum working temperature and pressure of your pistons?

NBR & single PU piston: Max 120 C, 5000PSI. HNBR & dual duro PU piston: Max 150 C, 7500PSI, suitable for high temp & high pressure deep wells.

Q:What is the difference between assembled piston and bonded piston?

Assembled type has replaceable rubber insert, only change worn sleeve to cut maintenance cost. Bonded vulcanized type integrates rubber and steel hub, avoids mud penetration, longer service life for continuous heavy work.

Q:Can you accept OEM & customized non-API pistons?

Yes. We support OEM private label, custom size, special rubber hardness and non-API design. Both API standard and customized solutions are available for onshore & offshore drilling projects.
