Emsco Unbt Mud Pump Bimetal Liners

The Emsco Unbt Mud Pump Bimetal Liners are designed as interchangeable inserts for the fluid end of mud pumps used in drilling operations. Each liner can be supplied in a steel version fabricated from 4135 alloy steel or in a ceramic version combining zirconia with aluminium oxide. The catalogue lists three liner configurations - a high‑chrome sleeve, a single‑shell steel liner and a zirconia ceramic liner - and includes matching valve and seat components. Suppliers also provide compatible pony‑rod and piston‑rod parts made from heat‑treated alloy steel.

4135 alloy steel is a widely adopted grade for high‑stress pump components, typically heat‑treated to achieve a hardness of 45‑55 HRC and a deep carburised wear surface. Ceramic liners made from zirconia and aluminium oxide are standard where abrasive slurry and elevated temperatures demand superior wear resistance, offering a typical service life of over 2 000 hours. The valve and seat assemblies follow the same forged‑alloy construction, providing consistent performance across the fluid‑end assembly. These specifications align with the standard requirements for both on‑shore and offshore drilling rigs.

Primary customers include drilling service firms and equipment distributors that outfit rotary‑steering rigs. Buyers generally specify the liner type required for their pump model and request a complete fluid‑end kit, including the associated valve, seat and rod components. Trade discussions should cover the supplier’s standard packaging, Incoterms and payment conditions, and a formal purchase order should be issued once the technical data sheet is approved.

Dongying Lake Petroleum Technology Co., Ltd operates from Huanghe Road in Dongying, Shandong, China. Listed as an imported‑tier supplier with a harbour‑level trust rating, the company currently shows a response rate of zero percent, indicating that inquiries may need to be followed up repeatedly. Its product catalogue focuses on mud‑pump fluid‑end parts such as cylinder heads, valve assemblies and the bimetal liners described here. No explicit details on annual output, certifications or minimum order quantities are provided in the listing.

The supplier emphasises the use of strict forging and heat‑treatment procedures to achieve the required mechanical properties of its steel components. Ceramic liners are produced from a blend of zirconia and aluminium oxide, a composition commonly employed for high‑abrasion environments. Prospective buyers should request material test certificates to verify compliance with the described grades. Communication can be initiated through the platform’s contact function to obtain current stock levels and lead‑time estimates.
