FAQ
What is the main advantage of GPE Metal Liners over conventional liners?
GPE liners are made from high-chromium alloy steel, offering superior hardness, corrosion resistance, and longer wear life in abrasive drilling muds.
Are the liners compatible with other pump brands?
Yes, GPE liners are fully compatible with major OEM pumps like EMSCO, Gardner Denver, National, and BOMCO.
Can the liner surface be customized?
Yes, surface options include chrome plating, tungsten carbide coating, or ceramic composite finish for specific drilling conditions.
How often should the liner be replaced?
Replacement cycles depend on drilling mud composition, typically every 800–1,200 hours of operation.
Does GPE provide liner-piston matched sets?
Yes. GPE offers liner-piston matched kits to optimize sealing performance and extend service life.
