API 89mm Positive Displacement Motor 7lz-89-3.4

Yes. We offer full customization of the mud motor to meet your specific needs. Our engineering team can adjust the motor's specifications (length, power section, connection type, elastomer material, etc.) to suit different mud types, torque requirements, or well profiles. Essentially, we can modify the design for higher torque, different flow rates, higher temperature tolerance, or even special thread connections. With our in-house R&D and manufacturing, we accommodate custom orders efficiently.

We accept a variety of international payment terms to facilitate smooth transactions. Common options include Telegraphic Transfer (T/T), Letter of Credit (L/C), as well as others like D/P or D/A. For example, we often work with a 30% T/T advance deposit and 70% balance before shipment, but we are open to negotiation based on order size and customer credit. We can also accommodate Western Union or other e-payment for smaller orders if needed. All payment terms will be clearly agreed upon in the c

Additionally, we can supply a Certificate of Origin and any required customs clearance documents (e.g. CNPC approval letter, embassy certifications) if your country or project need

Routine maintenance is very important to extend the mud motor's life. Under proper use, a mud motor can run for approximately 100 to 200 hours before needing routine maintenance (such as inspection and overhaul). We recommend inspecting the motor's power section and bearing assembly after each major job or when approaching ~150 hours of operation. Maintenance involves disassembling the motor to clean and check the rotor, stator, bearings, and seals, and replacing any worn parts (like the stator

We stand behind the quality of our mud motors. 7LZ89-3.4 Mud Motor comes with a comprehensive warranty that covers manufacturing defects and premature failures. Typically, we offer a 10-month warranty from the date of dispatch, which also equates to a certain number of operational hours (for example, net drilling of 100 hours within 10 months is guaranteed). This means if the motor fails due to a material or workmanship issue within the warranty period (under normal operating conditions and main
