UNB600 Mud Pump Herringbone Gear / Gear Ring Product Title

This UNB600 mud pump herringbone gear (also called double helical gear or gear ring) is the core transmission component of the UNB600 double-acting duplex mud pump, which is widely used in oilfield drilling, geological exploration, water well drilling and mining dewatering projects. It is responsible for transmitting power from the motor to the crankshaft, converting rotational motion to drive the pump's reciprocating mechanism, ensuring stable and efficient operation of the mud pump under high-load working conditions.

Manufactured from high-strength alloy steel (42CrMo / 40CrNiMo), this herringbone gear undergoes strict forging, heat treatment (quenching and tempering, carburizing quenching), precision gear hobbing and grinding processes. It features excellent wear resistance, impact resistance and load-bearing capacity, with zero axial thrust design to reduce bearing wear and extend service life. It is a 100% direct replacement for original UNB600 equipment, ensuring perfect fit, smooth transmission and easy installation without modification.

The gear is strictly manufactured according to original UNB600 mud pump drawings, with high precision gear tooth profile and pitch to ensure stable meshing, low noise and high transmission efficiency. The high-quality alloy steel material provides great tensile strength and fatigue resistance, adapting to harsh oilfield working environments. We also provide matching gear shafts and full sets of UNB600 mud pump accessories including crosshead, connecting rod, crankshaft, pump housing, fluid end, valve seat and piston for one-stop procurement. Custom processing based on customer drawings and special material requirements is also available.

The product meets ISO 9001 and API 7K standards, with strict quality inspection including hardness test, flaw detection and dimensional accuracy test. Our monthly supply capacity is 80 sets, and the lead time is 10-25 days after receiving the deposit. It is packed in standard export fumigated wooden crates with rust-proof treatment for safe transportation.
