Spur gears are a cylindrical shaped toothed component used in kinds of industrial equipment to transfer mechanical motion as well as control speed, power and torque. These customized external spur gears adopt 40Cr alloy steel with heat treatment hardening to HRC50-55 with accuracy grade DIN 8, delivering an excellent balance of core toughness and superior surface wear resistance. Designed exclusively for pump equipment, they deliver outstanding wear resistance and stable meshing performance under continuous operation, effectively reducing noise, improve working efficiency and extending pump service life.

Spur Gear for Pump
Our customized external spur gears are manufactured from premium 40Cr alloy steel and processed to strict DIN 8 standards with complete heat treatment standards to 50-55HRC, perfectly matched to continuous operation of various pumps. Structurally, spur gears adopt straight tooth design parallel to the gear axis, which brings important strengths for pump transmission compared with other gear. They are characterized by stable efficiency and easy installment for pump equipment. Installed on pumps, our spur gears deliver high transmission efficiency that lowers energy consumption for continuous operation, and the straightforward structure simplifies pump maintenance to reduce long-term spare part costs and extend overall life of pump equipment.

Forging
When gears need high performance that needs to withstand high loads, high stress, impact loads or fatigue loads, forgings are suggested to use. Forging allows metal fibers to be continuously distributed along the gear profile, significantly improving root strength and fatigue life.
Turning
This is the process of cutting and shaping solid materials into precise parts. It uses tools like lathes, mills, and drills to remove excess material. Machining transforms a simple block of metal into a finished, functional component.
Gear Cutting
Gear Cutting includes all processes to create gear teeth after rough or fine machining. It shapes teeth to ensure smooth and efficient power transfer for performance, strength and cost efficiency.
Heat Treatment
Gears need to be running with two gears or above two gears, that makes them easy to be worn-out. That’s why most types of gears need to be harden through heat treatment.
ID & OD & Surface Grinding
ID grinding, OD grinding, Surface grinding are all belonging to CNC grinding which are the foundational precision abrasive machining processes used to achieve exceptional dimensional accuracy and surface finishes, especially on hardened materials.
Tooth Grinding
Tooth Grinding are the final processes are applied after heat treatment to correct distortion, improve geometry, and achieve the final surface finish necessary for quiet, efficient power transmission.
