Product Core Advantages

Traditional external gear pumps generate large meshing loss, and vane pumps are prone to wear and leakage. In contrast, Hengmeisi QX41-040L12 gear oil pump adopts optimized internal gear profile structure to greatly improve overall performance. Hengmeisi upgrades the internal structure of this gear oil pump to eliminate unilateral pressure load and reduce friction loss. Hengmeisi QX41-040L12 gear oil pump steadily maintains 98% ultra-high volumetric efficiency during long-term operation.

Hengmeisi QX41-040L12 gear oil pump is equipped with an advanced pressure balance design to achieve ultra-low pulsation and smooth operation. The stable working state of Hengmeisi gear oil pump slows down the aging and loss of internal parts effectively. Actual test data proves that the service life of Hengmeisi QX41-040L12 gear oil pump is more than 30% longer than ordinary industrial gear pumps. This advantage greatly reduces equipment replacement frequency and daily maintenance costs for end users.
