Power Steering Vane Pump WG97254710161688

The OE part number is WG97254710161688. This Power Steering Pump (Vane Pump Type) is the core hydraulic power supply component of heavy‑duty truck steering system. It continuously outputs stable hydraulic pressure to provide power assistance for the steering gear, effectively reducing steering resistance and realizing lightweight, flexible and sensitive steering operation for drivers. It effectively solves common steering faults caused by aging and wear of old pumps, such as heavy steering at low speed, insufficient steering power, pump body oil seepage, abnormal operating noise and unstable hydraulic pressure output. It adopts high‑precision integral vane pump structure, high‑strength aluminum alloy pump body and wear‑resistant internal rotor and blade assembly, matched with multi‑layer high‑tightness sealing components. It maintains stable flow rate and constant pressure output during long‑term engine operation and frequent steering actions, avoiding pressure fluctuation and power assistance failure. Standard oil inlet and outlet interfaces as well as mounting hole positions strictly follow OE dimensions, supporting direct plug‑and‑play installation and keeping stable working condition under long‑distance transportation and bumpy road vibration.

① Applicable vehicle models
Suitable for Sinotruk HOWO series heavy trucks, including 371HP and 380HP logistics tractors, engineering dump trucks and long‑haul transport vehicles perfectly matched with WP12 engine models. Widely used for vehicle daily maintenance, fleet overhaul and spare parts stocking projects.
② Product advantages
• High‑strength aluminum alloy pump body, lightweight, high heat dissipation, anti‑deformation and durable for long‑term operation.
• Precision vane and rotor matching, stable hydraulic output, uniform flow rate, no lag in steering response.
• High‑wear‑resistance internal moving parts, effectively resisting fatigue loss caused by high‑speed continuous operation.
• Multi‑layer imported sealing structure, excellent oil resistance and high temperature resistance, effectively preventing pump body seepage and leakage.
• Strict factory pressure test and noise detection for each unit, stable performance and low noise operation.
• 100% consistent with original installation size, direct replacement without modification, saving maintenance time and cost.

The pump body adopts high‑precision cast aluminum alloy, with light weight, high structural strength and excellent heat dissipation performance, capable of enduring long‑term high‑pressure hydraulic operation and high‑temperature working environment. Internal rotor and vanes are made of high‑wear‑resistant alloy steel after precision finishing and quenching treatment, featuring low friction coefficient and stable operating precision, effectively resisting wear and fatigue loss caused by continuous high‑speed rotation. Multi‑layer sealing components adopt high‑quality oil‑resistant and high‑temperature resistant rubber materials, with outstanding anti‑aging performance, preventing internal pressure leakage and external oil seepage. The built‑in pressure regulating valve assembly maintains stable pressure output, avoiding excessive or insufficient hydraulic pressure. The whole unit has outstanding adaptability to heavy‑truck harsh working conditions, resisting erosion of high‑temperature hydraulic oil and long‑term chassis vibration.

The aluminum pump body surface adopts anti‑oxidation sandblasting and anti‑corrosion coating treatment, effectively isolating erosion from dust, moisture and muddy water to prevent surface oxidation and corrosion. The oil port thread is precision machined and anti‑rust treated to ensure tight connection with hydraulic pipeline and eliminate interface oil leakage. The internal hydraulic oil channel is finely polished to reduce oil flow resistance, ensure smooth oil circulation and sensitive steering response. The surface of internal moving parts is coated with high‑temperature resistant anti‑wear lubricating grease to reduce operating friction and extend service life. All assembly surfaces are precisely deburred to ensure perfect fitting and stable operation.

Aluminum alloy pump body casting, internal precision parts processing and sealing assembly are completed by advanced fully automatic CNC production equipment. Core processing procedures are finished in a constant‑temperature dust‑free workshop to eliminate internal casting stress of the workpiece and avoid later deformation and pressure instability during vehicle operation. Key indicators such as overall dimension tolerance, hydraulic output pressure, flow stability, sealing performance and operating noise are inspected piece by piece with professional precision testing equipment. All finished products pass 100% full inspection before delivery, covering appearance defect detection, static and dynamic hydraulic pressure test, full‑cycle operation fatigue test and high‑temperature durability test. Each batch of goods is screened per OEM standards to fully meet heavy‑load operation and long‑service‑life requirements of HOWO heavy truck steering hydraulic system.

We are equipped with professional aluminum alloy casting production lines and complete hydraulic pump performance testing equipment, with mature standardized stable production processes.
