Product Overview

This single-cylinder air compressor (air pump) matches Weichai WP6/WP10/WP12 engines, it i s the core air supply component for air brake system of wheel loaders and heavy trucks. It adopts integrated cast iron heat dissipation housing with original flange direct-mount structure, equipped with original oil-air ports and red dust-proof valve cap. Driven directly by engine gear shaft, it
continuously compresses air to supply high-pressure air for vehicle braking, air horn and clutch. Multi-layer heat sink ribs on housing realize excellent heat dissipation to avoid overheating cylinder seizure under high temperature working conditions. Oil & high temperature resistant sealing components prevent air leakage and pressure loss. Produced strictly per Weichai original drawing, flange holes and drive shaft size fully match original parts for plug-and-play replacement. Compatible with XCMG, Lingong, Lovol, Shantui all series loaders with Weichai power. Suitable for domestic repair shop maintenance, used machinery refurbishment and complete machine export, supported by Qinyang Hengsheng 7/24 cross-border remote after-sales service system.

Core Product Parameters

Core Product Features

• Original flange mold design, plug-and-play without modification
  4-hole triangular flange, drive shaft and oil/water ports fully match Weichai WP6/WP10/WP12 engines, no drilling or pipe modification required. Single operator finish replacement within 10 minutes, ideal for fast assembly during loader refurbishment.
• Thick cast iron cooling cylinder, anti-seize under high temperature
  Integral cast ring heat sink cooperates with engine water circulation for fast heat dissipation under continuous heavy load. Avoid cylinder overheating and piston seizure during summer mine operation, lower risk of brake failure.
• Multi-layer oil-resistant sealing, long-term pressure retention without leakage
  Built-in multi-layer fluororubber oil seals and high-temperature gaskets block oil seepage and air pressure loss. Stable sealing performance under long bumpy & temperature cycle working conditions, eliminate low air pressure and soft brake failure.
• Equipped with dust-proof valve cap for harsh construction sites
  Standard red dust-proof cap for air outlet pressure valve, prevent mud and gravel from blocking valve port, avoid slow air pressure build-up. Service life increased by 40% in dusty overseas mining sites.
• Independent shockproof packaging for sea export
  Each unit packed with foam liner in hard carton, anti-collision & anti-rust for cast iron housing. Bilingual model marking for easy warehouse sorting and customs clearance, well protected for long-distance container sea transportation.

Typical Application Scenarios

• Level 1 Machine Inspection: Full overhaul of used XCMG/Lingong/Lovol loaders before shipment;
  Level 2 Brake Air Supply: Uniformly replace old air pumps with this original compressor to fix air leakage, slow pressure build-up and overheating failure. Covered by 3-month core spare parts warranty for overseas buyers.
• Level 1 Stock Layer: Repair shops stock mainstream WP10/WP12 air compressors;
  Level 2 Maintenance Layer: Fast replacement for low brake pressure, no air output and oil leakage faults, one-stop supply matching thermostat, fuel heater, loader headlight and other Weichai maintenance parts.
• Level 1 Domestic Warehouse: Bulk stock at Qinyang Hengsheng spare parts warehouse;
  Level 2 SeaTransportation: Carton packing with independent boxes, moisture-proof, anti-collision & anti-rust;
  Level 3 Overseas Maintenance Station: Bulk replacement for mining fleets in Africa, Middle East & Southeast Asia; Advantage: Original direct installation without modification, bilingual installation guide, local workers finish replacement independently, supported by 7/24 multilingual remote video technical support.

Product Benefits

• Original matching fast air pressure build-up, ensure brake system safety
  Stable compression efficiency reaches standard brake pressure quickly after startup, sensitive brake response under heavy load climbing & downhill operation, prevent safety accidents caused by insufficient air pressure, improve mine construction safety.
• High-efficiency water cooling, sharply reduce high-temperature failure return rate
  Ring heat sink maintains stable temperature, avoid piston seizure under long summer high-temperature operation.
  Compressor failure return rate reduced by 65% in tropical overseas mines, cut equipment downtime loss.
• Long-term sealing anti oil & air leakage, reduce vehicle operation cost
  Anti-aging sealing parts eliminate oil seepage and air pressure loss, cut labor & material cost from frequent oil refilling and leakage maintenance, extend overall service life of brake system parts.
• Export-standard packaging, ease cross-border after-sales pressure
  Full pressure test before delivery with ultra-low factory failure rate. Independent shockproof package avoids damage during sea transport. Original flange no modification needed, local workers handle replacement without professional technicians, greatly cut on-site service & return logistics cost.
