Heavy cement dust, slurry splashing, wide temperature fluctuation (-40~75℃), multi-point distributed lubrication: boom pivots, rotary bearings, S-pipe swing mechanism, mixing shaft, outrigger hinges. Manual lubrication causes inconsistent grease supply and frequent wear failure of core wearing parts.
WDB-M Electric Pump + JPQ1 Distributor | Loader Centralized Lubrication Application Case
Loaders always operate under harsh working conditions with heavy loads, strong vibration and high dust. Key components such as pins, hinge points and bearings are prone to dry wear and damage due to uneven, missing or delayed manual lubrication, resulting in high failure rates, frequent downtime and increased maintenance costs. Our WDB-M electric pump + JPQ1 distributor automatic centralized lubrication system is specially customized for loader operating scenarios, suitable for new machine supporting and equipment upgrading of 5–30 ton loaders.
Excavators work in harsh conditions with heavy vibration, dust and mud. Critical components like boom pins, hinge joints, slewing bearings and traveling parts suffer from dry wear and frequent failures due to traditional manual lubrication's uneven oil supply and missed greasing. The WDS-II Electric Pump + QX-1 Single-line Distributor automatic lubrication system is customized for excavators, suitable for new machine OEM assembly and old equipment retrofit.
WDS-I Electric Lubrication Pump Application Case: Concrete Mixer Truck
Brief Overview Concrete mixer trucks work under harsh outdoor conditions: heavy dust, mud splashes, wide temperature fluctuations, and frequent vibration. Traditional manual greasing causes insufficient lubrication, fast component wear, high maintenance costs and safety risks. Our WDS-I electric lubrication pump delivers fully automatic centralized lubrication for mixer truck chassis, rollers, raceways and hinges.
Motor graders operate in heavy dust, wide temperature fluctuation (-40℃~75℃) & continuous vibration. Manual greasing leads to uneven lubrication, fast wear of blade hinges, wheel bearings and swing joints. Our combined WDS-I electric grease pump + JPQ1-A progressive distributor delivers fully automatic centralized lubrication for graders.
WDB-M Electric Grease Pump | Asphalt Paver Application Pain Points of Asphalt Pavers
Pavers work under extreme conditions: high temperature from hot asphalt, heavy dust, long-time vibration and outdoor exposure. Traditional manual greasing leads to:
- Premature wear of auger bearings, screed hinges and track pivots due to insufficient lubrication
- Safety risks when staff grease components under the machine
- Frequent unexpected shutdowns caused by uneven grease supply
- IP65 fully sealed, working pressure up to 250bar, operating temperature: -40℃ ~ 80℃
- Modular independent pump outlets (1–4 ports), each fitted with pressure gauge & safety relief valve
- Transparent resin oil tank (2L/4L/6L) for direct grease level observation
- Optional built-in programmable controller; compatible with QDV / JPQ1-A progressive distributors
Application Case: WEIDUN Quick Fueling Joints for Bucket Wheel Stacker Reclaimer
Bucket wheel stacker reclaimers operate outdoors under heavy dust conditions and require multiple types of lubricants. Unmarked conventional fittings often lead to lubricant cross-contamination, component failure and frequent unplanned downtime. A thermal power plant upgraded its equipment with WEIDUN color-coded U-end and T-end grease fittings to resolve these problems.
