Backed by LEKEFU’s strict quality control and stable production capacity, this pump offers a cost-effective, long-lasting solution for your heavy-duty hydraulic needs.

· Bi-Rotation Capability: Operates efficiently in both clockwise and counterclockwise directions, eliminating the need for pump-specific rotation matching and simplifying system design.

· High Efficiency & Durability: Precision-machined internal components and high-quality materials minimize internal leakage, delivering high volumetric efficiency and low noise even under continuous high-pressure operation.

· Wide Displacement Coverage: Multiple displacement options (30–100 series) allow precise matching to different vehicle power take-off (PTO) configurations and hydraulic system flow demands.

· Robust Construction: Heavy-duty cast iron housing with anti-corrosion coating ensures resistance to vibration, shock, and harsh operating environments, extending service life.

· Easy Integration: Standard ISO 4H mounting and spline design enables direct compatibility with most truck PTO units, reducing installation complexity and downtime.

Q: What types of power take-off (PTO) and hydraulic pumps do you produce?

We specialize in manufacturing a full range of vehicle-specific PTOs and hydraulic pumps, including gear pumps, piston pumps. We also offer customized models to meet the power and flow requirements of different dump truck models (e.g., heavy-duty, medium-duty, and small-duty dump trucks).

Q: Are your PTOs and hydraulic pumps compatible with global dump truck brands?

Yes. Our products are compatible with mainstream dump truck brands worldwide, such as Isuzu, Eaton, Kamaz, Scania and Volvo. We provide standard models for well-known brand OEM/ODM needs, and we can also adjust product parameters (shaft type, flow, pressure) to match non-standard dump truck models through custom development.

Q: What quality certifications do your products hold?

All our key products have obtained IATF 16949:2016 certification (automotive industry standard). Each product undergoes 100% quality inspection (including pressure resistance, wear resistance, and durability testing) before leaving the factory to ensure stable performance.

Q: What is your production capacity and delivery time?

The annual production of power take-off and various pump products exceeds 200,000 units. For standard models: Stock products: Delivery within 3-5 working days after payment; Custom models: Delivery within 15-25 working days after confirming the order and design drawings.

Q: Can you customize PTOs and hydraulic pumps according to our specific requirements?

Yes. We have a professional R&D team (10+ engineers) to support full customization: Customizable content: Shaft type, flow, pressure, size, logo, and packaging; Custom process: Provide product drawings/parameters , Confirm design , Sample production , Mass production, Delivery; MOQ for custom orders: Negotiable.

Q: Which brands of tank trucks and power take-offs (PTO) is this air compressor compatible with?

It fits mainstream bulk powder tank trucks such as CIMC, Tongya, Juntong and Yangjia. It matches standard PTOs for Howo, FAW, Mercedes-Benz, Volvo and other trucks. Any power take-off device with torque ≥500 N·m and power of 40~50 kW can be directly installed. Matching PTO accessories are also available.

Q: How long should the unit cool down before reuse after 120 minutes of continuous full-load discharging?

After 120 minutes of continuous full-load operation, shut down for 30~60 minutes to allow the crankcase to cool before resuming discharging. If the ambient temperature exceeds 35°C, continuous operation shall not exceed 90 minutes. Allow the unit to cool down to ambient temperature before reuse to extend service life.

Q: What is the standard export packaging? Can custom export wooden cases be supplied?

Standard packaging consists of moisture-proof cartons plus pallets. Fumigated solid wooden cases are provided as standard for export. Thickened shockproof wooden cases can be customized according to sea or land transport requirements to meet protection standards for long-distance ocean shipping.

Q: How are delivery lead times categorized, and what is the fastest shipping schedule?

In-stock items ship within 7 days. Regular bulk orders take 10–15 days. Large customized orders require 20–30 days. Models with sufficient inventory can be prioritized for expedited production.

Q: What basic routine maintenance is required for the air compressor, and what are the maintenance intervals?

① Check the crankcase oil level daily; ② Clean or replace the air intake filter every 100~200 operating hours; ③ Inspect wear of internal self-lubricating sealing strips every 1500~2000 operating hours and replace consumables as needed.

Q: Is OEM / private labeling service available?

OEM service, neutral packaging and customer brand private labeling are supported. Modifications to machine nameplates and printed LOGOs on outer packages are available. Please contact our sales specialist to discuss customized requirements.

Q: What causes material blockage and insufficient air flow of the air compressor?

Three common causes: ① Clogged air intake filter leading to insufficient air intake; ② Air compressor speed fails to reach operating speed; ③ Faulty valves on discharge pipelines, or air leakage in pipelines/tanks. Troubleshoot the filter, PTO rotating speed, and pipeline/tank sealing in sequence to resolve the issue.

Q: Can CE test reports and other customs clearance documents for export be provided?

The complete unit holds CE certification. After order placement, we can provide full sets of customs clearance documents free of charge, including the CE certificate, product specification sheet, packing list and commercial invoice, to satisfy customs declaration requirements for Europe, America, Southeast Asia and other regions.
