3. Buyer Guide for Imports to Mali
Step 1: Chassis & Specification Selection
Choose Euro II or Euro III diesel engines due to local fuel quality considerations in Mali.
Select appropriate tank capacity based on operating street width:
Compact 4x2 (6,000–8,000L): For tight urban residential streets in Bamako.
Heavy-Duty 6x4 (10,000–14,000L): For major municipal drainage networks and industrial septic pumping.
Step 2: Customization & Accessories
Request high-durability high-pressure jetting nozzles (bomb nozzles, rotary nozzles) for grease and silt clearing.
Specify extra-length suction hoses ( 20m–30m total) for deep septic pits.
Step 3: Shipping & Logistics to Mali
Sea Freight Route: Ocean shipment via RORO (Roll-on/Roll-off) or Flat Rack container from Chinese ports (Shanghai/Qingdao/Tianjin) to Port of Dakar (Senegal) or Port of Abidjan (Cote d'Ivoire).
Overland Transport: Transit by heavy trailer/trucking route from Dakar/Abidjan across borders directly to Bamako, Mali.
4. Maintenance Guide
Daily Maintenance (Before & After Duty)
Check Oil Levels: Check oil levels in both the high-pressure jetting pump and the vacuum pump before engaging PTO.
Water Tank Inspection: Fill the jetting tank with clean water only. Never run the high-pressure pump dry.
Flush Vacuum Lines: Clean the suction hose and secondary spill valve after pumping fecal sludge to prevent clogging and valve corrosion.
Weekly Maintenance
Filter Cleaning: Clean the inline water inlet filter for the high-pressure pump.
Grease Points: Lubricate all hydraulic cylinder pivot points, rear door hinges, and high-pressure hose reel bearings.
Four-Way Valve Check: Check air seals on the 4-way reversing valve on the vacuum suction line.
Monthly / Periodic Maintenance
Pump Oil Change: Change oil in the vacuum pump and high-pressure plunger pump after the first 50 operating hours, then every 300 operating hours.
Tank Desalination & Cleaning: Flush internal sludge tank walls to prevent acidic corrosion from fecal matter buildup.
Key Technical & Operational Differences
Feature / Aspect
Standard Fecal Suction Truck
Combined Fecal Suction Jetting Truck
Primary Function
Pure vacuum pumping and suction of liquid sludge, wastewater, and septage.
Dual function: High-pressure water pipe unblocking/cleaning PLUS vacuum suction.
Tank Structure
Single compartment for holding pumped waste/sewage.
Split dual compartments: One tank for clean water (jetting) and one for sludge/sewage (suction).
Clogged sewer lines, municipal underground pipes, grease traps, heavy desilting, combined pipe flushing & sludge removal.
How different fecal suction truck and fecal suction jetting truck
1. Standard Fecal Suction Truck
A standard fecal suction truck relies solely on negative vacuum pressure generated by a vacuum pump (such as a rotary vane or water-ring pump).
How it works: The vacuum pump creates a vacuum inside the sealed tank, atmospheric pressure forces liquid waste and fecal sludge up through the hose into the tank.
Best used for: Direct extraction of liquid sewage, septic tank maintenance, and waste transport where pipes are not clogged or requiring water flushing.
Limitation: It cannot unblock pipes clogged with hardened silt, grease, sand, or debris because it lacks a high-pressure water system.
2. Combined Fecal Suction Jetting Truck
A combined unit (often referred to as a Jetting & Vacuum Truck or Sewer Cleaner Truck) combines two systems onto a single chassis, eliminating the need for two separate trucks on a job site.
How it works:
Jetting Mode: The high-pressure water pump feeds clean water through a specialized nozzle on a long hose. The high-pressure water streams break up blockages, grease, hardened mud, and scale inside underground pipes while flushing the debris back toward the manhole.
Suction Mode: The vacuum pump simultaneously sucks the broken-up sludge, water, and debris into the sewage tank.
Best used for: Comprehensive municipal drainage maintenance, clearing blocked main sewer pipes, street culverts, and heavy industrial sludge cleaning.
Advantage: Saves manpower and equipment investment by completing flushing, unblocking, suction, and transport in a single pass.
5. Frequently Asked Questions (FAQ)
Q1: What is the main benefit of a combined jetting and fecal suction truck vs. a standard vacuum truck?
A: A combined truck performs two critical jobs in one vehicle: high-pressure jetting breaks up hardened sludge, grease, and blockages in sewer pipes, while the vacuum system simultaneously suctions out wastewater, mud, and fecal matter. This eliminates the need for two separate trucks on a job site.
Q2: Is the truck suitable for Mali’s climate and road conditions?
A: Yes. CLW trucks exported to Mali feature tropicalized cooling radiators, heavy-duty leaf spring suspensions, elevated ground clearance, and robust Euro II/III diesel engines designed to handle local ambient heat and diesel fuel grades.
Q3: What engine options are available for export to Mali?
A: We primarily offer DONGFENG, SINOTRUK HOWO, and ISUZU chassis equipped with Cummins, Weichai, or Yuchai engines. Euro II or Euro III mechanical engines are recommended for ease of local repair and fuel compatibility.
Q4: How long does it take to suck a full tank of sewage?
A: Depending on the depth and fluid viscosity, a standard 8,000-liter suction operation with a WEILONG or water-ring vacuum pump takes approximately 4 to 6 minutes at standard working RPM.
Q5: Can the high-pressure jetting pump and vacuum pump work at the same time?
A: Yes, the system can be configured with a split-shaft Power Take-Off (PTO) allowing simultaneous operation of both the high-pressure water pump and vacuum pump when clearing clogged pipes.
Q6: How is the heavy sludge discharged from the tank?
A: The rear door opens hydraulically, and the entire tank lifts via hydraulic cylinders (dump truck style), allowing thick sludge, stones, and heavy silt to slide out easily.
Q7: What spare parts should we order alongside the truck for use in West Africa?
A: We recommend ordering a 1-year spare parts package that includes: jetting nozzles, vacuum pump vanes/seals, high-pressure hose sections, oil seals, suction hose couplings, and air/oil filters.
Q8: What is the delivery lead time from factory production to shipping?
A: Standard manufacturing lead time at our Suizhou factory is 15 to 25 working days. Ocean transit from China to West African ports (Dakar/Abidjan) typically takes 35 to 45 days.
Q9: Does CLW provide operation manuals and technical support?
A: Yes, every export unit includes complete English operation manuals, hydraulic/electrical schematic diagrams, and video tutorials. Online technical guidance is available via WhatsApp and video calls.
Q10: How can I contact CLW Automobile Group for direct factory pricing?
A: You can reach the official export division directly:
