The Diesel-Engine Driven Self-Priming Drainage Pump Set is a mobile emergency drainage unit with diesel direct drive, high-mobility trailer chassis, and self-priming pump, featuring one-touch control and large-passage anti-clogging impeller for 20-8500 m³/h flow and 8-80 m head operation.
Resolves critical challenges of conventional emergency drainage: grid-dependent delayed start-up, cumbersome relocation, clogging by large particles/long fibers, and difficult off-grid maintenance.
Suitable for urban flood response, municipal repair, construction dewatering, agricultural irrigation, and industrial off-grid backup requiring 30-minute deployment, 5-minute self-priming, 24-hour continuous operation, and transfer of solids ≤80% pump outlet diameter or fibers ≤300mm.
Extended Service Life: Heavy-duty diesel engine + wear-resistant self-priming pump body + heavy trailer chassis resist impact & fatigue. Design lifespan ≥10 years—over 30% longer than standard mobile electric pumps.
Significant Energy Savings: Diesel direct drive eliminates power conversion losses. Combined with high-efficiency self-priming hydraulic model, rated fuel consumption ≤220 g/kW·h, reducing comprehensive energy consumption by 15%–20% vs. “generator + electric pump” emergency solutions.
Lower Maintenance Costs: Modular quick-install design + top inspection ports enable routine maintenance without special tools. One technician completes filter/seal/belt replacement within 1 hour, reducing labor costs by 45%.
Lightweight & Compact Design: High-strength steel trailer + integrated layout reduces overall weight by ~15% for equivalent flow ratings, lowering towing vehicle requirements & relocation transport costs.
Faster Installation: Pre-installed coupling interfaces + adjustable support legs + quick-connect piping enable positioning → pipe connection → startup within 30 minutes, compressing deployment cycle by 60%.

Installation Guidelines
1.Park trailer on solid, level ground. Deploy hydraulic legs & level unit. Ensure pump shaft horizontal deviation ≤2 mm/m to prevent vibration transmission.
2.Connect inlet/outlet with large-diameter flexible hoses. Rigid pipe direct connection is prohibited. Recommend installing foot valve + filter at inlet to prevent large-particle clogging.
3.Equip diesel exhaust system with silencer + rain cap. Route exhaust outlet to safe area to prevent fume recirculation.
4.Before initial startup, check engine oil/coolant/fuel levels. Manually rotate shaft to confirm smooth operation. Open vent valve to prime pump, then close.
Commissioning Process: Vent fuel system → Manual shaft rotation → Jog test for direction → One-key start for self-priming (≤5 min) → Slowly open discharge valve to rated duty → Record RPM/pressure/vibration/exhaust data → Acceptance.

Q1: How does the self-priming pump achieve ≤5-minute rapid priming?
Features gas-liquid mixing self-priming structure + optimized pump chamber volume. After initial priming, diesel start creates vacuum within 30 seconds. Tested: ≤5 minutes to complete priming & reach rated duty.
Q2: How does the trailer chassis adapt to complex off-road conditions?
High ground clearance (≥300 mm) + heavy leaf spring suspension + off-road tires, combined with adjustable legs & towing frame, ensuring stable parking & relocation on muddy/gravel/slope terrain.
Q3: How to prevent pump clogging with large particles/long fibers?
Self-priming pump features large-passage impeller + non-clogging volute design. Minimum flow area ≥80% of outlet diameter. With inlet filter, tested Φ100mm solids/300mm fibers pass smoothly.
Q4: How to ensure diesel reliability during 24-hour continuous operation?
Standard large-capacity fuel tank (≥8-hour range) + forced water-cooling system + three-stage protection (oil/air/fuel filters). Supports refueling & filter replacement without shutdown, ensuring 24h continuous operation.
Q5: What preparations are needed for startup in extreme cold (<-15℃)?
Standard water-jacket preheating + low-temp battery guarantees startup within 3 attempts at -15℃. For <-20℃, add fuel heater + intake preheating module, and use -35# low-temperature diesel.
