Selection Guide

For urban waterlogging with water depth < 2m and large flooded area → choose our 500m³/h model for rapid drawdown

For river dewatering with lift height > 15m → we recommend pairing with a higher-pressure hydraulic power unit (consult our engineers for matching)

For construction site dewatering with debris-laden water → confirm that solids passing capacity (≤30mm) meets your site conditions

Applications

Urban flood control & waterlogging emergency drainage

River and canal dewatering

Tunnel and underground space water removal

Construction site dewatering

Emergency disaster rescue operations

Agricultural irrigation and drainage support

FAQ

Q1:What is the minimum water level required for this pump to operate effectively?

A: Our hydraulic axial flow pump can operate at a minimum submergence depth of 200mm, which is critical for urban waterlogging scenarios where water depth is often shallow (typically 300-500mm on roads). Traditional centrifugal pumps require at least 500mm submergence and will cavitate in shallow conditions.

Q2: What hydraulic power unit (HPU) specifications do I need to drive this pump?

A: We recommend an HPU with flow rate of 40–100 Lpm and operating pressure of 160–200 bar. If you already have an existing HPU on your emergency vehicle, send us your HPU specs and we will verify compatibility. For customers without an HPU, we offer matching power unit packages.

Q3: How quickly can the pump be deployed from truck arrival to full operation?

A: Two workers can complete connection and deployment within 5–8 minutes. The pump weighs approximately 45kg, requires no lifting equipment, and uses quick-release hydraulic couplings.

Q4: What is the typical maintenance interval and what parts wear out most frequently?

A: Under normal operating conditions (clean water or low-sediment water), recommended maintenance every 500 operating hours. The impeller and wear ring are the primary wear components. We keep these spare parts in stock and can ship within 24 hours for emergency repairs.

Q5: Can this pump run dry for short periods?

A: No. The hydraulic drive motor can run continuously, but the pump end requires water for lubrication and cooling of the mechanical seal. Running dry for more than 30 seconds will damage the seal. We include a dry-run protection sensor as an optional add-on.

Project Experience

1. Inner Mongolia Emergency Management Bureau – Municipal Flood Control Drainage (2025)

Scenario: Urban waterlogging after heavy rainfall, multiple low-lying roads submerged, conventional drainage pumps unable to keep up due to shallow water depth

Solution: Deployed 4 units of our hydraulic axial flow pumps (500m³/h each) with mobile HPU trailers

Result: 1.2km of flooded roadway drained within 6 hours, restored traffic flow. Pumps ran continuously for 36 hours with zero downtime

2. Jiangsu Municipal Drainage Authority – Underground Garage Flood Prevention (2024)

Scenario: 3 underground parking levels at a shopping mall, water depth reached 1.8m after storm, fixed drainage pumps failed due to power outage

Solution: Two hydraulic axial flow pumps driven by diesel HPUs, deployed via stairwell access

Result: Water level dropped to 0.3m within 4.5 hours. All parked vehicles and electrical substation on B1 level protected

3. Infrastructure Construction Site – Foundation Pit Dewatering (2024)

Scenario: 8m deep excavation site, groundwater ingress exceeded the capacity of electric submersible pumps, site had no 3-phase power supply

Solution: Hydraulic axial flow pump powered by a diesel HPU, with flexible suction hose positioned at the pit sump

Result: Maintained water level below working surface for the entire 3-month foundation construction phase
