QZB Submersible axial flow pump

A fully integrated submersible axial-flow pump unit designed for heavy-duty drainage, irrigation, flood control and underground pump-station applications. The motor and pump are combined into a single compact assembly for fast, space-saving installation and reliable submerged operation.

Key features

• Integrated motor-pump assembly reduces onsite installation time by up to 95% and minimizes the footprint required for pump-station civil works.
• Submerged motor operation provides efficient cooling, low acoustic emission and eliminates the need for surface-mounted motor enclosures — enabling installation in underground or concealed pump stations and preserving site appearance.
• Sealing and protection: motor uses double- or triple-mechanical seals plus an auxiliary seal, designed for long-term submersion and protected to IP68 standards.
• Electrical insulation and thermal protection: F-class insulation (temperature resistant to 155 °C) for motor windings.
• Built-in condition monitoring: sensors for seal leakage, winding temperature and bearing temperature; detection signals are routed to the electric control cabinet for local monitoring, automatic control and remote supervision.
• Cost and construction benefits: simplified pump-station structure can reduce project civil and architectural costs by an estimated 30–40%.

Applications

• Municipal and industrial drainage
• Agricultural irrigation and river-lift pumping
• Stormwater and flood-control systems
• Underground pump stations where low noise and small surface footprint are required

Operation & control

The unit is compatible with typical pump-station electrical control cabinets and SCADA/remote-control systems. Integrated fault and temperature signals allow automated shutdown or alarm reporting to protect the motor and seals during abnormal conditions.

Supply options

Available as axial-flow (QZB series) and mixed-flow (QHB series) electric submersible pump units. Contact your distributor for available sizes, shaft configurations and motor power ratings to match system head and flow requirements.
