Product Summary

The QDX Series Clean Water Submersible Pump is a compact, energy-efficient submersible pump engineered for dependable clean water transfer across residential, agricultural, and commercial settings. Built with a cast iron pump body, aluminum motor housing, and a ceramic/graphite mechanical seal, the QDX submersible water pump covers flow rates from 1.5 m³/h to 90 m³/h with heads up to 33 meters. Both single phase and three phase models are available, supporting 50Hz and 60Hz power systems worldwide. Whether the task is garden irrigation, well water supply, or site dewatering, the QDX electric submersible pump delivers practical performance with a straightforward setup.

Detailed Description

The QDX submersible pump is a direct-coupled, vertically mounted centrifugal pump that operates fully submerged. Unlike surface suction pumps that need manual priming before each start, the QDX clean water submersible pump starts drawing water immediately once powered — no pre-filling required. The surrounding liquid also cools the motor continuously during operation, which contributes to stable thermal management during longer duty cycles.

The product line covers 26 models from 0.25 kW to 3.0 kW, with outlet sizes ranging from 1" (25mm) to 8" (200mm). This range makes the QDX submersible pump equally at home in compact household water supply setups and larger-scale agricultural or commercial dewatering installations. Single phase variants (QDX prefix) suit standard residential circuits, while three phase models (QX prefix) address commercial and light industrial installations where three phase infrastructure is standard.

Key Product Features

• 26-Model Range: Flow rates from 1.5 to 90 m³/h, heads from 5 to 33 m, power from 0.25 kW to 3.0 kW — the QDX submersible pump lineup covers an unusually wide working envelope within a single series
  
  
• Single Phase and Three Phase Options: QDX (single phase) and QX (three phase) models share identical dimensions and specifications, simplifying procurement for installations that require both
  
  
• Global Voltage Support: Standard 220V/50Hz configuration with 110V/60Hz and 220V/60Hz available on request, making the QDX electric submersible pump deployable across markets in Asia, Europe, the Americas, and beyond
  
  
• Built-in Thermal Protector: Automatically interrupts the circuit if motor winding temperature exceeds safe thresholds — an important safeguard during unexpected dry running or short-term overload
  
  
• IPX8 Protection Rating: Fully sealed design for continuous submerged operation at depths up to 5 meters in clean water
  
  
• S1 Continuous Duty Cycle: Rated for uninterrupted operation, making the QDX submersible water pump reliable for applications that demand extended daily run times
  
  
• Lightweight Construction: Aluminum motor housing and impeller keep overall weight manageable, easing installation and retrieval in confined spaces like wells and storage tanks

Engineering Advantages

The QDX electric submersible pump operates fully submerged, eliminating surface-side noise and above-ground pipework — a practical advantage for residential and commercial installations where quiet operation matters as much as pump output. The ceramic/graphite mechanical seal resists fine-particulate abrasion and maintains consistent sealing under continuous rotational stress, supporting reliable long-term service in clean water applications without frequent maintenance intervals. For distributors, standardized motor housing dimensions across the full power range simplify spare parts inventory, and the standard plug-and-cable configuration enables field installation and unit swap-out without specialist tools — reducing procurement lead times and streamlining after-sales support across the full model range.

Primary Applications

The QDX Series submersible pump is well-suited to a broad range of clean water handling tasks across industries and settings:

• Residential and household water supply from shallow wells, cisterns, or storage tanks
• Garden, landscape, and agricultural field irrigation systems requiring consistent flow
• Pond, lake, and reservoir water transfer for aquaculture management or irrigation storage
• Construction site and basement dewatering during excavation or post-flooding recovery
• Decorative fountain and recirculating water feature systems
• Light industrial and commercial water transfer in clean processing or manufacturing environments
• Backup water supply during infrastructure maintenance when mains service is temporarily suspended

Commercial Value

For B2B purchasers and distributors worldwide, the QDX–Series submersible pump delivers solid commercial value. It includes 26 models with single–phase and three–phase versions sharing identical structure and optional global voltages, easing inventory and cross–border procurement. Featuring IPX8 protection, thermal safety and low–maintenance design, it wins long–term end–user loyalty. Standardized parts also simplify after–sales service for project teams. With balanced cost–performance, it suits agricultural, residential and commercial markets globally.

FAQ

Q: What type of liquid is the QDX submersible pump suitable for?
The QDX Series handles clean water only. The liquid must be free from abrasive particles, chemical contaminants, and suspended solids that could damage the impeller or seals. It is not designed for sewage, slurries, or chemically aggressive media.

Q: How deep can the QDX submersible water pump be installed?
The maximum rated immersion depth is 5 meters. Going beyond this depth puts added pressure on the seals and may shorten service life over time. Applications requiring greater installation depth should use a deep well submersible pump rated for the required depth.

Q: Can the QDX electric submersible pump work on a 60Hz power supply?
Yes. 60Hz versions supporting 110V and 220V are available on request, making the QDX submersible pump compatible with power grids in North America, parts of South America, Japan, and other 60Hz regions. Confirm the required voltage and frequency when placing an order.

Q: Does the QDX pump need priming before it starts?
No. As a submersible pump, the QDX unit starts pumping as soon as power is connected, provided the inlet is fully submerged. There is no priming procedure — the submersed position takes care of that automatically.

Q: What maintenance does the QDX clean water submersible pump typically require?
Under normal clean water operating conditions, routine maintenance is minimal. Periodic inspection of the power cable for wear or damage, checking the inlet screen for blockages, and verifying the seal integrity after extended service periods are the main recommended checks. The built-in thermal protector and IPX8 sealed design reduce the likelihood of unplanned downtime in typical installations.
