Product Description

Product Description

HORIZONTAL DIRECT-COUPLED CENTRIFUGAL PUMP
 

The APW series adopts a compact direct-coupled structure in which the motor and pump are connected on the same axis, reducing transmission loss and improving running stability. It is suitable for chilled water, hot water, and general clean water transfer, and is widely used in HVAC circulation, industrial circulation, building booster supply, and packaged equipment systems.
 
This series combines high efficiency, low vibration, low noise, and easy maintenance. It is well-suited for long-term continuous-duty projects and offers a balanced solution in both performance and cost-effectiveness.

KEY SELLING POINTS
 
-Direct-coupled drive: eliminates complicated belt OR coupling transmission, making the structure more compact AND installation easier.
 
-High-efficiency impeller: designed with an optimized hydraulic model FOR excellent balance AND stable output.
 
-Low-noise operation: supported by quality bearings to REDUCE vibration AND operating noise.
 
- Mechanical seal: reliable sealing, less shaft wear, lower leakage risk, and longer service life.
 
- Easy maintenance: the single-stage, single-suction layout simplifies inspection, disassembly, and routine service.
 
- Material options: cast iron is the standard catalog option, with other material solutions available for project requirements.

MAIN CONSTRUCTION
 

The APW series mainly consists of the shaft, bracket, pump casing, plug, O-ring, mechanical seal, impeller, key, feet, and motor.

The overall structure focuses on axial concentricity, sealing reliability, and casing rigidity for long-term stable operation.

FAQ

Q1. Are you a manufacturer or a trading company?

A: We are a global-facing business platform backed by two manufacturing bases in China: one focuses on industrial electric furnaces & melting systems (since 1954), and the other specializes in cooling towers, cooling systems & pumps (since 1996). We provide factory-direct quality plus integrated melting-to-cooling solutions.

Q2. Can we visit your factory?

A: Yes. Factory visits are welcome. You can inspect our production capability, quality control process, and on-site equipment operation. If you share your travel plan in advance, we will arrange the visit and technical discussion accordingly.

Q3. What products do you supply?

A: We supply:

• Induction melting furnaces & thermal processing equipment

• Open-type & closed-circuit cooling towers

• Chillers / air coolers

• Water pumps and supporting system components

We can supply single equipment or complete system solutions.

Q4. What information do I need to provide for a fast quotation?

A: To quote accurately and quickly, please provide the following:

For melting equipment

• Metal type (Al/Cu/Fe/steel, etc.)

• Capacity per heat (kg/ton) and target temperature

• Production schedule (heats/day) and power supply condition (voltage, transformer capacity)

For cooling systems

• Flow rate (m³/h), inlet/outlet temperature

• Project location (wet-bulb temperature if available)

• Water quality (clean/dirty/sediment/scale risk)

• Installation limits (space, noise, plume/drift requirements)

We will recommend a suitable model and configuration based on your working conditions.

Q5. Can you provide customized solutions (OEM/ODM)?

A: Yes. We support customization for capacity, voltage, structure, corrosion protection, noise control, and modular installation. OEM branding is also available.

Q6. How do you ensure product quality?

A: We use qualified raw materials and mature manufacturing processes, with inspection and testing before shipment. Our solution is built on long-term industrial manufacturing experience and practical engineering design.
