Product Overview

SPG Series Vertical Canned Motor Clean Water Pump is a vertically installed seal-less centrifugal pump integrating motor and hydraulic section into a hermetically sealed unit.

It addresses mechanical seal leakage, maintenance downtime, and external emission risks in closed-loop clean water systems.

It is used in high-rise building mechanical rooms, HVAC closed circulation loops, boiler auxiliary systems, and confined piping installations where leakage is not permissible.

✔ Engineered for closed clean-water systems requiring zero external leakage.

Model DesignationSPG Vertical Shielded Clean Water Pump for Building Supply

Applications

Operating Scenarios

• Closed-loop chilled and hot water circulation systems
• High-rise building vertical riser circulation networks
• Boiler auxiliary clean water transfer circuits
• Industrial equipment internal cooling circulation
• Pipeline systems where external leakage is not permissible

Engineering Advantages

• Hermetically sealed canned motor structure → Eliminates dynamic shaft seal interface and leakage path

• Integrated rotor-pump shaft design → Ensures concentric alignment and reduces mechanical vibration

• Liquid-lubricated sleeve bearing system → Utilizes pumped medium for cooling and lubrication

• Vertical in-line hydraulic layout → Reduces installation footprint in pipe gallery systems

The pump is configured for clean water service under ≤80°C operating conditions and ≤1.6 MPa system pressure.

✔ Structural integration ensures stable hydraulic performance and leakage-free operation in closed systems.

System Components

How to Select a Pump Model

  1. Confirm required flow rate and total head in closed-loop condition.
  2. Ensure medium cleanliness suitable for liquid-lubricated bearing system.
  3. Verify system pressure does not exceed 1.6 MPa.
  4. Select speed (1450 / 2900 rpm) based on hydraulic efficiency and noise constraints.
  5. Check vertical pipe installation space and flange compatibility.
✔ Model configuration shall be determined according to duty point and system parameters.

Engineering Notes

• Seal-less configuration eliminates routine mechanical seal replacement.
• Internal circulation ensures rotor cooling under continuous operation.
• Pumped liquid acts as bearing lubrication medium.
• Designed exclusively for clean, non-corrosive water applications.
• Not suitable for abrasive or high-viscosity media.

Compliance & Quality Assurance

• Factory hydrostatic pressure test
• Rated duty hydraulic performance test
• Rotor dynamic balance inspection
• Motor insulation resistance test
• Wetted material traceability verification

Safety Notice

• Do not operate under dry-running condition
• Ensure system is fully filled before energizing
• Do not use for abrasive or corrosive fluids
• Disconnect power supply before maintenance

OEM & Customization

This pump series supports engineered configuration and duty-based matching. Technical adjustments can be made according to system requirements and installation conditions.

Available options include:
• Motor voltage & frequency
• Bearing material selection
• Flange standard (DIN / ANSI)
• Insulation class upgrade
• Special corrosion-resistant wetted components

Configuration is determined based on duty point and project specifications.

FAQs

Q1: Can the pump operate under VFD control?
A: Yes, within rated speed range while ensuring adequate cooling flow.

Q2: What is the maximum allowable working pressure?
A: ≤ 1.6 MPa.

Q3: What medium is permitted?
A: Clean water without abrasive particles.

Q4: What is the maximum liquid temperature?
A: ≤ 80°C.

Q5: How are bearings lubricated?
A: By the pumped liquid through internal circulation.

Q6: Is mechanical seal replacement required?
A: No, the canned motor structure eliminates mechanical seals.

Q7: Can it be used in open systems?
A: It is primarily designed for closed-loop systems.
