Installation Guide

  • Pipeline Support: The weight of the pipeline should not be borne by the pump. Each pipeline should have its own support system to prevent pump deformation, which may affect performance and shorten its service life.
  • Maintenance and Safety: To facilitate maintenance and ensure safe operation, install a regulating valve on both the inlet and outlet pipelines of the pump. Additionally, a pressure gauge should be placed near the pump outlet to monitor operating conditions. This ensures the pump runs within its rated head and flow range, thereby extending its service life.
  • Suction Conditions: When the pump operates under suction conditions, a foot valve must be installed. The inlet pipeline should be designed with as few bends as possible, and there must be no water or air leakage.
  • Pre-Operation Check: After installation, manually rotate the pump shaft. The impeller should rotate smoothly without friction or obstruction. If any resistance is detected, disassemble the pump to identify and resolve the cause.
  • Connection Methods: There are two installation methods for the pump: rigid connection and flexible connection. Choose the appropriate method based on the installation environment and system requirements.

How to Select a Pump Model

• Calculate the required flow rate and total dynamic head based on system design.

• Determine whether the pump’s horizontal installation fits the available installation space.

• Verify the application conditions (liquid type, temperature) to select the proper material for wetted parts.

• Ensure the selected pump meets the reliability and maintenance frequency requirements of the system.

✔ Final pump selection should be based on accurate system design parameters and operational conditions.

Engineering Notes

• Ensure that the pump is operated within the calculated duty point for optimal efficiency.

• Maintain proper alignment between the motor and pump shaft to prevent premature wear.

• Installation should account for easy access for maintenance and repair operations.

• Verify that all seals are properly installed and lubricated during initial setup.

Compliance & Quality Assurance

• Factory performance testing including hydraulic, mechanical seal, and pressure tests.

• Material certification for wetted parts.

• Electrical and insulation resistance tests.

• Third-party inspection services available upon request.

Safety Notice

• Ensure proper priming before pump startup.

• Do not operate under dry-running conditions.

• Disconnect power before performing maintenance or repair work.

• Do not exceed the rated operating pressure.

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
• Mechanical seal type and configuration
• Wetted parts material selection
• Surface coating and corrosion protection

Configuration is determined based on duty point and project specifications.

FAQs

Q1: Can the pump operate under VFD control?
Yes, VFD integration is possible for energy-efficient operation with variable flow.

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

Q3: Is the detachable design easy to maintain?
Yes, the detachable structure allows easy removal and servicing without disassembling pipelines.

Q4: Can this pump handle liquids with solid particles?
No, it is designed for clean water; handling of solids requires special configurations.

Q5: How frequently should the pump seals be replaced?
Seals should be checked and replaced every 2–3 years depending on operational conditions.

Q6: What is the required NPSH?
The required NPSH can be found in the pump performance curve, depending on flow and head.
