H2 How to Select a Pump Model

Select based on required rated fire flow and system design pressure.

Confirm pump curve meets fire code duty point at rated speed.

Verify motor power margin under full load operation.

Check allowable working pressure versus pipeline rating.

Consider installation space and vertical alignment requirements.

✔ Model selection must strictly match fire code rated duty point.

Engineering Notes

Designed for emergency fire activation; not intended for continuous process boosting.

Pump performance must comply with local fire hydraulic standards.

Vertical configuration reduces floor load concentration.

Suitable for integration with fire control panels and pressure controllers.

Compliance & Quality Assurance

• Hydraulic performance test according to rated fire duty

• Pressure casing hydrostatic test

• Impeller dynamic balance verification

• Motor insulation and protection class verification

• Material traceability documentation

Safety Notice

• Do not operate without water filling.

• Ensure system priming before emergency start.

• Verify rotational direction before commissioning.

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

Configuration is determined based on duty point and project specifications.
Based on duty point and project specifications.

H2 FAQs

Q: Can the pump operate under VFD control?
A: Fire pumps are typically operated at rated speed; VFD use must comply with fire code regulations.

Q: What is the allowable working pressure?
A: Maximum working pressure is 1.6 MPa as per casing design.

Q: What sealing options are available?
A: Mechanical seal or packing seal depending on fire system specification.

Q: What standards does the pump comply with?
A: Designed to meet hydraulic requirements of fixed fire protection systems.

Q: What is the rated speed?
A: Standard configuration is 2900 rpm for 50Hz systems.

Q: Is parallel pump operation supported?
A: Yes, parallel configuration can be applied for higher system flow demand.
