VIF150/32  UL Listed Vertical Inline Fire Pump  1000–1500 GPM Designed For NFPA 20 Fire Protection Systems

NMFIRE fire pump packages are manufactured through advanced hydraulic design, precision machining, and strict quality control processes to ensure reliable operation in critical fire protection applications.

Advanced Computational Fluid Dynamics (CFD) analysis and 3D hydraulic design are applied to optimize internal flow performance:

• Improved hydraulic efficiency
• Reduced hydraulic losses
• Lower required engine power
• Stable flow and pressure performance

Pump casing manufacturing adopts Lost Foam Casting Technology to improve surface quality and hydraulic performance. Manufacturing capabilities include:

• CNC processed metal patterns
• Automatic molding line
• Automatic sand processing production line
• Intermediate frequency melting furnace
• VOD refining furnace
• Precision wax casting technology

Critical components are processed through precision CNC machining. Quality control includes:

• Impeller machining and dimensional inspection
• Shaft machining and runout verification
• Assembly alignment verification
• Dynamic balancing test for all rotating components

Each NMFIRE fire pump package undergoes factory performance verification before delivery per NFPA 20 requirements. Testing includes:

• Shut-off (churn) pressure testing — must not exceed 140% of rated pressure
• Rated flow and rated pressure verification
• 150% rated flow verification — pressure must be ≥65% of rated pressure
• Pressure-flow curve recording (minimum 5 test points)
• Operating parameter monitoring (vibration, temperature, noise)

Our dedicated fire pump test bench enables:

• Accurate flow measurement via calibrated flow meter
• Pressure monitoring at suction and discharge
• Complete performance curve generation
• Third-party witness testing arrangement per project requirements

For seawater service, corrosion-resistant, or other special material requirements, please contact us to discuss.

Fire protection projects often require complete technical documents for consultant approval and installation. NMFIRE provides project-specific engineering support.

Available Documents:

• General Arrangement (GA) Drawing — dimensional layout with baseplate, pump, and motor
• Pump Performance Curve — factory test curve with rated, 150% flow, and shut-off points
• Technical Datasheet — complete pump specifications per project requirements
• Motor Datasheet — motor specs with enclosure and ambient temperature selection
• Controller Datasheet — UL Listed fire pump controller specifications
• Factory Test Report — witnessed performance test results
• Installation, Operation & Maintenance (IOM) Manual
• UL Listed Certification Documents

For skid-mounted or containerized packages, controller layout can be included in the GA drawing upon request. For other special document requirements, please contact us to discuss.

Yes. NMFIRE fire pump packages are designed according to NFPA 20 requirements and available with UL Listed certification; FM Approved is offered on selected models. Each pump is factory performance tested per NFPA 20 including shut-off pressure verification (max 140% of rated), rated flow testing, and 150% rated flow verification at no less than 65% of rated pressure.

Horizontal split case pumps are bidirectional and easier to maintain (the upper casing can be removed without disturbing piping), typically used for medium to high flow. Vertical inline pumps have a compact vertical design that fits tight pump rooms and rooftops where horizontal pumps cannot be installed, with the motor directly coupled above the pump. Both types are available with UL Listed certification per NFPA 20. Selection depends on project flow, available space, and installation constraints.

NMFIRE offers horizontal split case, end suction, vertical inline, and vertical turbine pump types. The VIF150/32 vertical inline model is UL Listed and electric motor driven as standard; other types are available with UL Listed and FM Approved certification per NFPA 20. Vertical turbine pumps are suited to deep well and wet pit applications. Complete packages include fire pump, motor/engine driver, controller, jockey pump, relief valve, and standard accessories per NFPA 20.

Yes. Technical documents including General Arrangement (GA) drawings, pump performance curves, technical datasheets, motor datasheets with enclosure selection, controller datasheets, factory test reports, and installation manuals are available for project submission. Our engineering team provides project-specific submittal packages.

Yes. Factory inspection and third-party witness testing can be arranged according to project requirements. Our dedicated fire pump test facility enables accurate flow measurement, pressure monitoring, and complete performance curve generation. Third-party inspection agencies are welcome to participate in factory testing per project requirements.

For electric motor driven fire pumps, altitude does not reduce motor power output, so no altitude derating is required. However, motor enclosure and insulation class are selected for the installation environment — TEFC (Totally Enclosed Fan Cooled) is standard for NMFIRE VIF packages and is suited to high-temperature, dusty, or hazardous areas. NMFIRE engineering selects the motor rating based on actual site conditions to ensure reliable starting and operation at the specified duty point; supply voltage, phase, and frequency are confirmed at order.

NMFIRE offers single electric, 1 electric + 1 diesel, and 2 electric configurations, as well as containerized fire pump houses for pre-assembled, plug-and-play installation. Material options include standard fresh water, corrosion resistant (stainless steel 316L), and seawater service (duplex stainless steel). Controller options include UL Listed fire pump controllers compatible with the selected driver. Configuration is selected per NFPA 20 and project requirements.
