SCF100-80-200  UL/FM Horizontal Split Case Fire Pump  300–500 GPM, 300 GPM @ 132 PSI  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 motor 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

The SCF100-80-200 is electric motor driven at 3550 RPM (60 Hz), with motor size matched to each duty point from 40 to 60 HP:

• ODP (Open Drip Proof) — economical enclosure for clean, dry, well-ventilated indoor pump rooms
• TEFC (Totally Enclosed Fan Cooled) — sealed enclosure for dusty, humid, hot, or outdoor-adjacent environments; the common choice for African project sites

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

Standard Documents:

• Factory Test Report — including the pump performance curve
• Pump Drawings — outline and dimensional drawings

For skid-mounted or containerized packages, or any other document requirements, please contact us to discuss.

A horizontal split case fire pump has a casing split along the shaft centerline. Lifting the upper casing half exposes the impeller, wear rings, and shaft for inspection or parts replacement — without disconnecting the suction or discharge piping. The impeller is supported between two bearings, giving smooth, stable operation across a wide flow range. The NMFIRE SCF100-80-200 applies this design to the 300–500 GPM range with UL Listing and FM Approval per NFPA 20.

UL (Underwriters Laboratories) Listing and FM (FM Approvals) certification are two independent third-party certifications verifying that a fire pump meets the applicable standards (such as UL 448 and FM 1311). Both are widely accepted by fire protection consultants, insurers, and authorities having jurisdiction in export markets. Many projects specify either one; some require both. The SCF100-80-200 carries both UL Listing and FM Approval, giving maximum flexibility for consultant approval and insurance acceptance on international projects.

The SCF100-80-200 covers rated flows of 300, 400, 450, and 500 GPM, with pressure ratings from 91 to 132 PSI (head 64–93 m). At the 300 GPM duty point, pressure options range from 103 to 132 PSI, driven by a matched 40–60 HP electric motor at 3550 RPM (60 Hz) in ODP or TEFC enclosure. The full selection table and performance curves for each flow/pressure combination are available on request.

Sizing starts from the hydraulic calculations of the sprinkler or standpipe system: the required flow (GPM) at the most demanding point plus hose stream allowance, and the pressure needed to overcome elevation, friction losses, and required residual pressure, minus available municipal supply pressure. The selected pump must then meet the NFPA 20 performance criteria: at 150% of rated flow, discharge pressure must be ≥65% of rated pressure; at shut-off, pressure must not exceed 140% of rated. NMFIRE engineering can verify your duty point against the SCF100-80-200 selection table and issue a project-specific performance curve for consultant approval.

Horizontal split case pumps are the most common fire pump type: easy to service in place, and suitable for medium to high flow duties (the SCF100-80-200 covers 300–500 GPM). End suction pumps offer a simple, economical layout for lower duties. Vertical inline pumps have the most compact footprint for space-limited plant rooms and retrofits. All three types are available from NMFIRE with UL Listed and FM Approved certification per NFPA 20. Selection depends on project flow, available space, and maintenance strategy.

Most African countries have no domestic fire pump manufacturing standard; NFPA 20 is the reference standard most commonly adopted by fire consultants, insurers, and regulators across Nigeria, Ghana, Kenya, Tanzania, South Africa, and the wider region. UL Listing and FM Approval are the recognized third-party certifications for imported fire pumps. NMFIRE supplies NFPA 20-compliant, UL/FM certified fire pumps and project documentation suited to consultant approval processes in these markets.

A 300 GPM fire pump is a typical duty for ordinary hazard occupancies: warehouses and logistics centers (a frequent requirement in Nigeria and across Africa), mid-rise commercial and residential buildings, hotels, shopping malls, schools, hospitals, and light manufacturing plants. With pressure up to 132 PSI at 300 GPM, the SCF100-80-200 also covers standpipe systems in mid-rise buildings. For higher flow duties (750 GPM and above), NMFIRE offers larger SCF series split case models.

ODP (Open Drip Proof) motors are ventilated through open openings and suit clean, dry, well-ventilated indoor pump rooms — typically the lower-cost option. TEFC (Totally Enclosed Fan Cooled) motors are sealed against dust and moisture with an external cooling fan, making them the recommended choice for dusty, humid, hot, or corrosive environments common in African and industrial sites. Both options are available for the SCF100-80-200 from 40 to 60 HP; enclosure selection is confirmed per project site conditions.

The SCF100-80-200 pump unit itself comprises the horizontal split case pump and its electric motor. For projects requiring a complete fire pump system, NMFIRE can configure packages that add a UL/FM listed fire pump controller, a jockey pump for pressure maintenance, and a pressure relief valve where required. Delivery options include conventional plant room installation, a skid-mounted fire pump system with pre-piped pump and jockey pump on a common base, and a fully containerized fire pump station pre-assembled for plug-and-play site connection. Package scope is configured per NFPA 20 and project requirements.

Yes. NMFIRE fire pump packages are designed according to NFPA 20 requirements. The SCF100-80-200 horizontal split case model is UL Listed and FM Approved. 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.

Yes. Factory test reports including pump performance curves, together with pump outline and dimensional drawings, are provided as standard technical documents. For skid-mounted or containerized packages, or any other document requirements, please contact us to discuss. Third-party witness testing at our fire pump test facility can also be arranged per project requirements.
