YST Series Fire Pumps (Up to 125 HP) for Saudi Arabia’s Growing Market
Saudi Arabia’s fire pump market is expanding steadily, driven by stricter enforcement of fire safety codes across commercial, industrial, and infrastructure projects. For engineering contractors and electromechanical traders sourcing equipment, the YST series from Yoking offers diesel and electric fire pump configurations rated up to 125 HP, aligned with NFPA 20 and local civil defense requirements.

Market Context: Why Fire Pump Demand Is Rising in Saudi Arabia
Saudi Vision 2030 has accelerated construction in NEOM, the Red Sea Project, and existing urban centers. Updated Saudi Building Code (SBC) and NFPA 20 adoption mandate certified fire pump systems for high-rise buildings, petrochemical facilities, and data centers. This creates sustained demand for industrial fire pumps with verified performance curves and third-party witness testing.
Importantly, Saudi projects typically require diesel engine-driven fire pumps as primary or backup units, given grid reliability concerns in remote industrial zones. Electric fire pumps are common for jockey pump duties and secondary systems. The YST series covers both configurations within its 125 HP ceiling.
YST Series: Configuration and Power Range
The YST series is designed for fixed fire protection installations. Key specifications:
| Configuration | Power Range | Application |
|---|---|---|
| YST-D (Diesel) | 25 HP – 125 HP | Primary fire pump per NFPA 20 |
| YST-E (Electric) | 10 HP – 125 HP | Main or jockey pump duty |
| YST-J (Jockey) | 5 HP – 30 HP | Pressure maintenance |
All configurations use horizontal split-case centrifugal pumps or end-suction centrifugal pumps depending on flow requirements. Diesel units include engine-mounted cooling, fuel tank, and battery systems. Electric units are available in 50 Hz and 60 Hz for regional compatibility.
Maximum rated flow for the 125 HP diesel configuration reaches approximately 1,500 GPM (340 m³/h) at pressures up to 12 bar (175 psi), subject to specific impeller trim. Exact performance depends on suction conditions and discharge head requirements.
Sizing Logic: Matching YST Models to Project Specifications
Selecting the correct YST model requires three inputs from the project hydraulic calculation:
- System demand flow (GPM or m³/h) — typically the sum of sprinkler and hose stream allowances
- Total dynamic head (feet or meters) — including static lift, friction loss, and residual pressure
- Net Positive Suction Head available (NPSHa) — critical for installations with elevated tanks or suction lift conditions
For Saudi projects, common sizing scenarios include:
- High-rise residential (Riyadh/Jeddah): YST-E 75 HP electric, 1,000 GPM at 150 psi
- Industrial warehouse (Jubail/Dammam): YST-D 125 HP diesel, 1,500 GPM at 175 psi
- Commercial complex: YST-J 15 HP jockey + YST-E 50 HP electric main
NPSH required for YST models ranges from 3.5 m to 6.5 m depending on speed and impeller diameter. Always verify NPSHa exceeds NPSHr by minimum 0.5 m margin per HI 1.3 guidelines.
Compliance and Testing for Saudi Projects
Saudi civil defense and project consultants typically require:
- Factory performance test per ISO 9906 Grade 2B or 1B
- NFPA 20 compliance documentation
- UL/FM listing or equivalent third-party certification for insurance purposes
Yoking provides factory test reports with each unit. For critical projects, witnessed testing at the Taizhou, Zhejiang facility can be arranged with 30–45 days lead time for custom configurations. Standard models ship in 15–20 days.
Common Questions
Q: Can YST 125 HP diesel pumps handle Saudi summer temperatures (50°C ambient)? Yes, with radiator-cooled diesel engines rated for tropical conditions. Specify ambient temperature at inquiry to confirm cooling package sizing.
Q: What is the MOQ for YST fire pumps? Standard models: 100 units for small power, 50 units for 75 HP and above. Project-specific configurations: 50 units.
Q: Does Yoking provide pump curves and submittal drawings? Yes. Performance curves, dimensional drawings, and electrical schematics are issued after model confirmation for consultant approval.
Q: Can YST pumps be configured for 60 Hz operation? Yes. Electric motors are available in 60 Hz for projects with US-specification power systems.
Q: What payment terms apply for Saudi Arabia projects? 30% deposit, 70% before shipment. Letter of Credit (LC) available for qualified buyers.
Conclusion / CTA
Saudi Arabia’s fire safety infrastructure investment creates a multi-year procurement window for certified industrial fire pumps. The YST series (up to 125 HP) provides diesel, electric, and jockey configurations with factory testing and NFPA 20 alignment.
