Why Choose 316L Stainless Steel for Your Split Case Pump?
1. Superior Corrosion Resistance
316L stainless steel contains molybdenum (2-3%), which provides enhanced resistance to:
- Chloride pitting
- Crevice corrosion
- Acidic conditions (sulfuric, phosphoric, organic acids)
- Alkaline solutions
This makes the XSP in 316L ideal for:
- Cooling water systems with treated or raw water
- Industrial process water with mild chemical content
- Municipal water treatment plant feed
- Food and beverage processing water
- Pharmaceutical utilities
2. Low Carbon Content for Better Weldability
The “L” in 316L stands for Low carbon (maximum 0.03% versus 0.08% for standard 316). This:
- Prevents carbide precipitation during welding
- Eliminates the need for post-weld heat treatment
- Maintains corrosion resistance in heat-affected zones
- Allows field modifications or repairs
3. Sanitary & Hygienic Properties
316L stainless steel is:
- Non-porous and easy to clean
- Resistant to bacterial growth
- Compliant with food and pharmaceutical standards
- Suitable for potable water service
4. Long Service Life
Unlike cast iron pumps that rust internally over time, a horizontal 316L stainless steel split case pump maintains clean, smooth wetted surfaces for decades. This means:
- No rust contamination of your process fluid
- No performance degradation from internal corrosion
- Lower total cost of ownership over 20+ years
5. Cost-Effective Corrosion Solution
While duplex stainless steels (SS2205, SS2507) offer higher corrosion resistance for seawater, 316L provides:
- Excellent corrosion resistance for most fresh water, cooling water, and mildly corrosive industrial applications
- Lower cost than duplex or super duplex alloys
- Better availability globally

XSP Series vs Competitors: Why Durafort Pumps Stands Out
При поиске horizontal 316L stainless steel split case pump manufacturer in China, consider these differentiators:
| Фактор | Competitors | Насосы Durafort |
|---|---|---|
| 316L casting quality | Variable | Precision castings with certification |
| Material traceability | Limited | Full material test reports |
| Flow range | Limited models | 135 – 38,000 m³/h covers all applications |
| Настройка | Slow | Engineering team available for custom designs |

Key Features of XSP Horizontal 316L Stainless Steel Split Case Pump
A. Рабочее колесо с двойным всасыванием — скомпенсированная осевая тяга
The double-suction impeller design in 316L stainless steel provides:
- Flow enters from both sides → axial thrust cancels
- Подшипники меньшего размера, которые меньше нагреваются
- Longer bearing life (5-10 years typical)
- Lower vibration levels
- Reduced maintenance frequency
B. Horizontal Split Casing – Easy Maintenance in 316L
The casing splits horizontally along the centerline. To inspect or service:
- Снимите гайки на верхней крышке
- Lift upper casing half (316L construction ensures no warping)
- Рабочее колесо, изнашиваемые кольца и уплотнения
- Нет необходимости отсоединять всасывающий или нагнетательный трубопровод
Сокращение времени простоя: 50-80% — меньше времени по сравнению с насосами с торцевым всасыванием.
For 316L specifically: The material’s low carbon content means even if welding repairs are needed, corrosion resistance remains intact.
C. Высокая эффективность — снижение затрат на электроэнергию
Насосы XSP с разъемным корпусом achieve КПД 85-92% at best efficiency point (BEP). For a pump operating 8,000 hours per year:
| Efficiency Advantage | Annual Energy Savings (1,000 kW motor) |
|---|---|
| 5% higher efficiency | $40,000+ |
| 8% higher efficiency | $64,000+ |
| 10% higher efficiency | $80,000+ |
The 316L stainless steel construction maintains this efficiency over time because internal surfaces do not rust or scale like cast iron.
D. Низкие требования к NPSH — более высокая производительность всасывания
The double-suction design reduces inlet velocity, lowering NPSH required. Benefits include:
- Установка на большей высоте над уровнем воды
- Эксплуатация с частичным погружением
- Reliable performance in irrigation, river intake, and retrofit applications
E. Complete 316L Wetted Parts
Unlike some manufacturers that use 316L only for certain components, Durafort Pumps’s XSP in 316L features:
- 316L casing
- 316L impeller
- 316L shaft
- 316L wear rings
- 316L hardware
Результат: No galvanic corrosion from dissimilar metals. Complete compatibility with corrosive fluids.
F. Temperature Rating to 150°C
The 316L stainless steel construction maintains strength and corrosion resistance up to 150°C, making the XSP suitable for:
- Циркуляция в системе централизованного теплоснабжения
- Промышленные системы горячего водоснабжения
- Вспомогательное охлаждение электростанции
- Process water at elevated temperatures

Часто задаваемые вопросы
Q1: Why choose 316L stainless steel instead of standard 316?
A: The “L” stands for Low carbon (maximum 0.03% vs 0.08% for standard 316). This prevents carbide precipitation during welding, eliminating the need for post-weld heat treatment and maintaining corrosion resistance in welded areas. For pump applications where modifications or repairs may be needed, 316L is superior.
Q2: Is 316L suitable for seawater service?
A: For continuous seawater service, Durafort Pumps recommends SS2205 Дуплекс или SS2507 «Супердуплекс» stainless steel. 316L can be used for intermittent seawater exposure or low-chloride brackish water, but duplex alloys offer better pitting resistance for full seawater duty.
Q3: What is the maximum flow of the XSP in 316L?
A: Серия XSP обеспечивает расход от от 135 до 38 000 м³/ч in 316L stainless steel, the same as cast iron construction.
Q4: How does 316L compare to cast iron for cooling water?
A: Cast iron pumps corrode over time in cooling water service, leading to rust contamination, reduced efficiency, and eventual failure. A horizontal 316L stainless steel split case pump maintains clean internal surfaces, constant efficiency, and offers 2-3 times longer service life.
Q5: Can Durafort Pumps provide 316L pumps with special coatings?
A: Yes. While 316L itself provides excellent corrosion resistance, Durafort Pumps can apply specialized coatings for additional protection in aggressive environments. Contact our engineering team for specific recommendations.
Q6: Does Durafort Pumps export 316L split case pumps internationally?
A: Да. Как опытный horizontal 316L stainless steel split case pump manufacturer in China, Durafort Pumps has exported stainless steel pumps to Southeast Asia, the Middle East, Africa, South America, and Central Asia.
Q7: What certifications does Durafort Pumps provide for 316L materials?
A: Durafort Pumps provides mill test reports (MTRs) certifying chemical composition and mechanical properties for all 316L stainless steel components. Third-party inspection is available upon request.
