Overview of Railway Cast Iron Pump Cover
Railway cast Iron pump cover is core sealing components designed specifically for railway vehicles (such as diesel locomotives, electric locomotives, and EMUs) and railway infrastructure (such as maintenance bases and station water supply systems). Made from high-strength gray cast iron (HT250/HT300) or ductile iron (QT450) through a precision casting process, they offer excellent pressure resistance, corrosion resistance, and shock absorption. These covers strictly adhere to international railway industry standards (EN과 같은 15085 그리고 아이리스) and are suitable for critical equipment such as fuel pumps, cooling water pumps, and hydraulic pumps. They effectively prevent media leakage, protect internal components, and ensure stable operation of railway systems under complex operating conditions.

Features of Railway Cast Iron Pump Cover
High Strength and Durability
- The spheroidized cast iron (QT450) increases its tensile strength by 30%, allowing it to withstand railway vibration and high-pressure media circulation, reducing the risk of deformation.
- An optimized internal rib design enhances the pump cover’s rigidity and prevents fatigue cracking caused by pressure fluctuations.
Excellent Sealing Performance
- An integrated double mechanical seal achieves a dynamic leakage rate of ≤0.5 mL/h, meeting railway safety standards (GB/T와 같은 34571-2017).
- A pre-designed quick-change seal slot allows maintenance without disassembling the pump body, minimizing downtime.
Environmental Adaptability
- The surface coating has passed the salt spray test (≥1000 hours), making it suitable for coastal, high-humidity, or industrially polluted environments.
- The low-temperature model utilizes an antifreeze formula to ensure seal flexibility at -40°C, preventing brittle fracture.
Lightweight and Modular Design
- The ductile iron model is 15% lighter than traditional gray cast iron, reducing train energy consumption.
- Standardized flange interfaces enable interchangeability between pump bodies from multiple brands, simplifying spare parts management.
Application of Railway Cast Iron Pump Cover
Diesel and Electric Locomotives
- Fuel Pump Cover: Seals diesel or gas to prevent leakage into high-temperature engine areas, suitable for models such as GE and Siemens.
- Cooling Water Pump Cover: Protects the water pump from corrosion caused by ethylene glycol coolant, withstanding temperature cycles from -40°C to +120°C.
- Hydraulic Pump Cover: Used in the braking system or pantograph lifting mechanism, ensures zero hydraulic oil leakage to maintain system pressure.
EMU and Urban Rail Transit Vehicles
- Main Cooling Pump Cover: Integrated exhaust valve design balances steam pressure during high-speed operation, preventing cavitation damage.
- Air Conditioning System Water Pump Cover: Features a food-grade coating to meet train drinking water transport hygiene standards.
Railway Infrastructure and Maintenance Bases
- Lubricating Oil Pump Cover: Used in equipment maintenance stations, withstands frequent starts and stops and the impact of high-pressure lubricating oil.
- Sewage Treatment Pump Cover: Corrosion-resistant design, suitable for wastewater discharge containing particulate matter.
- Station Water Supply Pump Cover: IP67 protection rating, prevents rainwater intrusion and motor short circuits.
Special Environment Routes
- Altitude and Cold Regions: Low-temperature ductile iron models are used to prevent seal hardening and failure.
- Desert Routes: Sand filters are installed to reduce sand intrusion into the pump body.
- Seismic Zones: Shock-absorbing rubber pads are designed to absorb the impact of earthquake waves on the pump cover.
