Manufacturing Process
We follow a hygienic, precision-controlled casting process to deliver food-grade pump components that ensure leak-proof, durable, and contamination-free performance.
Accurate Patterning: Maintains precise geometry for smooth flow paths
Controlled Pouring: Ensures defect-free, clean cast surfaces
Heat Treatment: Enhances corrosion resistance and durability
Precision Machining: Produces sanitary finishes and tight tolerances
Quality Verification: Includes dimensional checks, NDT, and food-grade compliance inspections

Testing & Compliance
We ensure every fire safety pump casting meets international quality, reliability, and safety standards through rigorous testing and compliance checks:
Dimensional Verification – CMM, calipers, and gauges for precise housing, impeller, and sealing surface alignment
Non-Destructive Testing (NDT) – Dye Penetrant, Radiography, and Ultrasonic inspection to detect internal and surface defects
Mechanical & Metallurgical Tests – Hardness, tensile and yield strength, elongation, impact resistance, and microstructure analysis for durability
Performance Testing – Hydrostatic pressure, leak-proof sealing, flow efficiency, and endurance testing as per NFPA 20 / UL / FM guidelines
Corrosion & Surface Testing – Epoxy coating adhesion, passivation quality, and salt spray resistance for long-term protection in harsh environments
Standards Compliance – NFPA 20, UL/FM, ASTM, ASME, API, DIN, EN, JIS
