Professional Engineering Background

Amar Shah is the Proprietor and Chief Mechanical Engineer at Jagdish Engineering Works (JEW Pumps). Holding a Bachelor of Engineering (B.E.) degree in Mechanical Engineering, he brings over 40 years of hands-on industrial expertise in the mechanical design, metrology testing, and manufacturing of positive displacement pumps and high-pressure chemical relief valves.

Under his leadership, JEW Pumps has engineered and supplied thousands of precision reciprocating plunger metering pumps, glandless diaphragm dosing units, and automated turnkey chemical skids to India’s most demanding petrochemical refineries, fertilizer complexes, pharmaceutical API plants, and international process facilities in the UAE and Saudi Arabia.

Core Technical Competencies & Research Focus

• Severe Chemical Metallurgy Selection: Decades of empirical field experience designing liquid ends in Alloy 20 (CN7M), Hastelloy C-276, Monel, and pure solid PVDF/PTFE for aggressive mineral acids (H₂SO₄, HCl, HNO₃, wet chlorine).
• API 675 Precision Standard Verification: Engineering stroke adjustment mechanisms achieving linear ±1% steady-state flow repeatability across complete 10:1 turndown ratios.
• High-Pressure Relief Valve Engineering: Nitrogen gas bubble testing conforming to API 527 up to 700 bar with proprietary PTFE-encapsulated springs that eliminate acidic stress corrosion cracking.
• Industrial Pump Overhaul & Ceramic Plunger Recoating: Rebuilding imported pump brands (Milton Roy, ProMinent, Lewa) to factory OEM specifications at 40% of replacement cost.
