# Pump and valve components from India: process, clusters and QA > How pump and valve components are made in India, step by step, and where: Coimbatore, Rajkot and Ahmedabad. QA tests, HS heading and lead times. Source: https://sourcesquid.co/india-atlas/products/pump-valve-components/ Product guide # Pump and valve components. How India makes them. Pump and valve components are best sourced from Coimbatore, Rajkot and Ahmedabad, with Kolhapur, Belagavi, Kolkata and Batala supplying castings. Indian suppliers cast, machine and pressure-test pump casings, impellers, valve bodies, bonnets and discs in iron, bronze and stainless steel.

Anything else, ask us directly. A principal replies, not a bot. [anirudh@sourcesquid.co](mailto:anirudh@sourcesquid.co) ### Why is Coimbatore known for pumps? Coimbatore has a large base of pump and motor makers with supporting foundries and machine shops, serving agricultural, domestic and industrial pumps. Coimbatore Wet Grinder is also GI-registered, reflecting its motor-making skills. ### Can I get valve castings to API or EN standards? Yes. Foundries cast valve bodies in WCB, CF8M and ductile iron, and suppliers test to API 598 or EN 12266 as required. ### Can impellers be balanced? Yes. Suppliers balance impellers to the grade you specify, for example G6.3 to ISO 21940-11. More product guides ## Related products.
