[email protected]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.
