India's Pump Capital Gets Its Forgings from Rajkot
Coimbatore has earned its title as India's pump capital — over 2,500 pump manufacturers and 400+ compressor OEMs operate within the city and surrounding districts of Tirupur, Erode and Salem. These manufacturers collectively consume thousands of tonnes of forged components monthly. Shivam Forge has been supplying this cluster from Rajkot for over a decade, delivering ISO-certified forgings with a consistent 30–40% cost advantage over Tamil Nadu-based forging suppliers.
Forged Components for Coimbatore's Pump & Compressor Industry
Pump Shaft Forgings
Solid pump shafts forged in EN8 (C45), EN19 (42CrMo4) and SS410 for centrifugal pumps, submersible pumps and fire-fighting pumps. Turned and ground to h6 tolerance on journal diameters. Straightness within 0.05 mm/m. Standard lengths 300–2,500 mm, diameters 20–200 mm.
Impeller Blanks
Closed-die forged impeller disc blanks in EN8, SS304 and SS316 for centrifugal and multistage pump OEMs. Near-net-shape forging reduces machining time per impeller by 35–45% versus bar or plate machining. OD range 80–600 mm, thickness 15–80 mm.
Compressor Piston Rods
High-strength piston rod forgings in EN24 (AISI 4340) and 42CrMo4 for reciprocating air compressors, process gas compressors and refrigeration compressors. Hard chrome plated (per customer spec) with straightness within 0.02 mm/m. Length up to 3,000 mm.
Valve Seat Rings
Compressor valve seat ring forgings in EN8, stainless steel (SS420, SS410) and AISI 4140 for industrial air and gas compressors. Forged to near-net-shape, OD machined to H7 bore fit tolerance. Hardness 26–32 HRC after heat treatment.
Coupling Forgings
Rigid and flexible coupling half forgings in EN8 and EN19 for pump-motor drive trains. Keyway, spline and tapered bore options. Balanced to G6.3 or G2.5 on request. Standard coupling OD range 50–400 mm.
Motor Shaft Blanks
Motor shaft blanks forged in EN8 and C45 for electric motor rewinding shops and motor OEMs in Coimbatore and Tirupur. Forged, normalized and turned to stock sizes for volume supply. Diameter range 25–150 mm, lengths 300–1,800 mm.
Why Coimbatore OEMs Choose Shivam Forge
30–40% Cost Advantage
Rajkot's forging cluster benefits from lower energy costs, abundant skilled labour and competitive billet sourcing compared to Tamil Nadu.

Materials for Pump & Compressor Forgings
EN8 / C45 Carbon Steel
Most common shaft and impeller blank material for general-purpose pumps. Normalized condition, 580–700 MPa UTS. Cost-effective and widely available. Suitable for pump shafts handling non-corrosive fluids at ambient to 120°C.
EN19 / 42CrMo4 Alloy Steel
Chrome-molybdenum alloy steel for high-performance pump shafts, coupling and motor shafts requiring tensile strength 700–900 MPa after Q&T. Excellent fatigue resistance for cyclic loading in reciprocating compressor applications.
EN24 / AISI 4340 Alloy Steel
High-strength Ni-Cr-Mo steel for compressor piston rods and high-pressure pump shafts. Q&T to 900–1,100 MPa UTS. Superior notch toughness vs. 42CrMo4 for dynamic loading applications. Hard chrome plating adhesion is excellent on this grade.
SS304 / SS316 Stainless Steel
Austenitic stainless forgings for pumps handling corrosive fluids — chemical dosing, seawater, acidic effluent and food-grade liquids. SS316 (2% Mo) provides 30% better pitting resistance than SS304 in chloride environments.
SS410 / SS420 Martensitic Stainless
Martensitic stainless steel for impellers and shaft sleeves in mildly corrosive services where wear resistance is the primary requirement. Hardened to 26–36 HRC after heat treatment. Common in submersible pump impellers and valve seat rings.
Coimbatore is the undisputed pump capital of India — the city and surrounding districts of Tirupur, Erode and Salem are home to more than 2,500 pump manufacturers and over 400 compressor OEMs. This concentration of precision engineering industry consumes enormous volumes of forged components: pump shaft forgings, impeller blanks, piston rods, valve seat rings and coupling halves. Shivam Forge has been a reliable supplier to this cluster from Rajkot, Gujarat for over a decade.
The economics are straightforward: Rajkot's forging industry benefits from India's lowest industrial power tariffs, a deep pool of forging-skilled workers and highly competitive billet procurement — advantages that Tamil Nadu suppliers structurally cannot match. The result is a 30–40% cost advantage on forged components at ISO 9001:2015 quality, delivered to Coimbatore by road in 40–48 hours. For pump OEMs ordering 5–50 tonnes of shafts and impeller blanks per month, this represents a meaningful reduction in raw material cost.
Pump shaft forgings represent our highest-volume product for the Coimbatore market. We supply EN8 and EN19 shafts ground to h6 tolerance on journal diameters for direct assembly into pump bearings — eliminating the grinding step at the customer's facility. Impeller blanks are forged to near-net-shape in SS304 and SS316, reducing machining cycle time by 35–45% per piece. Compressor piston rods in EN24 (AISI 4340) are supplied straight-to-drawing with hard chrome plating coordinated on request.
Coimbatore's compressor OEMs manufacture reciprocating air compressors from 5 HP to 500 HP for industrial, construction and infrastructure markets. The forged components in these machines — piston rods, valve seat rings, crosshead pins and coupling halves — see high cyclic stress and require verified hardness and material quality. Shivam Forge supplies compressor forgings with Brinell hardness certificates, material test certificates and dimensional inspection reports as standard documentation.
