Acid & Corrosive Fluid Pump Repair

Pumping concentrated mineral acids, boiling organic acids, and oxidizing chemical mixtures represents one of the most aggressive operational challenges in industrial fluid handling. Teflow Pumps provides dedicated acid and corrosive fluid pump repair, relining, and metallurgy upgrading services across Gujarat, ensuring complete chemical containment and extended equipment operating life.

Our acid pump repair methodology focuses on combating aggressive chemical permeation, intergranular corrosion, and high-temperature elastomeric degradation. We service all specialized acid pump constructions including virgin PFA/PTFE lined centrifugal pumps, solid polypropylene/PVDF pumps, high-silicon iron pumps, and Hastelloy C-276/Alloy 20 metallic process units.

During workshop refurbishment, our technicians execute rigorous non-destructive evaluations. Fluoropolymer lined pump volutes, impellers, and rear casings undergo 20 kV high-voltage spark testing to verify total dielectric barrier integrity. Metallic acid pumps undergo ultrasonic wall thickness mapping and microscopic dye penetrant inspections to detect pitting and stress corrosion cracking.

Sealing aggressive acids requires specialized engineering configurations. We replace standard mechanical seals with chemical-resistant dual cartridge seals featuring monolithic silicon carbide or diamond-faced seal rings, perfluoroelastomer (FFKM) secondary O-rings, and Hastelloy springs isolated completely from the acid stream.

Every overhauled acid process pump is dynamically balanced to ISO 1940 Grade 2.5 and hydrostatically tested to 1.5 times working pressure before dispatch. We support acid manufacturing, metal pickling, dye intermediate, and fertilizer plants across Vatva, Naroda, Dahej, Panoli, and Ankleshwar.

Handling concentrated mineral acids such as 98% sulfuric acid, 35% hydrochloric acid, 70% nitric acid, and boiling phosphoric acid presents extreme metallurgical and chemical challenges. Our acid pump repair facility specializes in rebuilding and relining chemical fluid equipment that has suffered severe chemical erosion, acid permeation, and mechanical seal destruction in heavy process industries.

Our technicians perform detailed non-destructive testing (NDT) during teardown. Fluoropolymer lined pump volutes, impellers, and rear covers undergo 20 kV high-voltage dielectric spark testing to detect micro-pinholes and subsurface blistering. Metallic acid pumps undergo ultrasonic casing wall thickness mapping and liquid dye penetrant crack testing to identify stress corrosion cracking and intergranular corrosion along weld seams.

Shaft sealing upgrades are engineered specifically to resist violent acid vapors and salt crystallization. We install dual pressurized cartridge mechanical seals with monolithic silicon carbide (SSiC) or diamond-coated faces, Hastelloy-C springs isolated completely from the acid stream, and perfluoroelastomer (FFKM / Kalrez) secondary O-rings that resist acid swelling and hardening up to 250°C.

During machine shop reconditioning, we machine replacement shafts and sleeves from solid Hastelloy C-276 or Titanium, line-bore bearing brackets to restore ISO H7 tolerance fits, and dynamically balance lined chemical impellers to ISO 1940 Grade 2.5 on computerized dynamic balancing rigs.

Every overhauled acid pump undergoes mandatory hydrostatic casing pressure testing to 1.5 times working pressure rating before final dispatch. We support chemical manufacturing, metal pickling, dye synthesis, and fertilizer complexes across Vatva, Naroda, Dahej, Panoli, and Ankleshwar.

Severe acid service overhauls include compression-molded virgin PFA liner replacement with dovetail vacuum locking grooves, monolithic alpha-sintered silicon carbide seal face lapping, FFKM perfluoroelastomer O-ring renewal, and 20 kV dielectric spark testing. Reconditioned acid process pumps receive certified chemical passivation and high-pressure hydrostatic testing. We verify that all secondary O-rings, containment shells, and fluoropolymer linings provide absolute leak-free fluid containment. Severe acid service overhauls include compression-molded virgin PFA liner replacement with dovetail vacuum locking grooves, monolithic alpha-sintered silicon carbide seal face lapping, FFKM perfluoroelastomer O-ring renewal, and 20 kV dielectric spark testing.
