    End-to-end industrial pump overhaul in Gujarat — full mechanical restoration, precision machining, rotor balancing, and hydro-testing for plant turnarounds.

    Overview

    About this service

    Scheduled plant turnaround shutdowns present the ideal window to execute complete, end-to-end industrial pump overhauls. Rather than patching individual worn components, a comprehensive overhaul restores all mechanical and hydraulic clearances across the entire pump assembly back to factory-new OEM specifications. Teflow Pumps provides complete industrial pump overhauls for chemical, petrochemical, power, and manufacturing plants across Gujarat.

    Our systematic overhaul process begins with comprehensive tagging, decontamination, and complete component disassembly. Our senior rotating equipment specialists measure all critical dimensional tolerances: shaft total indicated runout (TIR), bearing housing bore concentricity, wear ring diametrical clearances, impeller vane thickness, and casing wall degradation.

    Precision machine shop restoration encompasses line boring of worn bearing brackets, precision lathe machining of shaft sleeve journals, dynamic balancing of multi-stage and single-stage impellers to ISO 1940 Grade 2.5, and replacement of all wear rings to eliminate internal hydraulic slippage.

    All wear-sensitive components are systematically renewed. We install matched precision angular contact and deep groove ball bearings (SKF/FAG), new cartridge mechanical seals with chemical-resistant face materials (silicon carbide / tungsten carbide / FFKM), and fresh high-temperature gaskets and O-rings.

    Every overhauled pump undergoes hydrostatic shell pressure testing to 1.5 times working pressure rating and full test-bay performance verification. We partner with plant maintenance teams during planned annual turnarounds across Dahej, Hazira, Vadodara, Ankleshwar, and Ahmedabad. Contact Teflow Pumps on +91 98251 62709 or message our turnaround overhaul desk on WhatsApp to plan your shutdown overhaul campaign.

    Executing a complete industrial pump overhaul during scheduled plant turnarounds ensures rotating machinery operates reliably across multi-year production campaigns without unplanned shutdowns. Teflow Pumps delivers comprehensive industrial pump overhauls for chemical, petrochemical, power generation, and manufacturing facilities across Gujarat, restoring all mechanical and hydraulic clearances to original factory tolerances.

    Our overhaul workflow begins with structured tagging, chemical decontamination, and complete component disassembly. Rotating equipment specialists measure total indicated runout (TIR) on pump shafts, evaluate bearing housing bore concentricity, inspect casing wear ring clearances, and conduct liquid dye penetrant crack testing across impellers and volutes.

    Precision machine shop reconditioning includes line boring of worn bearing brackets, cylindrical grinding of shaft sleeve journals, dynamic balancing of rotating impellers to ISO 1940 Grade 2.5 on computerized dynamic balancers, and CNC machining of replacement wear rings to restore tight 0.25 mm diametrical clearances.

    Wear-sensitive components are systematically renewed with premium industrial parts. We install matched precision angular contact and deep groove ball bearings (SKF/FAG), new single or dual cartridge mechanical seals with chemical-resistant face combinations (silicon carbide, tungsten carbide, FFKM), and fresh high-temperature gaskets.

    Every overhauled pump undergoes hydrostatic casing pressure testing to 1.5 times working pressure rating and test-bay performance verification before return delivery. Contact Teflow Pumps on +91 98251 62709 or message our turnaround overhaul desk on WhatsApp to reserve overhaul capacity today. Turnaround overhaul campaigns feature complete equipment tagging, non-destructive crack testing, shaft sleeve grinding, bearing housing line boring, wear ring renewal, dynamic balancing, and full hydrostatic pressure testing before re-commissioning. Complete turnaround overhauls restore all internal clearances, shafts, bearings, and wear rings to OEM specifications. We provide comprehensive before-and-after documentation dossiers detailing all dimensional and hydraulic test records. Turnaround overhaul campaigns feature complete equipment tagging, non-destructive crack testing, shaft sleeve grinding, bearing housing line boring, wear ring renewal, dynamic balancing, and full hydrostatic pressure testing before re-commissioning. Turnaround overhaul campaigns restore all critical dimensional tolerances, eliminating hydraulic slippage and mechanical vibration to ensure multi-year trouble-free operation across manufacturing complexes. Turnaround overhauls provide complete equipment reliability across multi-year continuous manufacturing campaigns.

    How it works

    Our process

    A disciplined sequence from diagnosis to documented, pressure-tested delivery.

    Step 01

    Shutdown Intake & Tagging

    Pumps are tagged, decontaminated, and completely disassembled for dimensional audit

    Step 02

    Precision Machining

    Shafts are trued, housings line-bored, wear rings machined, and impellers balanced

    Step 03

    Reassembly to OEM Specs

    New precision bearings, mechanical seals, and gaskets are installed to torque limits

    Step 04

    Testing & QA Certification

    Unit undergoes 1.5x hydrostatic pressure testing and performance test-bay validation

    Questions

    Frequently asked questions

    A repair addresses only the failed component (e.g. replacing a leaky seal), whereas a complete overhaul strips the entire pump down, restores all internal clearances, trues the shaft, balances the rotor, and replaces all bearings and wear rings. Complete turnaround documentation dossiers provide full mechanical and dimensional traceability.
