MAINTENANCE & PARTS FOR SULZER PUMPS
Sulzer pumps equip the heaviest processes in Brazilian industry — pulp and paper, mining, oil and chemicals. Hydro Pumps repairs this equipment and supplies compatible components with the rigor process pumps demand: certified materials, design clearances and documented testing.
Hydro Pumps is an independent maintenance and parts supply company, with no commercial affiliation to Sulzer. The brand cited belongs to its respective owner and is mentioned exclusively to indicate application compatibility.
What we service in the Sulzer fleet
Process and severe-service pumps — complete repair and compatible replacement.
Process pumps
Inspection, restoration and testing for chemical, pulp and paper and O&G process pumps.
Stock and slurry pumps
Impellers and components for the severe service of pulp and mining, with abrasion-resistant materials.
Compatible impellers
Restoration or manufacture to drawing via reverse engineering — balanced to G2.5.
Process sealing
Single and dual seals and seal plans suited to the fluid and criticality.
Wear parts
Rings, bushings, shafts and liners in alloys equal or superior to the originals.
Discontinued lines
Orphaned components reproduced via reverse engineering from the used part.
Process rigor, independent agility
Process pumps accept no generic repair
A stopped process pump halts the whole plant — and a poor repair stops it again within months. Our workshop treats Sulzer equipment with process discipline: documented inspection, certified materials, clearances restored to design and performance testing before return.
For aggressive fluids and abrasive service, we apply alloys and coatings selected for the actual application — not for the original part's appearance.
A real alternative to the factory queue
Imported components mean long lead times and exchange rates. We manufacture compatible parts in our own machining shop from reverse engineering — impellers, rings, shafts, bushings — with lead times sized by your operation's criticality.
Each part ships with dimensionals, raw material certificates and, for rotating parts, documented G2.5 balancing.
Sulzer pump maintenance questions
What process plants ask before contracting.
01Do you repair Sulzer stock pumps for pulp and paper?
Yes — stock and liquor pumps are a relevant part of our work in the sector: restoration of special impellers, clearance restoration, sealing suited to fiber service and bench testing before return.
02Can you manufacture a part for an imported Sulzer pump?
Yes — via reverse engineering: we measure the used part (even worn), rebuild the drawing and manufacture in an equal or superior alloy. It is the alternative to import lead times and costs, with dimensionals and certificates in the dossier.
03Do you service Sulzer pumps at O&G and chemical units?
Yes — with those sectors' requirements: repair with reference to API 610 practices where applicable, dual sealing for hazardous fluids and complete documentary traceability of materials and tests.
04What if my pump's line was discontinued?
That is the classic reverse engineering case: we reproduce the components from the existing parts and restore technical support to the equipment — without depending on the manufacturer's remaining stock.
