VERTICAL PUMP MAINTENANCE
Hydro Pumps specializes in maintaining vertical turbine, deep-well and submersible pumps, from the bowl assembly to the discharge head, including segmented columns up to 30 m. A solid track record in raw water intake, hydroelectric plants and sanitation.
Complete scope for vertical pumps
From rigged removal to aligned reassembly at the discharge head — every stage documented.
Bowl assembly (stages)
Stage-by-stage disassembly, impeller and diffuser inspection, clearance restoration and wear rings for every bowl.
Column and lineshaft
Dimensional inspection of segmented columns up to 30 m, grinding or replacement of lineshafts, sleeves and intermediate bearings.
Discharge head
Head restoration, thrust bearing adjustment and sealing — the point that carries the entire rotating assembly.
Rigging and logistics
Rigging plan, controlled on-site disassembly and tracked transport to our workshop.
Component reconditioning
CNC machining, thermal spray coating and impeller balancing: restoration instead of replacement, at lower cost and shorter lead time.
Reassembly and commissioning
Staged, torqued assembly, final alignment and startup monitoring with vibration checks.
Why vertical pumps demand a specialist
Anatomy of a vertical turbine pump
A vertical turbine pump consists of the bowl assembly (the submerged pumping stages), the column that carries the fluid and houses the lineshaft, and the discharge head that supports the assembly and connects the driver. Every one of those interfaces — intermediate bearings, sleeves, shaft couplings — is a wear point that only shows up at disassembly.
That is why vertical pump maintenance is not a generic service: it demands documented disassembly, dimensional control of every stage, and staged reassembly with specified torque and alignment. A concentricity error in the column becomes vibration at the head and premature bearing failure.
Where we work with vertical pumps
We service vertical turbine pumps in raw water intake for sanitation, cooling and auxiliary systems at hydroelectric and thermal plants, dewatering and pumping in mining, and deep industrial wells.
The service can run entirely at your site — disassembly, restoration of critical components at our workshop, and reassembly — minimizing downtime for the well or intake.
Vertical pump maintenance questions
The most common questions from intake, deep-well and auxiliary system operators.
01Do you disassemble the vertical pump at our plant?
Yes. Our crew handles rigging and on-site disassembly, with every stage documented. Components requiring machining, coating or balancing go to our Várzea Paulista (SP) workshop and return for reassembly on site.
02What is the maximum column length you handle?
We work with segmented columns up to 30 m, typical of raw water intakes and deep wells. Disassembly is done by sections, with concentricity control at reassembly.
03Do you also service submersible pumps?
Yes — vertical turbine, deep-well and submersible pumps from any manufacturer. The scope runs from the bowl assembly to the discharge head, including lineshafts, sleeves and intermediate bearings.
04How long does the intake stay down?
It depends on the scope defined at the teardown inspection. The method (documented disassembly, parallel component restoration and staged reassembly) is designed to minimize downtime. Emergencies get a 24/7 response.
