SULZER Pump Volute Casing

About Dongguan HydroBlue Co., Ltd.

DONGGUAN HydroBlue CO.,LTD. specializes in providing fit-for-purpose solutions in fluid handling, industrial drive systems, and pump engineering. We serve industrial clients who need reliable replacement parts at competitive cost without compromising on quality or delivery reliability.

Our operations are supported by a technical nucleus of 8 engineers and technicians whose combined expertise covers hydraulic design, mechanical fabrication, electrical control architecture, and electronic instrumentation. This multidisciplinary base allows us to handle everything from a single wear part replacement to a full pump system upgrade, with in-house capability to assess, design, manufacture, and test within controlled timelines.

We maintain active technical exchanges with several research institutions:

  • Jiangsu University National Research Center of Pumps — hydraulic profile optimization, CFD analysis, and energy efficiency studies
  • Chinese Academy of Sciences — functional coating research for pump components operating in aggressive media
  • Guangdong University of Technology — automation, frequency conversion, and intelligent pump control systems

OUR BRANDS & SERVICES

We operate under our own technical brand that was established to deliver integrated fluid machinery solutions — combining equipment supply with field engineering and technical consultation under a single accountable supplier. The offering spans pumps, variable frequency drives, servo motion systems, PLC-HMI automation controllers, motor control centers, electric motors and gear reducers, mechanical seals and support systems, shaft couplings, and industrial gearboxes.

For clients who require on-site technical intervention, our team can mobilize overseas to perform FARO 3D laser scanning of worn pump parts for reverse engineering, carry out pump alignment and equipment commissioning, and provide field debugging support — ensuring the installed replacement performs to the original design intent without guesswork.

Product Overview

SULZER Volute Casing forms the stationary pressure envelope of a centrifugal pump. Its primary function is to collect the fluid discharged from the impeller at high velocity and convert that velocity into pressure through the gradually expanding cross-section of the volute passage. The casing also positions the impeller relative to the wear rings, houses the bearing bracket and shaft penetration, and provides the suction and discharge nozzle connections to the piping system.

In slurry and process pump service, the volute casing is exposed to erosive wear from suspended solids, corrosive attack from chemical media, and cyclic pressure loading that can lead to fatigue cracking over extended service life. Wear typically concentrates at the volute cutwater area — the closest point between the impeller tip and the casing wall — where the fluid velocity and turbulence are highest. Flange face corrosion and bearing housing bore wear are also common failure patterns that require replacement rather than repair.

Our SULZER volute casing replacements are produced using FARO 3D laser scanning to capture every hydraulic feature — the volute channel profile, cutwater geometry, bearing housing alignment, and flange bolt pattern — ensuring the new casing restores original pump performance and seals correctly against the casing cover.

Why Choose Our Volute Casings
  • FARO 3D Reverse Engineering — Complete surface scan of the original casing captures volute geometry, cutwater profile, bearing housing bores, and flange details with sub-millimeter accuracy; enables manufacturing from a worn or damaged sample with no drawing required
  • Material Versatility — We cover cast iron, wear-resistant cast iron, cast steel, stainless steel 304/316, duplex SS, and alloy steel — each matched to the fluid conditions and pressure rating of the application
  • 1.5× Rated Pressure Test — Every finished casing undergoes a hydrostatic test at 1.5 times the design working pressure, with written certification provided
  • Dual Casting Capability — Investment casting for thinner-wall stainless steel casings that require superior dimensional consistency; resin sand casting for heavy-section cast iron and steel casings — each method selected for the best trade-off between cost and quality
  • Surface Protection Options — Internal and external coatings available for corrosion protection (epoxy, zinc-rich primer), wear resistance (hard chrome, rubber lining), and general anti-rust finish (black oxide)
  • Direct Bolt-On Fit — No adapter plates or modifications needed — mounting dimensions, flange patterns, and internal clearances replicate the OEM standard exactly
