DONGGUAN HydroBlue CO.,LTD. supplies precision-manufactured pump hydraulic components to the global industrial market — founded on the understanding that a closed impeller's efficiency advantage depends entirely on the geometric accuracy of its vane profile and the concentricity of its shrouds.
Our 8-member technical team combines practical experience across fluid dynamics, mechanical design and precision casting, electrical power systems, and metrology. This cross-disciplinary capability allows us to evaluate each closed impeller requirement from a complete hydraulic perspective — vane geometry, flow distribution, material behavior, and dynamic balance within the pump assembly.
Research partnerships that strengthen our impeller engineering include:
Send us your ANDRITZ pump model and impeller specifications — our engineering team will confirm the hydraulic profile and provide a formal quotation with material recommendation and confirmed lead time.
Our brand was developed to offer comprehensive solutions for fluid machinery applications internationally — bringing together product supply, system design integration, and on-site technical support through a single accountable channel. The product range we cover includes pumps of various configurations, frequency converters and variable speed drive units, servo positioning controllers, operator interface terminals and programmable control stations, motor control centers and distribution assemblies, AC and DC electric motors, speed-reducing gearboxes, mechanical seal systems and packaged cartridge assemblies, shaft couplings in flexible and rigid styles, and gear-type power transmission equipment. For field assignments, we send our own technical experts to customer locations abroad to execute FARO 3D part scanning for reverse production, precision laser alignment of pump and driver shafts, pump system commissioning and performance testing, and on-site diagnosis and correction of operational issues.
ANDRITZ Closed Impeller is a hydraulic rotating component in which the vanes are enclosed between a front shroud (suction side) and a back shroud (hub side). Unlike open impellers where the vanes are exposed, the closed impeller creates a fully enclosed flow passage from the impeller eye to the vane exit. This enclosed channel minimizes internal recirculation losses and allows the impeller to achieve the highest hydraulic efficiency of any impeller type in clean fluid service.
The front shroud extends from the impeller eye diameter to the vane tip diameter, forming a complete cover over the vane profile. This shroud also serves as the running surface for the front wear ring, where a controlled clearance with the casing wear ring limits internal leakage. Similarly, the back shroud carries the back wear ring running surface and may include balancing holes to equalize axial thrust.
Closed impellers are the most common impeller type in centrifugal pumps handling clean or low-solids fluids, where maximum efficiency is the priority. They are used across process pumps, water supply, chemical transfer, oil and gas, HVAC, and power generation applications.
Our ANDRITZ closed impellers are produced using FARO 3D scanning for vane profile capture, investment or resin sand casting, CNC machining of all critical fits, and full CMM dimensional verification before dispatch.
