ANDRITZ Pump Casing – Casting Process, Quality Inspection & How to Order
About Dongguan HydroBlue Co., Ltd.
DONGGUAN HydroBlue CO.,LTD. is a full-service engineering supplier of pump stationary components to the global industrial sector — operating on the principle that the quality of a pump casing determines the structural integrity and hydraulic efficiency of the entire pumping system for years of operation.
Our technical staff of 8 professionals combines practical expertise across hydraulic system design, mechanical foundry technology, electrical engineering, and non-destructive inspection. This integrated capability allows us to manage every stage of casing production — from pattern making and material selection through casting, heat treatment, machining, pressure testing, and final coating.
Institutional research partnerships that support our casting engineering include:
Jiangsu University National Research Center of Pumps — hydraulic design and volute optimization for slurry and process pumps
Chinese Academy of Sciences — protective lining materials for abrasive and corrosive casing service
Guangdong University of Technology — industrial automation and intelligent drive systems
Contact us with your ANDRITZ pump model and casing requirements — our team will verify the specification and provide a formal quotation with material options, lining recommendations, and delivery schedule.
OUR BRANDS & SERVICES
Through our brand we provide a single source of accountability for fluid machinery solutions — combining component supply, system integration, and international field services. The product range includes pumps, frequency converters, servo drives, PLC-HMI platforms, motor control cabinets, electric motors and gearboxes, mechanical seals and assemblies, couplings, and gear transmissions. Field services include overseas FARO 3D scanning, laser alignment, pump commissioning, and on-site debugging by our own engineers.
Casting & Manufacturing Process
3D Scan & Reverse Engineering — FARO arm captures internal volute/diffuser profile, flange bolt pattern, register fits, and wall thickness distribution from existing casing
Pattern Development — CNC-machined pattern, core boxes, and gating system designed with shrinkage and draft allowances for the chosen casting method
Molding & Core Assembly — Resin sand or V-process mold with internal cores defining the volute flow passage; core position verified before closing
Melting & Pouring — Induction furnace charge with spectrographic chemistry verification; pour temperature and rate controlled for defect prevention
Shakeout & Cleaning — Casting cooled, shaken out from mold, and cleaned with shot blasting or grinding
Heat Treatment — Stress relief (cast iron), normalizing + temper (steel), or solution anneal (SS) per material specification
Hydrostatic Pressure Test — Casing pressurized to 1.5× working pressure; hold time per API or customer specification
Final Surface Treatment & Dispatch — Internal lining (epoxy/rubber/polyurethane), external prime + topcoat, packing for sea freight
Quality Inspection
Hydrostatic Test — 1.5× maximum working pressure; 30-minute hold with no leakage or visible deformation
3D CMM Verification — Volute profile, flange dimensions, register bore position, bolt pattern, and wall thickness checked against scanned model
NDT — Radiographic examination for internal soundness (pressure-containing sections); ultrasonic wall thickness mapping; magnetic particle or dye penetrant for surface defects at machined sealing faces
Material Certification — Chemical composition report and mechanical test results from production coupons; heat treatment records
Hardness Testing — Brinell on machined surfaces confirms material grade and heat treatment quality
Certifications: ISO9001:2015, ISO14001:2004, API Specification Q1.
How to Order
Pump Model & Serial Number — Quickest route to correct casing specification
Or Provide Sample Casing — Ship the existing casing for FARO 3D scanning; casting can be produced to match exactly
Material & Lining — Base material per specification; internal lining requirements (epoxy, rubber, polyurethane)
Flange Standard — ANSI 150/300/600, DIN PN10/16/25/40, or other flange drilling standard
Delivery — 40–60 days after deposit (iron/steel); 60–80 days (SS or high-alloy)
Payment: 70% T/T deposit, balance against copy of B/L. L/C available for qualified buyers.
