About Kingda
Slurry Pump Manufacturing Capabilities
Kingda Pump Group manages the critical stages of slurry pump production in-house—from process review and CNC pattern making to alloy casting, heat treatment, machining, rubber lining, dynamic balancing, assembly, and performance testing.
This integrated workflow gives engineering, production, and quality teams direct control over key specifications and inspection points for standard pumps, large units, special materials, and custom projects.

Vertically Integrated Manufacturing
Key production stages are coordinated by in-house teams, linking approved design requirements, material specifications, machining dimensions, inspection records, and final test results.

Consistent Quality
Critical processes are controlled in-house, reducing variation between suppliers and production batches.

Faster Customization
Engineering, casting, and machining teams work directly from approved operating data and drawings.

Traceable Production
Material, heat-treatment, inspection, balancing, and test records can be linked to the order and component.

Reliable Delivery
Integrated planning supports batch orders, phased deliveries, and ongoing spare-parts supply.
From Production Drawing to Final Delivery
Each pump and critical component follows a defined sequence of preparation, manufacturing, inspection, and verification before shipment.

1. Production Planning and Process Review
Before production, engineering and process teams review flow, head, slurry properties, solids, corrosion, materials, interfaces, inspection points, and test requirements. For large or first-of-kind components, manufacturability is confirmed before release. Learn more about Kingda’s pump engineering and material technology.

2. Pattern and Mold Making
CNC equipment and a dedicated wood-pattern machining center are used to produce patterns for pump casings, impellers, liners, and other wear components. Critical dimensions, machining allowances, parting lines, and surface condition are checked before molding.

3. Material Preparation and Casting
Kingda performs melting, resin-sand molding, pouring, and initial cleaning in-house. The foundry operates six continuous sand mixers, including units rated up to 40 t/h, two 25 t/h automatic sand-treatment lines, and direct-reading spectrometers for pre-pour chemistry verification. Maximum single-casting weight is 20 tons.

4. Heat Treatment
Pit-type tempering, box-type, and bogie-hearth furnaces support softening, hardening, tempering, and other controlled processes. Hardness and microstructure can be verified after heat treatment to confirm material condition before machining.

5. Cleaning and Casting Inspection
- Sand removal, shot blasting, and grinding
- Visual and initial dimensional inspection
- Casting-defect evaluation
- Non-destructive testing when specified
- Nonconformity handling and re-inspection

6. Precision Machining
More than 100 metal-cutting machines support turning, milling, boring, drilling, and grinding of pump casings, impellers, liners, shafts, and bearing assemblies. Selected equipment includes large vertical lathes, floor-type boring mills, a 3,500 mm vertical turn-mill center, and a 3,000 × 8,000 mm CNC gantry drilling-milling machine.

7. Rubber and Special Lining
Dedicated lining capabilities support metal-surface preparation, bonding, molding, vulcanization, and dimensional inspection. Rubber, polyurethane, and ceramic solutions are applied where specified for the product and service conditions. Explore our rubber-lined slurry pumps and ceramic slurry pumps for abrasive and corrosive applications.

8. Dynamic Balancing and Pump Assembly
An HL-16000 hard-bearing vertical balancing machine performs dynamic balancing on impellers weighing up to 16 tons. Final assembly includes bearing installation, shaft alignment, impeller-clearance adjustment, seal installation, fastening checks, and rotational inspection.

9. Performance Testing
Kingda operates a large-scale pump testing facility. Current facility limits include 20,000 m³/h flow, 1,200 m head, and 3,000 kW test power. Depending on pump type and order requirements, the test scope may include hydraulic performance, hydrostatic pressure, vibration, noise, bearing temperature, and leakage checks.
- Flow, head, efficiency, and power testing
- Hydrostatic pressure testing
- Vibration and noise checks
- Bearing-temperature monitoring
- Leakage inspection
- Performance curves and test records, when specified

10. Painting, Packaging, and Shipping
After final inspection, products are prepared for service and transport through surface treatment, protective coating, marking, rust prevention, and export packaging. Heavy pumps and parts are secured according to weight, dimensions, and transport method to reduce the risk of impact, corrosion, and moisture damage.
Quality Control and Traceability
Quality controls are applied from incoming materials through casting, heat treatment, machining, balancing, assembly, and final testing. Available inspection equipment includes spectrometers, carbon-sulfur analyzers, gas analyzers, hardness testers, metallographic microscopes, and surface-roughness instruments.
