FLYGT High-Precision Investment Casting Volute Casing with Stainless Steel Material for Submersible Pump Systems

Our brand was established to deliver comprehensive technical solutions across the fluid machinery and engineering sectors. Our offerings include industrial control and drive equipment, mechanical seals, and international field engineering services.

With a complete suite of specialized technologies and product brands, we provide clients with expert technical guidance, commercial support, and integrated product solutions — from pumps and frequency converters to servo drives, PLC-HMI, industrial control cabinets, motors, mechanical seals and assemblies, couplings, gearboxes, and full-cycle engineering services (overseas on-site 3D scanning reverse molding of pump replacement parts and equipment debugging by our engineers deployed internationally).

Ordering a replacement FLYGT volute casing is straightforward:

1. Submit Inquiry — Provide pump model, casing part number, or high-resolution photographs of the worn component from multiple angles
2. Technical Review — Our engineers verify dimensions, material, pressure rating, and flange configuration within 24 hours
3. Quotation Issued — Formal quotation covering unit price, casting tooling cost (if applicable), surface treatment options, and lead time
4. Sample Approval (Optional) — Sample casting produced for dimensional inspection and hydrostatic testing before batch production
5. Production & QC — Manufacturing commences upon deposit; NDT, dimensional inspection, and hydrostatic test included
6. Dispatch & Tracking — Shipment after balance payment; CMM report and material certificates included in documentation

Beyond volute casings, we supply the full range of FLYGT pump spare parts:

Every volute casing undergoes rigorous multi-stage quality verification:

1. Material Certificate — Mill certificates for raw casting material against ASTM, DIN, EN, ISO, TOCT standards
2. Visual & Dimensional Inspection — Initial dimensional check against CAD model; critical features identified for CMM measurement
3. Non-Destructive Testing — RT (Radiographic) and UT (Ultrasonic) for internal casting soundness; MT (Magnetic Particle) and PT (Penetrant) for surface and near-surface defects
4. Hardness & Roughness Testing — Verifies material hardness and internal surface finish quality of the volute channel
5. CMM Dimensional Report — Full 3D coordinate measurement of discharge flange, mounting faces, and critical hydraulic geometry
6. Hydrostatic Pressure Test — Water pressure held at 1.5× rated working pressure for 30 minutes; no leaks or permanent deformation permitted

Certifications: ISO9001:2015, ISO14001:2004, API Specification Q1.

Volute casings are large, heavy castings requiring robust export packing:

• Anti-Rust Treatment — Internal and external surfaces coated with rust-preventive compound before packing
• Foam & Bubble Wrap — Heavy-duty foam pads and bubble wrap on all critical machined surfaces and flange faces
• Wooden Crate — Heavy-duty plywood crate (ISPM 15 compliant) sized for the casing with adequate internal bracing and blocking
• Custom Packing — Available with customer-specific labeling, serial number marking, or export documentation formatting

Lead Time: 30 days after deposit. Complex geometries or special alloys may require 45–60 days.

Shipping: Sea freight (standard), Air freight (urgent), Land transport (neighboring countries).

Payment: 70% T/T deposit, balance against copy of B/L. L/C accepted for qualified buyers.
