Key features

Manufactured from high-tensile ductile iron (ASTM A536) and vibration-damping gray iron (ASTM A48) for severe industrial duty.

Precision CNC machined mating surfaces and flange bolt holes ensure zero leakage at pressure ratings up to PN40.

Smooth resin-sand cast fluid channels (Ra <= 12.5) reduce hydraulic friction and boost pump operational efficiency by up to 5%.

Horizontally and vertically split casing designs allow fast maintenance and impeller inspection without removing pipe connections.

100% hydrostatic pressure tested and delivered with full EN 10204 3.1 Material Test Certificates (MTC) before dispatch.

Product Q&A

Q:How do I choose between Gray Iron and Ductile Iron for my pump volute casing?

Gray Iron (ASTM A48) is a cost-effective option with excellent vibration damping for standard water supply and HVAC pumps. Ductile Iron (ASTM A536) provides up to 3x higher tensile strength and superior impact resistance, making it essential for high-head pumps, industrial wastewater, slurry handling, or freezing environments.

Q:What is your CNC machining tolerance for flange and bolt-hole positioning?

All mating faces and flanges are machined on large horizontal CNC boring and milling centers. Bolt-hole positional tolerances are controlled within 0.01mm, and parting line flatness is held within 0.02mm, ensuring a 100% drop-in fit with standard ANSI/ASME or ISO piping systems.

Q:Can you manufacture custom volute casings from our technical drawings?

Yes. We provide complete OEM/ODM manufacturing based on your 2D/3D CAD drawings (STEP, IGES, PDF). Our engineers run solidification simulation software before tooling to optimize the casting structure and prevent shrinkage defects.

Q:How do you verify casting integrity and prevent internal defects like blowholes?

Every volute casting undergoes rigorous inspection: 100% hydrostatic pressure testing at 1.5 times the working pressure for 30 minutes. For critical high-pressure applications, we provide optional Ultrasonic Testing (UT) or Magnetic Particle Testing (MT) reports.
