1. The Challenge of "Big & Precise":
In the world of industrial fluid handling, manufacturing large-scale pump components is a test of a factory's true strength. Procurement managers often face a dilemma: foundries that can cast big parts often lack precision machining, while machine shops lack the capacity for massive castings.
At Dalian Jiachuang Metal Manufacturing Co., Ltd., we solve this by integrating heavy-duty manufacturing under one roof.
2. Unleashing the Power of Gantry Milling:

Our confidence comes from our hardware. As shown above, our facility is equipped with industrial-grade 5x6m and 4x5m CNC Gantry Milling Machines.
Why does this matter?
Capacity: We can handle workpieces weighing tons with diameters exceeding 4-5 meters.
Stability: These rigid machines ensure that even when removing heavy stock from cast steel, the vibration is minimized, ensuring tight tolerances.
3. Case Study: BB1 & BB2 Split Casings:

Real-world application is the best proof. The photos above show our recent production of BB1 (Axially Split) and BB2 (Radially Split) pump casings.
The BB1 Advantage: For axially split casings, the sealing surface flatness is critical. Thanks to our large gantry mills (shown in the previous section), we machine the entire split surface in a single setup. This guarantees perfect alignment between the upper and lower halves, preventing leakage under high pressure.
The BB2 Precision: For multi-stage BB2 casings, internal concentricity is key. Our machining process ensures the bearing housing and seal chambers are perfectly aligned.
4. From Pattern to Final Product:

Look at this 1.4m caliber double suction pump ready for shipment. A part this huge starts with a precise pattern.
Our in-house Large Component Pattern Workshop allows us to build the skeleton of these giants rapidly. Unlike factories that outsource patterns, we control the shrinkage rates and machining allowances from the very beginning, ensuring the final cast steel casing fits our machine tools perfectly.
From the Various types Mold workshop to the heavy gantry mill, and finally to the finished BB1/BB2 casings, we control every step. Send us your drawings for heavy-duty pump parts, and let our capacity work for you.
We are actively expanding into overseas markets. If you have any product requirements, please feel to contact our customer service team. If you have any questions about our product range or specifications, please leave a message (we can custom-manufacture 99% of cast steel pump parts).
