Kenda Pump is a professional provider of slurry pump OEM and custom parts services. We support custom machining according to drawings, reverse engineering and modeling. Whether for non-standard sizes or special alloys (such as CD4MCu and Hastelloy), we can provide you with high-precision, 100% matching customized solutions to help optimize equipment performance and reduce spare parts costs.
We not only manufacture standard parts, but also are committed to solving the "non-standard" challenges you face under extreme or special working conditions:
Manufacturing by Drawings: Perform precision casting and mechanical machining strictly in accordance with your technical drawings.
Reverse Engineering: For obsolete pump models that are no longer in production or lack original drawings, we use 3D laser scanning and mapping to achieve 1:1 restoration and optimize the dimensions of spare parts.
Performance Retrofit: Adjust the impeller blade angles or the thickness of the casing liner based on actual working conditions to enhance efficiency or extend wear life.

In addition to standard high-chromium alloy and rubber materials, our OEM services support a wider range of materials designed to withstand extreme acidic, alkaline, and highly corrosive environments:
Material Category | Common Code/Grade | Core Characteristics | Typical Applications |
Duplex Stainless Steel | CD4MCu, SS316, SS304 | Corrosion resistance combined with moderate wear resistance | Phosphorus chemical industry, Desulfurization conditions |
High-Nickel Alloy | Hastelloy | Excellent resistance to strong acid and strong base corrosion | Chemical industry, Salt chemical industry |
Special Carbide | A49, A33, A07 | Extreme hardness for specific pH values | Corrosive slurry transportation |
Ceramic Composite | Ceramic Inserts | Extreme wear resistance; hardness far exceeds metal | High-concentration abrasion conditions |
The essence of OEM parts lies in "precision." We ensure the perfect fit of parts with your pumps through the following processes:
Spectral Analysis: Before each tap of molten iron, spectral analysis is conducted to guarantee that the content of alloying elements accurately meets the required specifications.
3D CMM Inspection: Coordinate Measuring Machines (CMM) are used to inspect critical dimensions (such as axial positioning and mating tolerances), with error control at the micron level.
CFD Fluid Simulation: For performance-enhanced parts, Computational Fluid Dynamics (CFD) simulation is performed before production to ensure that the modified impellers achieve the desired flow rate and head.
Customized Branding: Specific part numbers, logos, or serial numbers can be cast or laser-marked on the parts according to customer requirements. (Neutral packaging is available for agents.)
Export-Grade Protection: For precision-machined surfaces (such as sealing surfaces and threads), we apply multiple layers of anti-rust oil and perform vacuum sealing to ensure no rust or damage during overseas transportation.
Q: I don't have drawings, only worn-out or damaged parts. Can you still handle this?
A: Absolutely. Our engineers can use a portable 3D scanner to perform reverse modeling on the damaged parts. Through algorithmic compensation for worn areas, we can restore them to their original dimensional design.
Q: What is the Minimum Order Quantity (MOQ) for OEM parts?
A: For custom parts, we understand the need for research, development, and testing. We accept small batch orders or even single-piece orders.
Q: How do you ensure that the chemical composition of custom materials meets the standards?
A: We provide a Material Certificate and a third-party NDT (Non-Destructive Testing) report (if required) with each shipment. Every batch of products is assigned a unique Heat Number, ensuring full traceability throughout the process.
