OEM Spare Parts

We can provide OEM( original equipment manufacturer) service and ODM(original design manufacturer) service.

For our OEM and ODM production services, we provide in-house planning, processing drawing creation and sample production. Once customer approval is received we then source the materials and carry out production at our factory.
 
At NAIPU, we hold the responsibility to perform checks to guarantee that all specifications are followed, that quantities match the order, and that the production setup is optimized.

We have supplied many OEM and ODM products successfully to our clients, such as OEM JC pumps and spares,OEM high chrome pump and spares,OEM Alloy 20 pump parts,OEM Hastelloy pump parts etc for mining machinery with good quality and price according to customers' drawing or samples .

We are also a single-source OEM supplier,If the clients ask us to produce their products,and they has exclusive right of these OEM products,and we can't provide them to other clients.

Based on many years' rich experience in slurry pump manufacturing and design,NAIPU not only provide OEM customization service for various pump spares, but also do the OEM/ODM service for  other wear parts  to satisfy customer's specific requirement.


Foundry workshop

Casting is an important process in the production process of slurry pump parts. It is necessary to strictly control the material ratio, casting temperature, and different heat treatment methods for different material requirements. During this process, Naipu will cast test blocks, use a spectrometer to test the chemical composition of the material, and analyze the metallographic structure of the metal alloy with an optical microscope, and use feedback to improve the corresponding production quality. The casting capacity ranges from 0.5KG per unit weight to 15 tons.



Machining Workshop

Machining includes various vertical and horizontal machine tools, CNC machining centers, static and dynamic balancing machines, various measuring tools and fixtures.The high chromium alloy itself has high hardness, and there are strict regulations on the tool and the operator's experience during the processing. Otherwise, it will have a high rejection rate. In this regard, all Naipu's operators have more than 10 years of experience in the industry, through quality management, using MT, PT, UT, RT non-destructive testing methods, the quality of every spare part is guaranteed. 



Assembly workshop

The assembly of each pump has undergone strict data testing to ensure safe and stable use by users. In addition, users can choose to install some subsystems according to actual needs, such as cooling system, bearing lubrication system, temperature measurement system, power control system and so on.In terms of product after-sales, the inventory of vulnerable parts is sufficient, and the after-sales team responds in a timely manner. A global after-sales service contact mechanism has been established to ensure that users can solve problems in the first time
