Product Description

Replacement Parts Cast Pump Casings for Centrifugal Pump Repairs

Naipu is direct factory of slurry sand pump and wear parts . has own  Foundry workshop, Machining workshop and Assembly workshop.

 

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 the complete pump to satisfy customer's specific requirement.
 

Applications

This alloy meets the requirements for many applications like mining crusher liners, feed-chute liners, apron-feed liners, semi-autogenous ball mill liners, lifter bars, sizing grates, verti-mill liners and slurry pumps.

This alloy is also used in roller crusher applications.  The roller crushers are used to grind coal, limestone, cement, phosphate rock and other soft to medium hard minerals.

Balls in cement clinker mills are another example of where this alloy may be used.

Naipu can produce the spare parts according to the drawing or sample.

Material

Metal Material
 

Code	Material #	Hardness  HRC	Performance	Application
A05	KmTBCr26	≥56	Ranks second only to A07 in abrasion-resistant performance; fair corrosion-resistant performance.	High impact load abrasion condition; PH rate ranging from 5 to 12
A07	KmTBCr15Mo3	≥59	Best abrasion-resistant performance; corrosion-resistant performance is inferior to A05	High impact load abrasion condition
A11	KmTBCrMnMo3	38-42	Mild corrosion-resistant; lower hardness; drilling and tapping operations are applicable.	Fine particles with light abrasion.
A33		≥35	Abrasion-resistant performance is close to A03; fair corrosion-resistant performance	Oxide slurry with PH rate no less than 1, like phosphor-gypsum in phosphate fertilizer plant, nitric acid, sulph-oacid and phosphoric acid, etc.
A49		≥43	Fair abrasion-resistant performance, close to A03; fair corrosion-resistant performance in media with lower PH rate.	Corrosion conditions with low PH rate, especially for flue gas and FGD devices for media of PH≥4; general suitable for lower acid condition.
A12		≥62	Higher abrasion-resistant performance than A05; fair corrosion-resistant performance; suitable for media with PH rate is 6-16, where A05 is not suitable.	High abrasive slurry with fine particles.
A61		63-68	Optimized abrasion-resistant performance than A12	High abrasive slurry with fine particles.

Rubber Material

Material	Material #	Applications
Natural Rubber	R08	R08 is low to medium hardness rubber used for impellers where slurry contains fine particles and erosive.
