We have automated casting production lines, CNC machining center, modern assembly workshops, spray-backing equipment, and large pump testing center.
6 rich-experienced engineers, more than 20 skilled workers with over 10 years working time, and 3 professional QC workers. To ensure that the quality is controlled from the source,and the actual test data is been used as a reliable basis to ensure that every pump and parts meet international high standard requirements.
Performance testing center
To improve the manufacturing technique of traditional large pumps, not choose wooden molds. Pumps below DN600 are all made of metal mold & resin sand, pumps below 3 inches and small parts adopt precision casting,such as wax mold or lost-foam mold. All molds are 3D technology to ensure that good hydraulic models truly transformed into high efficient products.
Make use of the latest computer fluid dynamics analysis Technology(CFD) and advanced hydraulic models home and abroad to truly apply CFD and 3D technology , ensuring that all products are innovative, high-performance, new energy-saving, efficient and reliable products, create more values for customers.
The application of CNC lathes improves the precision of parts processing with higher efficiency.
It has various compensation functions such as linear interpolation and arc interpolation.
Especially win good economic effect during mass production of complex parts .
The introduction of the 6-meter vertical lathe brings great convenience for machining large
dredge pump parts machining.
1)Strictly inspection on each parts to ensure no casing defective and prolong lifetime.
2) Flaw detection and heat treatment on each shaft to ensure tensile and lifetime.
3) Impeller dynamic balance to ensure reliable running.
4) Famous brand bearing with each certification to ensure truth.
5)The End cover, labyrinth cover are coloring zinc plating to ensure high corrosion resistance
and higher international quality.
6) Customized Zinc-plated bolts and nuts to certify zidong pump care on each detailed quality.
7) Dust-free bearing assembly room to extend longer component life.
Modern spray-backing equipment improves paint surface adhesion, uniform thickness, hardness and brightness.
5. Packing and Delivery
Detailed surface treating
Strong enough packing design
Fast transportation line
In past years, we won project bid from U.N; supply china new design 26inch underwater dredging pumps for Qingzhou dredger; hundreds of Cr28 slurry pump for the biggest steel factory in Korea; high chrome alloy OEM spare parts for USA; low base sand gravel pumps for The Netherlands,France ect by our first grade quality and trusted reputation.
