c.E-Glass fiberglass is selected as reinforced material to improve the compression resistance, fatigue resistance and deformation resistance of the products. 

d.The embedded ring ensures that the fibrous tissue of the housing cannot be damaged mechanically, and improves the smoothness and convenience of the installation of end assembly. 

e. LZRO/BALANCE series of products adopt high grade automobile baking varnish craft to ensure the smoothness and brightness of the product surface. 

Chemical Properties：

a.Adopt epoxy resin system, which has excellent corrosion resistance, anti-aging property, high temperature resistance, and oxidation resistance of the products. 

b.The advanced technology ensures the stability of products.

Spare Parts of The Membrane Housing

1) Technology  

a.The bearing plate adopts aerial processing craft which efficiently improves the intensity and capacity to resist deformation.

b.Seal kit adopts special structure and technique which efficiently enhances the leak tightness, anti-aging and simple assembly and dis-assembly.

c.The three-turning locking ring which is designed according to the human body mechanics for easyinstallation and removing.

2)Materials

a.Bearing plate is made of aluminum alloy to enhance the intensity and improve the feature of resisting deformation.

b.Sealing elements adopt environmental-friendly material to assure the tightness and high water quality, as well as to improve its anti-aging capacity.

c.Feed /concentrate port adopt SS316L with high quality to assure outstanding anti-corrosion property and convenient maintenance.

d.Provide professional choice of material for special industries.
