・ PILON
Applications
Large number of installation records at sulfuric acid plant. Generally, such pumps are installed at pit as
submersible pumps, but also as out-of-pit pump exceptionally.
Additionally this pump can be used for strong acid and strong alkaline liquid.

・ Ceramic

Applications
Metal pumps are suitable for transfer stirring of aluminum, zinc, lead, bismuth, tin, molten salt, sodium andpotassium.
Features
These pumps safely replace manual ladling from furnaces with shorter work time, thereby improving the work
environment. The volume of pumping can be adjusted by controlling the rotation speed.

Features
Seal-less structure enables the leakage free. Also it prevents the trouble by cavitation and incomplete pumping.

Description of materials〇 A multi-purpose material resistant for sulfuric
acid solution which has been inherited forgenerations since the foundation of Mazda Pump in
1916.
This material is suitable for handling sulfuric acid,nitric acid, phosphoric acid, chromic acid, andhypochlorous acid, etc.
〇 A corrosion-resistant alloy based on SWEISEN
Sweisen combined withwith the addition of molybdenum, with excellent hydrochloric acid resistance.
