JHG Specialized Vertical Concentrated Sulfuric Acid Pumps

As the increased concern about energy-efficiency and the dangers inherent in pumping hot concentrated sulfuric acid, JH Pumps supplies JHG specialized vertical concentrated sulfuric acid pumps for heat recovery unit in concentrated sulfuric acid plant based on its prior expertise and decades of experience in field.
Applications
Heating recovery unit at low temperature
To transfer concentrated sulfuric acid where concentration is up to 98.6% and temperature is up to 220℃ at heat recovery unit of concentrated sulfuric acid plant at low temperatures.
Key Characteristics
Capacities: 10 to 3000m³/h
44 to 13200USgpm
Heads: 10 to 40m
32.8 to 131.2feet
Pressures: Up to 1.6Mpa

Features
Patented special alloy for wetted parts
Support structure at drive side: double-row angular contact ball bearing close to drive side balances axial thrust.
Support structure at suction side: one sliding bearing close to suction side withstands radial load. Multiple journal bearings are available if necessary.
Rolling bearing is lubricated by grease refilled straight through a filling port on bearing housing.
Vertical Chemical Pumps's benefits
A specialized new-type mechanical seal assures longer service life due to greater reliability and thermostability.
The sliding bearing is made of high-chromium-nickel alloy with great thermal expansion resistance, which is lubricated by the fluid handled. It ensures smoother operation and a longer wear life.
Grid coupling with accurate alignment, vibration absorption and ease of dismantling and assembly.

ASTM A536 standard

Our ductile iron castings are produced to meet the ASTM A536 standard. This ensures that our customers obtain the engineered properties required for their specific application. All of our castings are created using the latest heat treatment/chemistry design and controls.
Ductile iron, depending on grade, offers different properties. A536 Grade 60-40-18, for example, possesses maximum ductility, excellent machinability and low temperature toughness. A536 Grade 120-90-02, on the other hand, possesses very high strength and wear resistance (though not as wear resistant as our chrome white irons). If your application requires moderate ductility and impact resistance, coupled with high strength, you may want to consider ASTM A536 Grade 80–55–06.
And while we have become an international provider of ASTM A536 ductile iron castings, we also produce several other grades of iron including:
High Chrome White Iron
Gray Irons to ASTM A48 Class 20, Class 30 and Class 40;
Heat Resistant Irons to ASTM A319 Class I Type A, Class II Type A and others;
Nihard Irons
Austempered Ductile Irons (ADI)
Ductile Ni-Resist Irons to ASTM A439 Type D-2 and others.
