API OH1 OH2 Chemical Pump



Chemical pump


Pumps are single stage. horizontal,radically split volute pump. The Casing is centerline supporting and equipped with single radically impeller. Axially inlet and radically outlet.The pump adopt wear ring and balancing hole to realize the hydraulic balance,Shaft seal adopts AP1682 Standard mechanical seal and flushing plan.Standard  piping design in accordance with API standard. which can cooling the centerline supporting pump .The suction flange rating pressure grade is the equal to discharge flange. Pumps rotation is clockwise viewed from motor end.

Medium transfer Liquid:

Organic acid and inorganic acid,such as sulfuric acid ,hydrochloric acid and phosphoric acid, etc ,Alkaline solution of various concentrations of sodium hydroxide and sodium carbonate.All kinds of liquid petroleum products,organic and other corrosive materials and products .
