For handling and dispensing of Acids and corrosive liquids, such as Hydrochloric Acid (HCl), Nitric Acid (up to 50%), Dilute Sulphuric Acid (0-60%), Diaphragm Hand Pump in Polypropylene (PP) is used ( Size 1”-25 LPM, Size 1.5”– 50 LPM).  

For Conc. Sulphuric Acid 98% pump in Alloy-20 is used (Size 1”-25 LPM).  

For most of corrosive chemicals, polypropylene is suitable. However, it is advised that details of chemicals, be furnished at enquiry stage itself. Rubber part selection is important, especially for chemicals.

 For all alkalis, pump in PP/SS316 are suitable. These materials are anticorrosive and hence suitable.  

Diaphragm Hand Pumps are also used in the chemical process industry, for occasional sampling / injection / dosing / metering pump duty (manually, approximately).
