In recent years, India has witnessed double digit growth in specialty chemicals market, especially paint and ink. Paint industry in India was valued at $ 7.8 Bn in 2017 and expected to grow with a CAGR of 12.8% over next five years. Ink manufacturing is also growing at fast pace due to increase in use of packaging materials.

Flammable solvents and viscous fluids are main key raw materials used in manufacturing of paint & coating, and inks. Paint and Ink manufacturer requires sturdy pump design helping them to handle these flammable & viscous liquids. Screw pump can be used to handle these fluids, however it has high maintenance cost associated with it, and take around more time to repair. Stator fails once in 2-3 months and costs around INR 25,000 per month for maintenance (Eg. 3”Pump).

Air Operated Double Diaphragm (AODD) pump is an ideal choice to handle flammable & viscous fluids, as it does not have electrical moving parts (causing no charge), has better clearance, handle’s solid up to 6-9mm and very easy to maintain. AODD pump is portable, making it suitable for tanker unloading application. Self-priming is one of the advantage of AODD and it can work in negative suction lift (5-10 feet) conditions, ideal for process transfer applications. AODD are offered in different MoC’s such as metallic (AL, SS & CI) and Non-Metallic (PP, Conductive PP, & PVDF). Diaphragms are available in variety of materials such as Santoprene, Neoprene, PTFE (Teflon), and Viton; can be selected based on properties of process fluids.
