In recent years, India has witnessed integer growth in the specialty chemicals market, especially paint and ink. The paint industry in India was valued at $ 7.8 Bn in 2017 and expected to grow with a CAGR of 12.8% over the next five years. Ink manufacturing is additionally growing at a fast pace thanks to the increase in the use of packaging materials.
Flammable solvents and viscous fluids are the main key raw materials utilized in the manufacturing of paint & coating, and inks. Paint and Ink manufacturer requires sturdy pump design helping them to handle these flammable & viscous liquids. Screw pump is often wont to handle these fluids, however, it's high maintenance cost related to it and take around longer 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 a perfect option to handle flammable & viscous fluids because it doesn't have electrical moving parts (causing no charge), has better clearance, handle’s solid up to 6-9mm and really easy to take care of. AODD pump is portable, making it suitable for tanker unloading applications. Self-priming is one among the advantage of AODD and it can add negative suction lift (5-10 feet) conditions, ideal for process transfer applications. AODD are offered in several MoC’s like metallic (AL, SS & CI) and Non-Metallic (PP, Conductive PP, & PVDF). Diaphragms are available in sort of materials like Santoprene, Neoprene, PTFE (Teflon), and Viton; they are often selected supported properties of process fluids.

Pumping Abrasives on a replacement All-Flo pump
Secondly, let's assume that your plant is converting from Antlia Works or Yamada Air Operated Diaphragm Pump over to All-Flo Water pumps. The 1.5" Antlia Works AODD worked okay, but had more energy consumption (in CFMs) and therefore the Total Cost of Ownership (TOC) was beginning to increase. you made the decision to offer the 1.5" chrome steel All-Flo a try. Your fluid is extremely abrasive and caustic but didn't cause any issues together with your previous Antlia Works pump. Now, that you've got installed the new All-Flo pump, you're seeing a decrease in performance.
Your Maintenance Manager brought this to your attention, and you create a call to your pump distributor. one of the Sales Application Engineers (SAE) at your distributor begins to ask a couple of questions. You mention that your Antlia Works pump achieved 120 GPM at 80 PSIG, but you wanted increased efficiency, which is why you switched to the All-Flo pump. Your distributor's SAE asks what flow (or fluid velocity) you now have at 80 PSIG. You say it wont to be 155 GPM when the pump was new, until the recent plummet inflow. Next, the sales engineer asks about the chemical makeup of the fluid and what sound the All-Flo pump is currently making. You say it's a knocking, clanking sound mid-stroke, and sounds somewhat off-kilter or asymmetric, but it didn't always sound this manner . After some more discussion, the sales application engineer asks you to require off the upper manifold and inspect the ball valves.
After shutting off the air, closing the fluid suction valve, slightly opening the air valve to flush out any fluid then immediately closing it, and eventually closing the fluid discharge valve, you are able to disassemble the pump. In but 20 minutes, you've got the upper manifold (fluid discharge manifold) off, and you realize that the balls and seats are disfigured, thus not sealing properly. One ball especially is considerably smaller, showing signs of corrosive decay. You consult your Maintenance Manager and he says this shouldn't happen since the balls are made from PTFE and were chosen precisely because they're immune to your particular abrasive fluid. However, after another brief call to your Sales Application Engineer, you discover out that a rise in fluid velocity (flow rate) will cause abrasive fluids to be exponentially more caustic. we do not have space during this article to elucidate the algorithms for acetic properties supported fluid velocities, but this is often clearly the matter is during this scenario.
