Reliable Rosin Size Dosing

Reliable Rosin Size Dosing

Problem: A pulp and paper facility required highly accurate and reliable rosin size dosing as part of its pulp treatment process. The application demanded precise chemical control to ensure consistent paper quality, while also providing uninterrupted operation in the event of pump maintenance or failure.

Given the critical nature of rosin sizing, the customer needed a fully integrated dosing system that could deliver accuracy and reliability throughout continuous operation.

Deionized Water Dosing in R&D Lab

Deionized Water Dosing in R&D Lab

Problem: As it is a system with 8 units, the deionized water requirement can range from one unit at a time to all 8 simultaneously. The pump pulse was damaging the flow sensors, and the pressurized line was disrupting the solenoid valve cycle. When the water requirement was low or from only one unit, the pump tended to shut down.

Pulsation in Sulfuric Acid Feed

Pulsation in Sulfuric Acid Feed

Problem: MID South Wire Co., Inc. in Nashville, TN uses Yamada Air Operated Double Diaphragm Pumps to supply the feed of sulfuric acid to the centrifuge which is a continuous process and requires as smooth and even a flow rate as possible. The double diaphragm pump was giving good service, but the customer either had to change out the pump for one with continuous flow or find a solution for the pulsation.

Deep Well Injection

Deep Well Injection

Problem: Hydroplex HP-350 triplex plunger pump (0.75 gpm at 10,000 psi) for high pressure deep well methanol injection in an oil & gas upstream pumping application. On the discharge side of the pump, the amount of methanol the pump is dosing is metered. Without a dampener to control pulsations and smooth out the flow, the installed flow meters will not give accurate readings. Additionally, when using a triplex pump it is important that all three chambers of the pump stay full of fluid with no voids. Any voids or pockets can cause seals to leak, pump vibration and excess pump noise.

Aeration and Pulsation of Cleaning Products

Aeration and Pulsation of Cleaning Products

Problem: Pumping household cleaning products such as oven cleaner, furniture polish, floor waxes, and starch. After blending of various chemicals to manufacture the final products, the product is pumped into various holding tanks within the plant. During this process the product travels through long lengths of piping to various filling locations. Foaming and aerating of the various cleaning products created a problem with the filling process of aerosol cans. Also, due to the long lengths of piping, the pumping action of the diaphragm pump created pipe vibration and potential leaks at fittings.

Filling Hose Failure due to Pulsation

Filling Hose Failure due to Pulsation

Problem: Blacoh was contacted by a large manufacturer of bulk chemicals. They use air operated diaphragm pumps (AODD) to load chemicals into tanker trucks through a 20' flexible 3" reinforced hose that lies on a concrete floor. The pulsation generated by their AODD pumps caused the hose to shake back and forth, scuffing the hose on the concrete floor and causing "hose abrasion". Ultimately, these hoses would fail from abrasion due to the scuffing action. This failure meant considerable downtime, lost product, extensive cleanup, and hose replacement, all of which came with an associated cost.
