Chemical Feed

Chemical 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 pulsating flow.

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.

Cleaning Products

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.

Tank Truck

Tank Truck

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.

Filter Press

Filter Press

Problem: The Franklin Brine Treatment Plant uses a Wilden diaphragm pump to charge a filter press with brine water oil/sludge. When first charging the filter press with the diaphragm pump, the filter screens are clean and product flow is exceptionally fast. Because of the reciprocating design of the pump, product flow is pulsating. The pulsating flow produces pressure spikes which cause damage to the filter screens. The piping is CPVC plastic because the brine water is corrosive. The pulsating flow also causes vibration which results in leaky pipe joints.

Coating Filtration Line

Coating Filtration Line

Problem: A painting operation for a skid manufacturer in North Carolina uses a large quantity of bag filters throughout the paint line to filter rinse water and various coatings and paints. Paints and coatings were clogging the gauges causing the gauges on the bag filters to give false readings. The incorrect gauge readings led to poor filtration, due to infrequent bag changes, and manufactured parts were getting rejected in QC.
