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.

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.

Hydrochloric Acid

Hydrochloric Acid

Problem: Using a reciprocating diaphragm pump creates a turbulent product flow which causes excess vapors and product aeration.

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.

Pharmaceutical

Pharmaceutical

Problem: A leader in the manufacturing of pharmaceuticals uses a Goulds 3196 centrifugal pump size 1x1.5-8 to transfer 35 gallons/minute of acetone at 30 psi from the tank farm into the clean storage room. There is an automatic actuating valve in the line that opens and shuts upon plant demand. This quick shutting valve is sending pipe hammer down the line and causing shaking of the pipes, leaks, pipe hangers pulled from the ceilings, and damage to the pump, resulting in costly, unwanted repairs.

Pulp & Paper

Pulp & Paper

Problem: A major pulp and paper mill in the Northwest used AODD unloading pumps. The reciprocating action of these air operated pumps created violent pulsations that caused both pipe stress and mounting fatigue. In fact, these pulsations often caused the pumps to be pulled from their cement foundations. This created significant downtime, costly foundation repair, environmental hazards, and a dangerous working environment.
