Waste Liquids

Waste Liquids

Problem: A large manufacturing plant located in Japan uses air operated high pressure injection pumps throughout their plant to pump out waste liquids from reactor vessels. The reciprocating action of the pumps creates a pulsating flow which vibrates the plumbing, producing loud noise resulting in worker complaints and possible safety issues.

Decontamination

Decontamination

Problem: A decontamination facility pumped acids and water through a series of 15" spray nozzles to rinse radiation from contaminated metals. However, the pulsating action of their reciprocating pumps caused uneven spray into the rinse tanks, and the metals were not rinsed completely.

Descaling

Descaling

Problem: Rocky Mountain Steel Mills in Pueblo, CO uses two Myers/Aplex MA-240M quintuplex 200 HP plunger pumps to descale the raw material before it is sent through the forming rollers that create the final product. Each of these pumps produces 100 GPM at 2,200 psi. The reciprocating action and high pressure created by these pumps causes severe shaking of the pipes, valves, and pipe supports in the system. More critical to the operation, the pulsating flow can cause erratic descaling of the raw material. This erratic descaling can cause damage to the form rollers and can make it difficult for the steel mill to achieve consistent quality in their final product. This style of pump also requires a smooth flow of fluid to the inlet to work properly.

Advanced Materials Facility

Advanced Materials Facility

Problem: An advanced materials facility based in the Greater Toronto Area was hesitant to include dampeners in their operation as they hadn't had luck with them previously. Blacoh asked to see the installation. Upon further investigation, we discovered the customer had one uncharged dampener for two pumps (photo below), and it was located well outside the recommended 10 pipe diameter rule. This is a prime example of the importance of Size, Location, and Charge in regards to dampener installation.

Facilities Maintenance

Facilities Maintenance

Problem: Our customer moved into their new building which did not have a pressure reducing valve in the water main and the system pressure in the building was around 90 psi. The owner's office is near the men's restroom. Every time the urinal was flushed, extreme water hammer occurred. This was very aggravating to the owner and he was afraid that the water hammer might cause a pipe to rupture and flood the building.

Paper Industry

Paper Industry

Problem: A leading paper manufacturer located in Japan uses air operated double diaphragm (AODD) pumps to inject process chemicals into a mixing tank. The low viscosity of the liquid, less than 10 centipoises, makes the chemical in this particular application very susceptible to the reciprocating action of the pumps. This makes it extremely difficult to maintain any type of accuracy when introducing the chemical into the batch. As a result, the quality and consistency of the final product suffers.
