Wastewater Sludge Pump Pulsation

Wastewater Sludge Pump Pulsation

Problem: The City of Colorado Springs WWTP uses Abel mechanical double diaphragm pumps to transfer sludge throughout their facility. The pump is ideal for their application due to the solids handling capability, and the fact that the pump is a positive displacement pump which allows the flow to be metered. The reciprocating action of the pump causes excessive pulsation in the discharge piping. The constant pulsation has caused broken pipes, failed gaskets, damaged valves, and has pulled pipe supports from foundations.

Bottling Line Water Hammer

Bottling Line Water Hammer

Problem: A manufacturing facility in Arizona producing bottled cleaning chemicals was operating a high cycle filling system running 24/7. The process used a circular bottling machine with a fill box controlled by a quick closing valve, which repeatedly opened and shut to fill batches of 20 bottles at a time.

Each time the valve closed, it generated a severe water hammer event, sending pressure transients back through approximately 100 feet of piping to the pump. These repeated pressure spikes caused extreme pipe shaking to the point where operators avoided standing near the piping due to safety concerns.

The ongoing stress raised serious risks, including:
• Potential pipe failure
• Chemical spills onto the plant floor
• Possible exposure hazards to nearby personnel

Tool Manufacturing Manifold Startup Shock

Tool Manufacturing Manifold Startup Shock

Problem: An internationally known tool manufacturer located in the Pacific Northwest was experiencing severe pipe vibration in an overhead manifold system. The system delivers coolant to several production grinding machines. The coolant is delivered to the manifold by a 300 gpm centrifugal pump located in a reservoir on the plant floor. When the pump is started, a ball valve at the pump discharge is opened and fluid is pushed vertically up to the horizontal manifold. The manifold does not stay filled with liquid during idle periods so, when the pump is started the coolant flowing into the manifold must first push the air trapped in the manifold out the machine coolant nozzles before coolant reaches the machines. Since air moves more quickly out of the nozzles than liquid, when the coolant reaches the nozzles the velocity of the coolant is instantly reduced and a water hammer effect occurs creating severe pipe vibration.

Commercial Restroom Flush Water Hammer

Commercial Restroom Flush Water Hammer

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.

Resin Plant Drum Filling Water Hammer

Resin Plant Drum Filling Water Hammer

Problem: MeadWestvaco is a resin plant in Charleston, SC. They have a drum filling line that operates with an automatic filling arm. When a drum is filled an automatic valve closes which causes an extreme water hammer effect. All the pipes leading into the system shake so hard they have broken loose from the pipe stringers

Pharmaceutical Valve-Induced Water Hammer

Pharmaceutical Valve-Induced Water Hammer

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.
