Paint Manufacturing Abrasive Slurry Diaphragm Failure

Paint Manufacturing Abrasive Slurry Diaphragm Failure

Problem: A major U.S. paint manufacturer uses 3” air operated double diaphragm pumps (AODD) in their tank farm to transfer ingredients to their paint blending process area. One of the main ingredients is titanium dioxide (TiO2) which is both high in specific gravity and very abrasive. The 3” AODD pumps sit at the bottom of holding tanks that are 25 feet tall. Pump inlet pressure is high and this combined with the characteristics of the TiO2 acts to shorten normal pump diaphragm life. When an unexpected diaphragm failure occurs, several thousand gallons of TiO2 can be lost because when a pump diaphragm fails, the TiO2 is pulled through the diaphragm on the pump’s suction stroke and then expelled out the air exhaust.

Decontamination Facility Spray Pulsation

Decontamination Facility Spray Pulsation

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.

Poultry Processing Diaphragm Pump Vibration

Poultry Processing Diaphragm Pump Vibration

Problem: Steggles Chickens of Newcastle uses a 4" electric diaphragm pump to transfer chicken waste from a wash-down sump to a centrifuge. The diaphragm pump is suited to the application because of its ability to handle large solids such as chicken heads and viscous sludge consisting of congealed chicken blood. The pump's reciprocating action created vibration in the piping system which caused damage to brackets, fittings and valves.

Pharmaceutical Pump-Induced Pipe Vibration

Pharmaceutical Pump-Induced Pipe Vibration

Problem: The Boulder, CO Roche Pharmaceutical manufacturing facility uses a 3" air operated double diaphragm pump to transfer methylene chloride from an underground tank to various spots throughout the plant site. The diaphragm pump is ideal for this application because it creates enough vacuum to lift the methylene chloride 12' at an elevation of 5300' above sea level, even when outside temperatures reach 90-100°F. The reciprocating action of the pump causes the discharge pipe and other components in the system to vibrate and shift.

Aerospace Pump-Induced Pulsation

Aerospace Pump-Induced Pulsation

Problem: A nationally recognized leader in the manufacture of solid rocket propellant uses air operated double diaphragm (AODD) pumps to transfer a particularly aggressive fluid to a unique piece of equipment that requires a constant and steady flow. The reciprocating action of the pump causes excessive pulsation in the discharge piping. Constant pulsation causes erratic flow which prevents the pumps from performing as required.

Wastewater Sludge Transfer Pump Pulsation

Wastewater Sludge Transfer Pump Pulsation

Problem: The Maquoketa, Iowa sewage treatment facility uses a twin disc type reciprocating pump to transfer pretreated sewage sludge from a clarifier to a digester. The twin disc pump is ideal for this application because this type of pump has no valves that can clog or restrict flow. Each disc of the pump transfers about one gallon of liquid with each stroke. The reciprocating action of the pump causes the discharge pipe and other components in the system to vibrate. This constant shaking causes joint leakage and premature failure of instrumentation. Pipe support brackets have been pulled loose from the wall.
