Chemical Feed
Industry Served: Water Treatment
Problem:
Japan Machinery Company, a manufacturer of water treatment equipment, uses air operated chemical feed pumps to inject various chemicals and additives at very high pressures. The reciprocating action of the pumps produced excessive pulsation and vibration in the discharge pipes of the system, which caused broken pipes, failed gaskets, damaged valves, and pulled pipe supports from their foundations.
Solution:
A Blacoh high pressure SENTRY I model H2620A dome top 370 cubic inch pulsation dampener was installed at the discharge of the pumps. The Blacoh dampener has an Aflas bladder for chemical compatibility. By alternately compressing and expanding the compressed air charge within the dampener as the pump strokes, a shock absorber effect is created. This reduces the surge in the system created by the pumping action.
Result:
Since the SENTRY I pulsation dampener was installed, the surge in the system has been dramatically reduced. Valve, pipe joint, and pipe support failure have been virtually eliminated. Installation of Blacoh high pressure pulsation dampeners is now standard on most new systems.

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.
Solution:
A Blacoh 1" Polypropylene unit with PTFE bellows was recommended to the customer. The customer purchased the unit and installed it. He was very pleased with the quality of the flow conditions out of the pump after the pulsation dampener was installed. The customer has since purchased another unit for a similar application.
Result:
First of all, a happy customer. We solved his problem with the help of a Blacoh pulsation dampener. The customer could not believe the results and will use and recommend Blacoh to his other plants to solve pulsation problems.
