Wilden AODD pump helps pigment manufacturer save thousands annually

John Brooks Company's AODD-pump experts solve important issues for many customers.

John Brooks Company Limited carries air-operated double-diaphragm (AODD) pumps by Wilden, which have served customers as efficient, long-term solutions. Recently, a Quebec manufacturer of titanium-dioxide pigments needed a new pump for a refining application through chloride and sulphate processes. Here is how John Brooks Company helped this customer save thousands of dollars per year in air consumption, part replacement, and more with the Wilden solution.

Highly viscous, abrasive liquids

Titanium-dioxide pigments are used in the manufacture of paint, plastics, sunscreen, cosmetics, and certain foods. This metal must be refined into a uniform particle size using AODD pumps, as they can handle highly viscous, abrasive liquids. The customer planned to use a Yamada unit, but an AODD specialist from John Brooks Company made a case for why a Wilden pump would be a superior investment.

The Yamada pump had three weak spots:

• Flow. With a system pressure increase to 30 pounds per square inch, the Wilden option could deliver 210 gallons per minute (GPM), whereas the Yamada one delivered only 150 GPM.
• Energy consumption. The Wilden pump required significantly less pressure than the Yamada one did, translating into more than $3,700 in savings annually.
• Costs for parts. Because the Wilden pump had about ten times fewer components than the Yamada one did, the former would likely require far less part replacement and labour.

The customer installed a Wilden PS1500 Pro-Flo shift bolted plastic AODD pump from John Brooks Company. Among the results were substantial increases in efficiency and reduced costs. Since the Wilden pump required less energy and air consumption to function than the Yamada would have, the customer’s 24/7 operations resulted in a yearly energy savings of $2,500. The higher flow rate with greater efficiency also resulted in ample annual savings; one Wilden pump accommodated the customer’s flow requirements more effectively than two Yamada units could. The Wilden unit had a removable pilot sleeve and air-valve assemblies, with few parts to replace or maintain.

The choice was obvious, and the customer stuck with the Wilden.
