A flexographic printer uses more than 40 pumps, all equipped with high-performance diaphragms to transfer ink and solvents. Typically, the diaphragms are changed as part of preventive maintenance every six months.
During and after the COVID-19 pandemic, the customer thought it would be a good idea to have an alternative supplier of parts. A charitable company offered to provide these parts.
The customer purchased and installed third-party parts on their flexo pumps. The result was disastrous. Instead of the usual six-month run time, they were only getting three to four hours of use.
The maintenance planner was called in to solve the issue, but he had not been informed of the cost-driven change pushed by purchasing.
Assuming the parts were sourced properly, the local Yamada distributor was asked for help. Upon inspection, it was discovered that the third-party parts were counterfeit. The customer had unknowingly purchased substandard parts that were not designed or tested to the same standards as the original parts.

We promptly removed the counterfeit parts and replaced them with genuine parts. After this change, the flexo pumps were able to function properly and operate for the expected six-month run time.
This incident highlights the importance of using genuine parts from reputable suppliers to ensure the proper function and safety of machinery. Counterfeit parts not only compromise the performance of the equipment but also pose a potential safety risk to the operators.

A major aluminum extruder relies on Yamada pumps to assist with various processes in their facility that require the handling and transfer of various non-hazardous and hazardous liquids.
Yamada’s seal-less air operated double diaphragm (AODD) pumps have proven to be a simple and reliable solution for many of their applications.

Upon hearing about their willingness to commit to trying a Yamada pump in their process, I coordinated with engineering at Yamada on coming up with a pump offering that would give them a solution to the issues they were experiencing. Previously, the customer had been using a ½” pump constructed of polypropylene with Santoprene® elastomers. Instead of offering the same material and size pump, we decided to suggest a larger ¾” pump to be run at a slower inlet air pressure supply to lessen the wear from the abrasive fluid. Along with increasing the pump size, we also decided to offer an aluminum pump with stainless steel check balls/seats that would hold up better to the abrasive service that was eating away at the seating surface of the competitor pumps.
In addition, we also supplied the pump with abrasion pads, which are unique to Yamada pumps, providing an extra layer of protection between the inner portion of the diaphragm and center disk. These abrasion pads protect against the commonly seen uniform wear pattern that develops in abrasive service applications and helps extend the life of the diaphragm over time. 

We put the Yamada pump in on trial and it proved to be much more successful and durable, as compared to the competitor pumps the customer was already using. Previously they were getting approximately 3-4 weeks of service out of the competitor brand pumps. The Yamada pump stayed in service, without a failure, for 9 weeks! After successful completion of the trial period, the customer then tried larger versions of the same Yamada pump in similar applications, utilizing Yamada’s 2” and 3” pumps. The larger pumps proved successful as well. The plant has now decided going forward to switch all of their diaphragm pumps over to Yamada pumps.
Given the alternative materials of construction we offered for the trial pump to hold up in the abrasive service, and the support from engineering at Yamada, we were able to provide the customer with a pump that held up longer and proved reliably in a demanding ceramic slip transfer application. Thus, allowing us to earn their business and trust all while standing behind our product via a trial.

With the impending rains and floods, the customer was forced to evacuate their facility.  It would be another two weeks before they could get back to the facility to assess the situation and any possible damage.  Their main concern was getting their vital galvanizing line buck up to speed as quickly as possible.  They were astounded to find that all 9 Yamada pumps had been completely submerged by the flood waters for nearly two full weeks.  The customer wasn’t certain if any of the pumps would perform and may have been damaged after being under muddy water for such a long period of time.
WITH SOME HOPE AND TREPIDATION, COMPRESSED AIR WAS APPLIED TO THE PUMPS AND …. ALL NINE PUMPS STARTED IMMEDIATELY, WITHOUT ANY DELAY!SEE WHAT YAMADA HAS TO OFFER!
As I think back on this story, it reminds me of the “torture test” advertisements used in the old Timex® watch TV ads made popular by newscaster, John Cameron Swayze, who hosted the spots.
A number of these ads subjected the watches to a myriad  of trials. For over 20 years, well into the 1970s, Swayze appeared in the advertising series with one kind of Timex watch or another being subject to various physical challenges to prove their durability, shock resistance, and/or superior waterproofing.  In showing the durability of the watch he stated, “It takes a licking and keeps on ticking.”
Yamada’s slogan states that “The Proof’s in the Pump®”  and in my experience over the years, I have seen Yamada outlast and outperform the competitor’s pumps.  So, if I could add my own little catch phrase, “Yamada pumps take a thumping but keeps on pumping!”
