A large multinational manufacture of household products in Brazil approached one of our distributor partners with an
coupling problem. They had an array of roof mounted pumps that were exposed to
all the elements of hot summer sun and torrential rain in the winter months.
These extreme climactic swings were causing the metal hubs of the original
equipment couplings to rust and corrode making the coupling changes very
difficult. To replace the elastomeric elements you would need to move the hubs along
the shaft. This was becoming more and more difficult as time went on.
The
Lovejoy solution was to use a Jaw In-Shear style of coupling. This would allow
the element to be changed without the hubs being moved. The customer was
ecstatic and changed all five over the next two months. Even though the cast
iron hubs of the JIS couplings were still exposed to the elements and would
rust, the element and the stainless steel ring would not rust or corrode. This
allows for easy replacement and limited down time.
The maintenance manager of
the facility has stated that the JIS element change takes less than 30 minutes
where the old system was down for at least 24 hours. The end customer has
written this up their companies best practices and will consider the JIS style
coupling for all the pumps in his facility.
On a closing note, the life he is
getting from the Lovejoy JIS coupling is a minimum of three times what he was
experiencing from the original OEM couplings.
