Pressure Washer Pump Repairs
Americlean can re-manufacture your damaged triplex pump manifold.
High pressure triplex pumps should have the high
pressure valve seat o-rings replaced at maintenance intervals.
When the o-rings are not replaced and they fail and a leak begins.
It is only small at first, but as high pressure water escapes around
the failed o-ring it begins to extrude or wear a groove in the
manifold casting. When this happens installing a new o-ring will
not solve the problem. When this happens the manifold has to be
replaced or repaired. This is because water will leak past the
new o-rings through the groove that was extruded into the metal
casting caused by the failure of the old o-ring.
Only by re-machining the manifold until the groove is removed
can the manifold be saved. In some cases such as with CAT PUMPS,
new oversized seats have to be manufactured and installed to match
the amount of material removed from the manifold. When this operation
is performed the seat will seal as it did when it was new.
The cost savings can be quite high.
For example our service department had a customer bring in a Simpson
machine with a Cat 57 triplex pump. The machine was around five
years old and the high pressure valve seat 0-rings had not been
replaced since it was new. They were leaking and a groove had already
been extruded into the casting.
The replacement manifold was $1100.00 almost the cost of a new
pump. The customer was sick since the cost of the o-ring would
have been only a couple of dollars to
replace. This was the first repair we decided to attempt on a damaged
manifold. We sent the manifold to our machine shop for the re-machining
process and to have slightly larger valve seats made.
The total cost for re-machining the manifold and new seats was
$250.00, a savings of $850.00!
Another repair was to a General pump that had to have all of the faces re-machined.
The replacement cost of that manifold was $425.00. The repair was $125.00.
