Tuthill 0L81-A Mounting Foot for LA Series 56 Frame Pumps
The Tuthill 0L81-A is a genuine mounting foot for Tuthill LA Series pumps on a 56 frame arrangement. A bolt on foot turns a flange mounted pump into a base mounted one, carrying the weight of the pump and the piping load away from the drive so the shaft is not asked to take it. It is a straightforward casting, but it is the part that decides whether the pump sits square and stays that way.
The LA and LE builds differ at the flange, with LA using a two bolt pattern and LE a three bolt pattern, so the foot is not common between them. The matching LE part is 0L81-C. Once the pump is mounted, turn the shaft by hand before power is applied. It should turn freely with a definite resistance, and anything binding at that stage is a mounting problem rather than a pump problem.

Frequently Asked Questions
Q: What is the difference between the LA and LE patterns?
The flange. LA pumps use a two bolt flange and LE pumps use a three bolt flange, so their feet are not interchangeable.
Q: Do I still need to align the pump?
With a close coupled adapter, no. With a foot and a separate motor, yes, and misalignment is the most common cause of early seal failure.
Q: Can I mount the pump on its side?
Check the orientation guidance for your build. Port position affects priming, and the service instructions call for both ports facing upward where possible.
Q: Is this included with the pump?
No. Mounting feet and adapters are listed options and are ordered separately from the pump end.
