10 uF, 220v.

The cap is attached to the pump motor by means of a springy bracket.

This is a "sealed capacitor" with no exposed terminals. It is not
like regular caps with push on terminals. There are no exposed
terminals. I can post a picture tomorrow.

I could not find such units at mcmaster or digikey. Are there such
caps sold anywhere at all?

Stuck centrifugal switch? Sure the pump didn't suck in a stray chip and
jam up?

I am not sure. I did not have time yesterday, may look at it today. The
pump has a inlet filter that looks decently enough made to catch
chips.

Um... then how does it connect? Does it have pigtails instead of spade
lugs?

If so... yes, pigtail caps are readily available.

I don't really know what you mean by "sealed", though. All conventional
electrolytics must have some sort of pressure-relief vent ('cept
tantalums... but they're a different breed.)

Tantalum capacitors are not electrolytics - no electrolyte (and thus no
drying out with age).

I think all tantalum caps are considered electrolytics. Don't think
so, just reverse the polarity and wear safety glasses.

Centainly wet slug tantalums are electrolytics.

Ig... what is the nature of the connections? Is it opposite-ends
(axial), single-end (radial), single pigtail on one end with a bolt on
the other end, one axial pigtail with the case clamp as the other
connection? (wouldn't expect one of the last two on a motor, but you
never know)

And last -- if it is an axial with two leads, why couldn't you make up
your own pigtails for a quick-disconnect type?

There are lots of oil-filled film caps out there in several package
styles.

It is operating in a wet area, that's why.

Ok... you're in your "obtuse" mode today.

For purposes of settling on terms, let's say I believe EACH conductor is
a "pigtail".

How many conductors, Ig?

(hint... although anything more than one could be construed as "multi"
under the strictest definition, the term "multi-conductor" is usually
reserved in cable parlance (and Webster's) for "more than two")

I am pretty sure that the pigtail has two conductors, but I did not

the cabinet?

Iggy, that style is commonly available in the US from ordinary electric
supplies. It's sometimes referred to as a "lighting capacitor". Maybe
that's because they're used more in arc lamp service than in motors.

Graybar carries the GE line of lighting capacitors.

fixtures.

Well, put long wires on the motor end, clean the area with solvent and
glop liberally with RTV to seal the connections against moisture. Then,
mount the commodity cap in a safe location.

HVAC contractor supply outfits have these very cheap, but they may need
you to show business identification before they will sell to you.

I ran into that a while ago, but then I remembered I had an EPA "green
card" so I could buy Freon. That was all they needed to sell me a
really BIG run cap for a central air compressor, for about $7.00. I was
fully prepared to pay $50+ for such an item and was amazed at the low price.
So, that $19 green card paid for itself that day!
