Which pumps does this discharge valve spring fit?

It fits the Myers C25, C35, C35-20, C35-20-DV, C40 and C40-20 models.

How is this different from the suction valve spring?

This is the discharge spring with 5 coils (Myers 06127A003). The matching suction valve spring for the same C25/C35/C40 series has 6 coils, so the coil count and function differ.

Is this an original Myers part?

No. It is an aftermarket replacement that interchanges with Myers part number 06127A003; the brand and number are listed for identification only and do not indicate original-equipment manufacture.
