The #100 CIN (Cloth-Inserted Neoprene) pump cup has a fabric inserted base and a flared neoprene
lip. This cup was designed for those in the water industry who prefer a synthetic cup as opposed
to a leather cup. Our #100 CIN pump cup is easily identifable because each cup has "A-1
L" molded into the bottom of the cup.
The #100 pump cup performs best in a new cylinder that is used in a clean well. If the well
is sandy or gritty, these particles will get into the cylinder and cause the walls of the cup
to wear, thus breaking down the seal. Also, a cylinder that has been in previous use may be
pitted on the inside and this will cause a poor seal when using the synthetic cup.
