Pumps sizes are listed by plastic or metal first and then by smallest to largest.

 
Plastic Pump Listing - See below for metal pumps

Note:  

Model numbers starting with the letter T indicate Turbo-Flo® air valve system
Model numbers starting with the letter P indicate Pro-Flo® air valve system
The Wil-Flo™ air valve system is no longer available.  
See air distribution system for details of the air valve systems.

Notes regarding Wilden plastic construction pump. 

Wilden "Champ" was a name given during the introduction of the plastic pumps - it is still true however the term is no longer commonly used.  It indicated that the pump was constructed of thermoplastic and was not specific to the material of construction.  Today, a very descriptive model number system is used that describes every component detail is in place.  When ordering replacement parts please be as detailed as you can - this will help both of us. 

Solid Teflon o-rings for plastic pumps have been replaced by Teflon® encapsulated Viton® o-rings.  This change improves the sealing ability of joints and a softer more forgiving seal.
