Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.
The 2095-233-234 is an 12v 3.3gpm @ 45 psi wash down pump, you can purchase any pump with at least the same gpm and psi (and even then you can go up or down depending on what the system is designed for, as an example going up to an 4.0gpm pump at 45 psi or 60psi even) just confirm amps stay the same or that the electrical can handle the increase if there is one. As an exact replacement for that washdown pump here is one that would replace it: http://www.ebay.com/itm/Shurflo-Blaster-trade-II-Washdown-Pump-12v-4238-121-E07-/371268186471
As for the 2088-433-344 it is an 12v 4.0gpm @ 45psi freshwater pump, it is an aqua king fresh water pump 4901-4212 and if it cannot be located then you would want to possibly step up to a 4148 or 4148-153-E75 which bumps up from 45 psi to 55 psi. You could also go to the smart sensor 4901-0211 which is a 50psi.
If trying to locate a pump local to you please keep this in mind, the only things you need to follow are the pump specs which are washdown is 12v 3.3gpm @ 45psi and freshwater is 12v 4.0gpm @45psi, and locate pumps based on that info from shurflow or another manufacture, do not worry about the part numbers of your current pumps the only thing that matters is the specs and what they are used for.
