These pumps are amazingly affordable and will last for decades. I replaced the old pump because I thought it had lost some power (pressure) but I don't think it has. This replacement was easy to install in my 20 year old Proteo (Starbucks) espresso machine. Given the low cost of the pump and the fact that it is used in almost all household machines, the boiler and controller should make up the majority of the cost of these units.
