I wouldn't do that .
The rubber impeller pumps can lose the prime and the rubber impeller will elf destruct in less than a minute.
The trick with the gear type water pumps is to make sure that the ends of the gears and the housing is a very good and flat match.
The gear teeth can be worn down to sharp points but as long as the end parts are a close fit, the pump will work 100% |
