Internal gear pumps

1 Internal gear pumps Internal gear pumps gather in two main groups as bracket pumps and non-bracket pumps (Table 12). Besides bracket provides possibility to convert into eight different position (45o interval) for easiness of mounting of inlet and outlet mounts in pumps and also provides opportunity to operate pumps long-life under heavy conditions since bushing of pump shaft is more rigid. Furthermore flow of the pump can be increased and decreased with specified ratio by the virtue of adjusting drum existing on the bracket (Table 13). Letter of (K) which is used to call our internal eccentric gear pumps means that it is bracket-pump. (For instance: 2” CA: Non-bracket pump, 2” CAK
