Submersible pump motor housing for improving the serviceability of submersible pumps

A submersible pump motor housing assembly, comprising:

• a two-part housing having
• a first housing part with a motor housing portion and a run and start capacitor housing portion separated by a housing wall with sealable ports formed therein, the motor housing portion configured with a motor housing chamber to receive and contain a motor to be arranged therein with oil to be filled to an oil fill line, the run and start capacitor housing portion configured with a run and start capacitor housing chamber, and
• a second housing part being a removable part configured above the oil fill line to detachably couple to and from the run and start capacitor housing portion;
• and
• a capacitive cup configured to be received and removeably arranged in the run and start capacitor housing chamber when the removable part is detached from the run and start capacitor housing portion, the capacitive cup configured with a capacitive cup chamber formed by a side wall portion and a bottom wall portion to receive and contain at least one run and start capacitor combination to be arranged therein, the bottom wall portion having corresponding ports formed therein configured to pass electrical connections to be coupled to at least one run and start capacitor connector of the at least one run and start capacitor combination to be arranged in the capacitive cup chamber, through the run and start capacitor housing chamber, and through the sealable ports of the housing wall to be connected to at least one motor connector of the motor to be arranged in the motor housing chamber of the motor housing portion.

A submersible pump motor housing assembly comprising:

• a motor;
• a run and start capacitor combination having connections configured to couple to the motor;
• and
• a two-part housing having
• a first housing part with a motor housing portion and a pump motor component housing portion separated by a housing wall with sealable ports formed therein, the motor housing portion configured with a motor housing chamber to receive and contain the motor arranged therein with oil filled to an oil fill line, the pump motor component housing portion configured with a pump motor component housing chamber to receive and contain the run and start capacitor combination arranged therein, the sealable ports configured to pass through the housing wall the electrical connections to couple and connect the run and start capacitor combination to the motor arranged in the motor housing chamber of the motor housing portion;
• and
• a second removable housing part configured to detach from the pump motor component housing portion in order to insert the run and start capacitor combination into the pump motor component housing chamber without draining the oil from the motor housing portion, and to attach to the pump motor component housing portion in order to close the pump motor component housing chamber once the run and start capacitor combination is inserted therein;
• wherein the submersible pump motor housing assembly comprises:
• a capacitive cup configured to receive and contain the run and start capacitor combination;
• the pump motor component housing chamber is configured to receive and contain the capacitive cup when the second removable housing part is detached from the pump motor component housing portion;
• and
• the capacitive cup configured to be detachable and removeable from the pump motor component housing chamber.
