Suction chamber for a horizontal pumping system

A suction chamber for use in a pumping system having a motor, said suction chamber, and a pump, the suction chamber comprising:

• a housing defining a housing interior;
• the housing having a pump end and a motor end, and having a removable end plate at the pump end thereof and an end plate at the motor end thereof;
• a fluid inlet for receiving and communicating a fluid with said housing interior;
• and
• a removable seal assembly disposed in said housing interior for preventing said fluid from leaking through said motor end of said housing, said seal assembly having a central opening for receiving a drive shaft extending from said motor to said pump, wherein said removable end plate may be disconnected from said pump end of said housing and said seal assembly removed in its assembled condition through said pump end of said housing.

A pumping system comprising:

• a motor;
• a drive shaft rotated by said motor;
• a pump driven by said drive shaft;
• and
• a suction chamber connected in said pumping system between said motor and said pump, said suction chamber comprising a housing having a seal assembly disposed therein for preventing fluid passing through said suction chamber from leaking through a motor end of said suction chamber, the seal assembly being removable and replaceable as an assembled unit from said housing through a pump end of said suction chamber.

A pumping system comprising:

• a motor;
• a drive shaft rotated by the motor;
• a pump driven by the drive shaft;
• a suction chamber connected in the pumping system between the motor and the pump, the suction chamber comprising a housing having a seal assembly disposed therein for preventing fluid passing through the suction chamber from leaking through a motor end of the suction chamber, the seal assembly being removable and replaceable as an assembled unit from the housing through a pump end of the suction chamber;
• and
• connecting means for connecting the seal assembly in the interior of the housing, the connecting means being easily accessible through the pump end of the suction chamber.
