ABSTRACT:
A fluid pumping system that includes a motor and a pump, wherein an output shaft of the motor is directly coupled to an input shaft of the pump. This coupling between the output shaft of the motor and the input shaft of the pump may be the primary mechanism for coupling the motor to the pump. Such a configuration may be called a “floating pump mount”, because the pump is primarily coupled to the motor via the shaft connection. As a result of this connection, the output shaft of the motor may be naturally “aligned” with the input shaft of the pump. To help prevent the pump from freely rotating with the output shaft of the motor during operation, a rotational stop mechanism may be provided. The rotational stop mechanism may include at least one resilient member for absorbing or substantially absorbing at least some of any relative movement between the pump and the motor.
