Abstract

A fluid vacuum pump includes a motor assembly including a single motor or multiple motors, where one motor may be configured for operation in a first medium and another motor may be configured for operation in a second medium; an impeller assembly including a single impeller, which may of a fixed or variable configuration, or multiple impellers, where one impeller may be configured for operation in a first medium and another impeller may be configured for operation in a second medium; and a linkage operatively connecting and adjustably transmitting power from the motor assembly to the impeller depending on the type of medium present.

Claims26

Dependent claims

A fluid vacuum pump, comprising:

a single motor assembly further comprising one of:
a single motor;
or
at least a first motor and a second motor;
a single impeller assembly further comprising at least a first impeller and a second impeller;
and
a single linkage operatively connecting said single motor assembly and said single impeller assembly to transmit power from said single motor assembly to said single impeller assembly depending on whether said single impeller assembly is in a first medium or a different second medium;
and
at least one of a controller and a selection device configured to selectively adjust operation of at least one of said single motor assembly, said single impeller assembly, and said single linkage depending on whether said single impeller assembly is in said first medium or said second medium;
wherein said first medium is a liquid;
wherein said entire single impeller assembly is submersible and operable in both the first and second mediums and said fluid vacuum pump is operable to pump both of the first and second mediums, either simultaneously or alternately, while the single impeller assembly is submerged in at least one of the first and second mediums.
