## Abstract

A method can include receiving, at a control module, first pump characteristic data from a data source associated with a pump, sensing second pump characteristic data from a flow system using one or more sensors, comparing the first pump characteristic data to the second pump characteristic data sensed in the flow system, and determining a health of the pump based on the comparison of the first pump characteristic data to the second pump characteristic data.

## Claims

### Claim 1

A non-transitory computer readable medium comprising computer executable instructions to cause a computerized device to perform a method, the method comprising:
receiving, at a control module, first pump characteristic data from a data source associated with a pump;
sensing actual first pump characteristic data from a flow system using one or more sensors;
comparing the first pump characteristic data to second pump characteristic data;
determining a health of the pump based on the comparison of the first pump characteristic data to the second pump characteristic data; and
storing the first pump characteristic data until shut down or reset of the flow system to allow an update of the first pump characteristic data at each start-up;
wherein receiving the first pump characteristic data includes receiving the first pump characteristic data at start-up and/or initialization of the control module, wherein receiving the first pump characteristic data includes receiving the first pump characteristic data only at start-up and/or initialization of the control module.

### Claim 2 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the data source is or includes a digital memory device connected to the control module, wherein receiving the first pump characteristic data includes reading the first pump characteristic data from the digital memory device.

### Claim 3 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the data source is or includes a pump label, wherein receiving the first pump characteristic data includes receiving scan data from a scanning device operatively connected to the control module.

### Claim 4 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the method further comprises outputting a health warning signal if the health of the pump is determined to be less than a predetermined threshold.

### Claim 5 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the method further comprises shutting down the pump and/or removing the pump for maintenance and/or replacement if the health of the pump is determined to be degraded below a predetermined threshold.

### Claim 6

A system, comprising:
a control module for a flow system, the control module configured to perform a control module method, the control module method comprising:
receiving first pump characteristic data from a data source associated with a pump, wherein receiving the first pump characteristic data includes receiving the first pump characteristic data at start-up and/or initialization of the control module;
sensing second pump characteristic data from a flow system using one or more sensors;
comparing the first pump characteristic data to the second pump characteristic data sensed in the flow system;
determining a health of the pump based on the comparison of the first pump characteristic data to the second pump characteristic data; and
storing the first pump characteristic data until shut down or reset of the flow system to allow an update of the first pump characteristic data at each start-up.

### Claim 7 (depends on 6)

The system of claim 6, wherein receiving the first pump characteristic data includes receiving the first pump characteristic data only at start-up and/or initialization of the control module.

### Claim 8 (depends on 6)

The system of claim 6, wherein the data source is or include a digital memory device connected wirelessly or wired to the control module, wherein receiving the first pump characteristic data includes reading the first pump characteristic data from the digital memory device.

### Claim 9 (depends on 6)

The system of claim 6, wherein the data source is or includes a pump label, wherein receiving the first pump characteristic data includes receiving scan data from a scanning device operatively connected to the control module.

### Claim 10 (depends on 6)

The system of claim 6, wherein the control module method includes outputting a health warning signal if the health of the pump is determined to be less than a predetermined threshold.

### Claim 11 (depends on 6)

The system of claim 6, wherein the control module method further comprising shutting down the pump and/or removing the pump for maintenance and/or replacement if the health of the pump is determined to be degraded below a predetermined threshold.

### Claim 12 (depends on 11)

The system of claim 11, further comprising the pump operatively connected to the control module and having the data source mounted to the pump.

### Claim 13

A pump, comprising:
a pump housing containing one or more pump components; and
a data source mounted on or in the pump housing, the data source comprising first pump characteristic data configured to be read from the data source to provide a control module with the first pump characteristic data at start-up and/or initialization of the control module, wherein the control module is configured to store the first pump characteristic data until shut down or reset of the flow system to allow an update of the first pump characteristic data at each start-up.

### Claim 14 (depends on 13)

The pump of claim 13, wherein the first pump characteristic data is pump performance data detailing pump performance when the pump is new.

### Claim 15 (depends on 14)

The pump of claim 14, wherein the data source includes at least one of a 2D barcode or a 3D barcode disposed on or formed on a surface of the pump housing.
