1. A pump including:
two or more pumping chambers comprising compression stroke elements;
one or more drive mechanisms for driving the compression stroke elements; and
a logic arrangement;
a first pumping chamber of the two or more pumping chambers having a first inlet check valve, a first outlet check valve and a first temperature sensor to measure a first temperature;
a second pumping chamber of the one or more pumping chambers having a second inlet check valve, a second outlet check valve and a second temperature sensor to measure a second temperature;
the logic arrangement being configured to:
identify a leak by applying logic, including:
mutually comparing the first temperature and the second temperature; and
mutually comparing a compression-stroke resistance of the first pumping chamber and a compression-stroke resistance of the second pump chamber; and
respond to the identification of the leak by at least one of:
signaling the leak; or
deactivating the pump.
