The pump did not require surgery and could be inserted using local anesthetic in an emergency room or at a patient's bedside.

A battery powered secondary pump requires the following components in parallel with the above others:

This pump requires steel or flexible concrete placing hoses to be manually attached to the outlet of the machine.

The extra pumps and lines require additional oil, causing maintenance costs to rise accordingly.

Elastomeric pumps do not require any electricity and are not gravity driven.

Transporters can carry out either passive or active transfer of materials while pumps require energy to act.

Each pump required the use of 2 D-cell batteries that loaded underneath the tray, out of sight.

Because the net flow of charge is inward, this pump runs "downhill", effectively, and therefore does not require any energy source except the membrane voltage.

As the pump requires energy to function optimally, high sugar levels enhance Z. bailii preservative resistance.

The pump requires routine maintenance and will fall into disrepair if certain procedures are not followed.
