| The pump is similar to any centrifugal pump. It is always installed in the vertical position and the design is such that any need for shaft sealing is eliminated by allowing a controlled leakage of the liquid being pumped to return to the suction tank with the help of an overflow pipe in the body of the pump. |

| The ability of glandless pump to run dry without any ill effect has made it a popular choice in process industry for effluent treatment. |
| |
| The most important gains to be reaped from the use of glandless pumps are in the sphere of maintenance and the consequent reduction in down -time. |
| |
| The most widely used method of pump installation is as shown. When the pump is started, it will deliver liquid until the suction pipe is uncovered. Subsequently, the pump can be allowed to run dry until the liquid level is restored to the point where re-priming can take place. |
