- No shaft sealing arrangement so no maintenance.
- Pump can run dry,
- Effectively handles slurry / sludge
- The pump suffers no ill effect if the pump discharge valve is partially or fully closed
- The vertical glandless pump in normal hydraulic terms does not differ from any conventional centrifugal pump.
- The pump is designed in such a way that the liquid which normally try to pass through the point, where the impeller drive shaft enters the back plate (stuffing box) is diverted and returned as a controlled flow to the suction tank.
- The need for any seal is eliminated by allowing the leakage liquid to escape through the overflow connection of the overflow chamber.
- The liquid entering suction flow around the impeller casing and leaves through the delivery under pressure.
- Between the annular gap of upper rotor casing and impeller some leakage liquid escapes to the overflow chamber.
- The auxiliary impeller (expeller) prevents the leakage liquid going further up and canalizes it through out – IRT in the chamber.
