Principle Of OperationThe 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 would normally try to pass through the point, where the impeller drive shaft enters the back plate(Stuffing box) is diverted and returns 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 flows 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 channelizes it through outlet in the Overflow chamber.
These pumps are ideally suited for continuous operation and for all scrubbing applications. The pumps is at its best with negative suction.
Salient features * No gland or mechanical seal. hence problems associated with gland packing or mechanical seal eliminated.* Pumps can run dry indefinitely with no damage to the pump and hence offering Zero safe minimum flow.* No bearing housing. Hence issues of Oil maintenance and oil services to the bearing is avoided * Direct assembly with the motor avoids issue of misalignment* Saves valuable floor space* Ideally suited for continuous operation* Suited for clear clean liquids and slurry* Offered in 1440 and 2900 RPM
Limitations* Can operate only wherever negative suction exists.* The suction lifts poses a limitation in the installation.* Can be suitable for only those liquids where external priming is feasible* Not recommended for high temperature application or inflammable organic liquids.
