ABSTRACT:
Submersibly installable and operable high volume and low pressure stirrer type liquid transferring equipment comprises a rotor type stirrer driven via a drive shaft passing without making contact along a sleeve rooting centrally in a housing having a downwardly facing inlet and a tangentially arranged outlet. As the casing of the housing is independent of the remainder of the equipment it is fitted with elevating leg plates. Its operative location is accommodated by a location of equipment installation. The stirrer is bolted to a drive assembly via its shaft. The length of the sleeve is established in conjunction with the circumstances of use of the equipment to maintain the zone encompassed by the housing sealed from above by a liquid seal.
