Pump LR-40 - Pumps for food liquids

The LR-40 pump is designed for use in conditions of shortage or temporary lack of medium. The pump is capable of sucking liquid from a pipeline partially filled with liquid, sucking cleaning agents from a tank or device and removing them completely in the cleaning process under way, which prevents the formation of deposits on the walls of the equipment being cleaned.
Normal operating conditions for the pump are to pump a mixture of air, foam and liquid.

The two versions of the pump - the standard LR and the second LRH with horizontal suction port - make it easier to fit into existing installations.
Both pump versions have the same parameters.

Food, Pharmaceutical and Chemical industries as a draw-off pump in CIP return installations.

LR series pumps have a compact monolithic construction in which a specially designed motor shaft forms the base for the impeller and the stator holds the pump casing. The motor body is bolted to a base fitted with four spherical adjustable feet for levelling and positioning the pump. The pump requires no additional foundation. The installed motor cover protects the motor during cleaning of associated equipment and premises.

The LR pump is a type of circulating centrifugal pump, operating on the principle of a rotating liquid ring.

The design of the annular channels, the construction of the impeller and the location of the pump ports allow the pumped liquid to partially remain in the pump casing chamber and it is this remaining liquid that enables the pumped liquid to be drawn in when there is a shortage of liquid or when the liquid flow is completely interrupted.

The pump principle also allows aerated liquid and foamed liquid to be pumped.

Residues of the pumped medium remain in the casing, making it impossible to use the pump in product applications.

The pump can operate with the need to completely shut off the medium at the pump suction.

Material execution: Acid-resistant steel 1.4301.

Shaft seal: face seal, mechanical in graphite ring/silicon carbide +EPDM configuration.
