Standard design

The MR Liquid-Ring Pump consists of pump casing, casing cover

and impeller made of acid-resistant, duplex-grade steel; EPDM,

FPM or NBR elastomers; stainless steel cap nuts, legs, leg

brackets, and adapter; and, stainless steel shroud with noise

absorbing interior lining protecting the motor. All models have an

external mechanical single seal.

A proportion of the centrifuged liquid is retained around the

periphery and re-circulates, forming a liquid ring that is used to

maintain the prime.

Working principle

The Alfa Laval MR Pump uses the principles of centrifugal force to

operate. However, instead of directing fluid into a ring- or volute

type casing around the periphery, the MR Liquid-Ring Pumps

transfer the fluid into channels on either side of the impeller, in the

front plate and back plate of the pump.

These side channels increase in volume as the impeller passes

the suction port, creating a vacuum and drawing in the liquid. This

volume is then automatically reduced at the discharge port,

creating pressure and forcing the liquid out, thereby providing the

pumping action.

Introduction

The Alfa Laval MR is a well proven liquid-ring pump specifically

developed for effective pumping of liquids with entrained air. The

construction of the MR makes it perfectly suited for use as a return

pump in CIP systems.

hygienic applications within the dairy, food, beverage and

personal care industries that require gentle product treatment

and reliable operation.

The LKHI pump is available in nine sizes to handle capacities up

to 240 m3/h and provide differential pressures up to 8 bar at 50

Hz.

Working principle

On applications where the pumped media contains a mixture of

air and liquid in the suction line, airscrew rotation causes the

formation of a continuous liquid ring within the canister. Due to the

eccentric position of the canister relative to the airscrew, an air

chamber forms between the liquid ring and the airscrew, which

separates into air pockets between the air-screw vanes.

The continuous rotation of the airscrew forces air pockets through

the canister into the suction stage of the impeller which are then

pumped out via the discharge.

Liquid is returned from the discharge via the recirculation pipe into

the canister to ensure the liquid ring is maintained at all times.

When there is no air present, the canister and recirculation loop

have no function and are fully filled with liquid. The liquid passes

through the canister into the suction stage of the impeller,

allowing the pump to act as a traditional centrifugal pump.

Benefits

• Energy efficient: superior efficiency resulting in reduced energy

consumption and CO2 footprint.

• Hygienic: designed according to the most stringent hygienic

design standards and with verified effective CIP cleanability.

• Maximized uptime and reduced maintenance costs: robust
