MR
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 CIP return pump. Understanding the liquid ring pump working principle is key to appreciating its efficiency.
Specifically designed for pumping liquids that contain air or gas
- Ideal for CIP return applications: well-proven design suited to handle liquids with entrained air
- Easy to operate: excellent suction capability ensures limited impact on performance from changing fluid characteristics.
- Long service life: heavy-duty design used in CIP systems for decades.
The Alfa Laval MR pump is specifically designed for pumping liquids that contain air or gas and is most commonly used for CIP return applications across the food, dairy, beverage and pharmaceutical industries. The MR pump is available in three sizes to handle capacities up to 80 m3 /h and differential pressures up to 5 bar at 50Hz.
How the MR centrifugal pump works?
Understanding how liquid ring pumps work is key to understanding the efficiency of MR pumps. Like the Alfa Laval LKH and SolidC pump ranges, MR liquid ring vacuum pumps operate on centrifugal force. However, in the MR design, fluid is not directed into the peripheral wake or volute casing, but into channels on either side of the impeller, on the front and back plates of the pump.
This volume is then automatically reduced at the discharge port, creating pressure and forcing liquid out, thus providing the pumping action.
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.
The combination of expansion and contraction of volume, centrifugal force and liquid ring construction increases the permissible gas content in the fluid being pumped. This in turn makes this type of pump particularly suitable for fluids with entrained gases.

The MR has a unique construction which makes it perfectly suited to pump liquids with entrained gases. The MR is a well proven Alfa Laval technology that is highly suited to these applications.
The most common application for the MR is CIP return. This application contains is a mix of liquid and gas which needs to be pumped where standard pumps have difficulty.
Made from AISI 316L stainless steel and has a robust, heavy duty design which results in a long life.
Available in 3 models MR185S, 200S and 300. The range can pump up to 80 m3/Hr and pressure of up to 5.3 bar. The MR features an "External" mechanical seal for maximum hygiene and one seal can fit up to 3 models thus reducing spare parts holding.
