Axially Split General Industrial Pumps

The single stage LR and LRV and the two stages LLR family of pumps are part of a broad range of axially split, heavy-duty between bearings pumps. These pumps complement the similarly designed LNN and LNNV. Together these products offer 150 impeller-volute combinations, industry's largest array of efficient hydraulic solutions.

LLR Two Stage Design for High Head Applications

•
Back-to-back mounted, single suction impellers reduce axial thrust, prolonging bearing life
•
First and second stage volutes spaced 180° apart to balance radial loads, thereby reducing deflection and prolonging bearing life
•
Crossover cast-in upper casing half provides the rigidity necessary for high pressure applications
•
Interstage bushing minimizes interstage leaking and maximizes efficiency
•
Back-to-back mounted duplex angular contact thrust bearing
