Steep Head/Capacity CurvePumping capacity varies only slightly as pressure changes. Steep pressure characteristic overcomes temporary line resistances. Self-Adjusting ImpellerM50 • L50 impellers utilize balancing holes to promote hydraulic self centering, which eliminates the need for external adjustment. The free sliding impeller exerts no thrust load on the bearings, thereby extending service life. Self-centering is equally effective whether mounted in the horizontal or vertical position. Mechanical SealsBronze fitted pumps have Buna N elastomers, carbon washer, ceramic seat, and stainless steel metal parts. Optional seats and materials are available. 1000 PSI Case Working PressureRigid stucture is designed for maximum casing strength. 100% TestedEvery pump is fully tested to verify performance prior to shipment. Volatile Fluid HandlingThe turbine impeller handles vapors up to 20% by volume, minimizing the possibility of vapor lock. "O"Ring Gaskets"O"ring gaskets are used throughout the M50 • L50 Series pumps to assure positive sealing. ShaftStandard shaft is of high strength 416 stainless steel. MotorsStandard 56C face motors are utilized up to 3 Hp. Five Hp and above are TEFC on vertical base mount units. Best EfficiencyNew pump designs optimize efficiency for each size. Non-CavitatingM50 • L50 Series pumps may be operated under adverse inlet conditions without audible or measurable cavitation.

Low NPSHNew inlet designs along with L50 Series inducer style pumps provide superior fluid handling ability with low inlet head conditions. Balanced LoadsBy staggering each stage's discharge by 180°, the radial loads on the bearings are effectively balanced, and shaft deflection is thereby negligible. Interstage BushingsClose tolerance self-lubricating carbon bearings between each stage limit interstage leakage. |
