Steep Head/Capacity Curve
Pumping capacity varies only slightly as pressure changes. Steep
pressure characteristic overcomes temporary line resistances.
Self-Adjusting Impeller
M50 • 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 Seals
Bronze 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 Pressure
Rigid stucture is designed for maximum casing strength.
100% Tested
Every pump is fully tested to verify performance prior to shipment.
Volatile Fluid Handling
The 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.
Shaft
Standard shaft is of high strength 416 stainless steel.
Motors
Standard 56C face motors are utilized up to 3 Hp. Five Hp and
above are TEFC on vertical base mount units.
Best Efficiency
New pump designs optimize efficiency for each size.
Non-Cavitating
M50 • L50 Series pumps may be operated under adverse inlet
conditions without audible or measurable cavitation.
