INTRODUCTION: The 150 Series is proven in the following industry fields: Chemicals, Petrochemicals, Refinery, Pulp and Paper, and General Industry



STANDARD: · Steep head capacity curves for applications that require minimum flow change.; · Ability, to handle vapors Lip to 20% by volume.; · Steady flow--eliminates pulsation problems associated with other pump designs.; · Back pull-out design for low cost, one craft maintenance.; · Top vertical centerline discharge.; · Pump has known shut-off pressure as opposed to position displacement- designs.; · Reduced down-time for bearing and seal maintenance.; · Pump built to ANSI B73.1 dimensional standards- for maximum interchangeability.; · Lower operating costs than standard centrifugal pumps at low, flow conditions.; · Balanced double suction impeller design reduces axial thrust.



OPTIONAL: · Jacketed stuffing box for cooling or heating mechanical seal cavity.; · Jacketed bearing frame provides bearing cooling for high temperature services.; · Case centerline mounting for high temperature services (not available on Model 151).



Hydraulic Coverage: "APCO-CHEM" Turbine Pumps Specific speed (Ns) can be thought of as a hydraulic index number indicating a specific type of pump best suited for a particular application. The Hydraulic Institute lists a range of Ns from 500 through 20,000 for centrifugal pumps starting at a straight radial impeller and progressing through an axial-flow design.But, what about Ns's before 500? This is where the unique Apco-Chem regenerative turbine can best serve those special pumping applications. Consider the following pumping requirement at 3500 RPM.: Head (Ft) 600 600 600 600, Flow (GPM) 10 30 60 90, Ns 91 158 224 274. Now try to find a good centrifugal pump that would meet those pumping requirements at a reasonable efficiency, NPSH requirement, and operating life. Rather difficult! However, look at the quality performance a regenerative turbine can give to those requirements. Specific speed, then, is an index that indicates the type of pump best suited for the myriad pumping applications in the marketplace. Ns below 500 can best be handled by regenerative turbines that have the inherent hydraulic capabilities of pumping low flows and high head requirements.
