Burks Pumps End Suction, Close Coupled Centrifugal Water Pumps

Burks Pumps are versatile, low cost pumps engineered for use on most phases of liquid handling. These end-suction pumps are heavy duty, general purpose centrifugal pumps with heavy wall castings suitable for many commercial and industrial applications such as condenser, chilled, and hot water systems in HVAC, domestic water boosting, water recirculation and process secondary pumping. High efficiencies, robust case construction of cast iron with impeller bronze impellers makes these pumps an ideal selection for applications that require easy-to-maintain, reliable, long lasting pumps. Heads To: 160 feet, Flows To: 460 g.p.m.

Design Avantages

Casing Design Radial Split Casing is close-grain iron of 30,000 psi minimum tensile strength. The back pull-out design eliminates the need to disturb piping when servicing because the casing stays in the line. The stud-mounted casing assures positive alignmentwith eight-position centerline discharge casing on G6-1½ models and larger. Enclosed Bronze Impeller: Impeller is of latest hydraulic design for maximum efficiency. It is balanced for vibration-free operation. Replaceable Casing Wear Ring Easily replaceable casing wear ring prevents wear on casing. Available on Series G close-coupled and GN base-mounted units only. Mechanical Shaft Seal Self-adjusting shaft seal handles temperatures to 180°F and pressures to 200 psi. Ceramic seat and carbon seal faces provide long, trouble-free service. Special seals are availablefor higher temperatures and fluids other than water. Standard on G6-1½ through 4G9-4F close-coupled, and on GNA6-1½, GNB, and GNC base-mounted units is a tapped and plugged opening for optional seal face flushing. Bronze Shaft Sleeve Gasketed and keyed hook-type sleeve protects shaft from wear and corrosion in seal area on selected models. Bronze sleeves are standard on units with JM frame motors. All iron units have stainless steel shaft sleeves. Units with 56J frame motors have one-piece stainless steel shafts. Motors Standard 56J & JM frame motors on close-coupled units offer the advantages of quiet operation and controlled shaft deflection for longer mechanical seal life. Bearings are sized to provide optimal service life. Interchangeability The complete liquid end of most sizes of pumps are interchangeable between motors on close-coupled pumps and Burks power frames of comparably sized pumps. This provides greater inventory flexibility plus the option for handling emergency situations.
