The Burks 3204G7-2-AB is a Bronze Centrifugal Pump and Motor with a Bronze 7. 63 inch diameter Impeller, Buna-N/Carbon/Ceramic/Stainless Steel Mechanical Seal, 2-1/2 Inch Inlet x 2 Inch Outlet Ports, close coupled to a 2 Horsepower, 1750 RPM, 230/460 Volts, 3 Phase, ODP Open Drip Proof, 60Hz, 145JM nema frame electric Motor. This pump is an All Bronze version. Bronze pumps are suitable for most common liquids in the pH range from 4-11. This compact Centrifugal pump is designed for general purpose pumping, water circulation, and liquid transfer or booster service. It is silent, and efficient, so it is ideal for convenient equipment location in offices, laboratories, public areas, and living quarters. Long trouble-free service life has made these centrifugal pumps acceptable for industrial uses or wherever clean or contaminated liquids compatible with Bronze is to be transferred or handled. These close-coupled centrifugal pumps from Burks provide economical performance for 50 to 210 GPM applications requiring heads to 230 feet. For exact performance of this pump please consult the performance curve for the horsepower and impeller diameter speicified for this model. By combining the latest concepts in pump design with precision manufacturing, the G7 Series pumps deliver excellent efficiency and low NPSH requirements. Efficient manufacturing processes and highly optimized mechanical designs control costs. Maintenance costs are kept to a minimum by combining a highly serviceable design with quality components to provide a long service life. This Burks centrifugal pump has a single rotating enclosed bronze impeller of the latest hydraulic design for maximum efficiency. The pump impeller is balanced for vibration-free operation and threaded onto a stainless steel motor shaft. The bronze pump casing/volute has a replaceable casing wear ring that prevents wear on casing and is easy to replace. Back pull-out design eliminates the need to disturb piping should the pump ever require service - the casing stays in the line. Centerline discharge. Stud mounted casing assures positive alignment and allows rotation of discharge to eight different positions. Openings are provided for test gauges, for venting and for draining the pump. This pump has a Bronze shaft sleeve - the gasketed and keyed hook-type sleeve protects shaft from wear and corrosion in seal area. The operating temperature limits of this All Bronze pump depend on the seal elastomer and the operating temperature limit for the pump with the Buna-N seal is 225 degrees F (107 degrees C). The pump shaft seal is a mechanical seal with ceramic seat and carbon seal face for maximum durability, and long trouble-free service. While this pump can be run dry for short periods of time, a lack of liquid will damage the Mechanical seal. The motor on this pump has open drip proof construction and is rated with pump motor service factors for continuous duty operation. This motor must be installed with magnetic a starter which must provide full 3-leg protection. Failure to use correct starter and overloads will void motor warranty. Motors are 145JM frame size with NEMA standard mounting flange, extended steel shaft and dual bearings. These motors offer the advantages of quiet operation, controlled shaft deflection for longer seal life, and bearings sized to provide good service life. The wetted material in contact with the liquid are Bronze, 303 Stainless Steel, and Buna-N. The dimensions of this pump are 22 inches long, 13-1/2 inches high, and 16-1/2 inches wide.
WEIGHT : This pump and motor unit weighs 134 Lbs.
Standard self-adjusting Buna-N shaft seal for temperatures to 225 degrees F (107 degrees C) and pressures to 150 psi (1034 kpa).
Casing and motor adapter are Cast Bronze.
Enclosed 7.63 inch bronze impeller of the latest hydraulic design for maximum efficiency, impeller is balanced for vibration-free operation and threaded onto stainless steel motor shaft.
Case wearing ring prevents wear on casing and easily/inexpensively replaced.
Vertical center-line discharge makes pump self-venting, avoids vapor locks and minimizes pipe strain.
Backpull-out design eliminates the need to disturb piping should the pump ever require service - the casing stays in the line.
After careful assembly and inspection, every pump is factory tested and meets Hydraulic Institute standards.
Liquid handling requirements are much more involved than they were five years ago. The variety of liquids being handled has increased along with temperatures and pressures. Todays installations demand quiet, smoothrunning pumps with long life. High efficiencies, robust case construction of Bronze, and impeller construction of Brass makes these pumps an ideal selection for applications that require easytomaintain, reliable, long lasting pumps. Typical applications for the 3204G72AB include Hot Water Circulating Pumps, Cooling Tower Makeup, Boiler Feed Service, Transfer Service, TV and Radar Tube Cooling; condenser, chilled, and hot water systems in HVAC; process secondary pumping, and municipal drinking water. This pump is also the best solution for General Water Service, Chilled and Hot Water Systems, HVAC Industrial Processes, Municipal Drinking Water, Sprinkler and Irrigation Systems. NOTE Thick or viscous liquids are not recommended for centrifugal pumps. Because centrifugal pumps are more efficient at higher shaft speeds, pumping of viscous or thick liquids is difficult. It is possible to lose as much as 40 percent pump performance when attempting to pump liquids of viscosity equal to S. A. E. 30 oil at room temperature. S. A. E. 30 oil at room temperature has a viscosity of 2000 Saybolt Seconds Universal.
