The Burks 37GA4-3/4 is a Cast Iron Centrifugal Pump and Motor with a Bronze 4. 25 inch diameter Impeller, Buna-N/Carbon/Ceramic/Stainless Steel Mechanical Seal, 1 Inch Inlet x 3/4 Inch Outlet Ports, close coupled to a 3/4 Horsepower, 3500 RPM, 208-230/460 Volts, 3 Phase, ODP Open Drip Proof, 60/50Hz Motor. This compact Centrifugal pump is designed for general purpose pumping, water circulation, liquid transfer or booster service, and is especially well suited for HVAC condesate return, cooling and boiler feed applications because of it's low NPSH. 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 Cast Iron and Bronze is to be transferred or handled. This Burks centrifugal pump has a single rotating enclosed bronze impeller of the latest hydraulic design for maximum efficiency. Liquid enters at the center and is thrown outward radically by centrifugal force. The impeller is not in contact with other pump parts resulting in quiet, efficient, pumping action. The flow produced is not positive which permits the discharge line to be shut off completely without danger of overloading motors or bursting lines, and consequently a relief valve is not required. The pump impeller is balanced for vibration-free operation and threaded onto a stainless steel motor shaft. The operating temperature limits of this 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 jet pump service factors for continuous duty operation. Motors are 56 frame size with NEMA standard mounting flange, one piece threaded stainless steel shaft and ball/ball bearing construction. The three phase motor on this pump must be installed with a magnetic starter which must provide full 3-leg protection. The wetted material in contact with the liquid are Cast Iron, Bronze, 303 Stainless Steel, and Buna-N. The dimensions of this pump are 15-1/2 inches long, 7 inches high, and 8 inches wide.
WEIGHT : This pump and motor unit weighs 44 Lbs.
Standard self-adjusting Buna-N shaft seal for temperatures to 225 degrees F (107 degrees C) and pressures to 150 psi (1034 kpa).
Enclosed 4.25 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.
Discharge can be located in any of four positions.
Casing is close grain iron of 30,000 psi minimum tensile strength.
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 cast iron, and impeller construction of bronze makes these pumps an ideal selection for applications that require easytomaintain, reliable, long lasting pumps. Typical applications for the 37GA43/4 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.
