Used DURCO MK3 STD #9353071 for sale

DURCO MK3 STD is a single stage, centerline mounted, end suction centrifugal pump. It is designed for use in a wide variety of general purpose applications, including industrial, commercial, and HVAC systems. It is constructed with a lightweight, corrosion-resistant bronze alloy body and features a baffled, high-efficiency, back pull-out impeller. The pump is powered by a 50 Hz, three-phase electric motor with standard NEMA 56C enclosure. The standard impeller is dynamically balanced with an accuracy of +/- 0.125 inches and has a maximum diameter of 7.07 inches. MK3 STD can move liquids at capacities ranging from twelve-hundred (1200) up to four-and-a-half-thousand (4500) gallons per hour, with a maximum differential pressure of one-hundred-and-fifteen (115) psi. It has a maximum suction head of twenty-nine (29) feet at shutoff and a maximum runout of five (5) feet. The pump has a low operating noise, typically below seventy (70) dB SPL. The bearing and seal design allow the pump to operate with a minimum of vibration over a wide range of operating pressures. DURCO MK3 STD features a dynamically balanced, radial-vane impeller that provides an excellent pumping efficiency of up to 89% at up to fifteen-thousand (15,000) rpm. The impeller is constructed of bronze with non-corrosive bushings and has four vanes that are two-and-three-eights (2 3/8) inches in diameter. The impeller can handle media with a maximum temperature of two-hundred-and-fifty (250) degrees Fahrenheit. The bearing and seal design allows for longer life and better overall system reliability. The pump also includes a lube oil system with a filter and level sensor. The lubricating oil is designed to reduce noise levels and extends the life of mechanical components. The lubricant should be checked and changed regularly for maximum performance. MK3 STD also has an optimized, modular, and simple installation, offering minimal disruption to surrounding systems. It is designed to easily connect with a wide variety of piping systems through its two flange ports. The included installation kits are useful for quickly and easily installing the pump into any system and allow for adjustable feet for perfect alignment.
