DF6-2-1/2 Centrifugal Pumps

DF6-2-1/2 Close Coupled Centrifugal Pump

General Information
  • Four Position Casing. Centerline discharge can be located in any of four positions. Back pull-out design eliminates the need to disturb piping. Should the pump ever require service, as a result the casing stays in the line.
  • Enclosed Impeller. Of the latest hydraulic design for maximum efficiency, impeller is balanced for vibration-free operation. It is precision fit to shaft with key drive and cap screw lock.
  • Mechanical Shaft Seal. Standard self-adjusting shaft seal due to temperatures to 225 °F (107°C) and pressures to 150 psi (1034 kpa). This product has Ceramic seat and carbon seal face consequently for long trouble free service. Special seals are also available for higher temperatures and fluids other than water.
  • Shaft Sleeve. Gasketed and keyed hook-type sleeve protects shaft therefore, no wear and corrosion in seal area.
  • All Pumps Factory Tested. After careful assembly and inspection, EVERY pump is factory tested and hence will meet Hydraulic Institute standards.
  • Protection From Overload. Burks single phase ODP and Totally Enclosed motors therefore have built-in overload protection. All three phase motors and all explosion proof motors must be installed with a magnetic starter which provides full 3-leg protection. Failure to use correct starter while in use and overloads will void motor warranty.
  • Individual performance curves should be checked for final selection.
  • Furthermore See Specification doc and or pdf for Materials of Construction and Maximum Operating Temperatures.
Motor Information

JM Type motors have NEMA standard mounting flange, in addition to 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. All motors are supplied by manufacturers with national field service facilities.

60 Hz – 1750 RPM – ODP (Open Drip Proof)

  • Single Phase: 115/230 Volt.
  • Three Phase: 208-230/460 Volt.

50 Hz – 1450 RPM – ODP (Open Drip Proof)

  • Single Phase: 115/230 Volt.
  • Three Phase: 208-230/460 Volt.

In conclusion, Voltages may differ from some suppliers. Consult factory.
