Weinman JD Series Horizontal Split Case pumps provide an economical choice for applications requiring high heads, such as boiler feed or booster service. Specially fitted pumps of select alloy are also available for specific applications.
In contrast to most opposed impeller two-stage pumps, Weinman JD Series achieves true axial hydraulic balance for extended life of the thrust bearing. Bending load on the shaft and radial load on the bearings are minimized by positioning the cut-waters of the two volutes 180° apart. This assures balance of radial thrust loads.
Attention to design detail and precision craftsmanship combine to ensure that JD Series pumps cost less to buy, less to operate, and less to maintain. JD Series pumps offer reliable service and low cost operation over a wide range of heads and capacities, including:
  • Discharge sizes from 1.5" (3.8 cm) to 3" (7.6 cm)
  • Heads to 800 ft (244 m)
  • Capacities to 600 gpm (136 m3/h)
  • Operating Pressures to 450 psig (31 bar)
