Weinman Single-Stage Split Case pumps are recommended for large capacity municipal, commercial and general industrial liquid handling applications,

Incorporating mechanical simplicity with the latest developments in hydraulic engineering, Weinman L Series horizontally mounted pumps provide higher efficiency, longer pump life and lower cost than comparable pumps.

Extra heavy castings absorb vibration and hydraulic noise thereby assuring smooth and quiet operation. Standard pumps are bronze fitted with iron cases. Optional all iron and ductile versions are available. A variety of models offer:

• Discharge sizes from 2" (5 cm) to 12" (30 cm)
• Heads to 450 ft. (137 m)
• Capacities to 6,000 gpm (1363 m³/h)
• Operating pressures to 450 psig (31 bar)

Weinman L Series pumps feature as standard a "V" trough base design that collects water from condensation and seal packing. A connection for drain to waste is provided.

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)

Weinman's Split Case LVM Series pumps provide the same reliable performance as the L Series. Its vertical design occupies less space than horizontal pumps, making installation easier, especially in small or restricted areas. The improved design also makes it easier to perform routine maintenance. The pumps use three-phase motors from
1 hp (0.75 kW) through 400 hp (300 kW) that deliver heads to 450 ft (137 m) and capacities to 6000 gpm (1363 m³/h)
