Viking Pump has revolutionized its heavy-duty alloy pump offerings by redesigning both its steel and stainless steel pumps in innovative ways. These new models reduce costs and lead times by minimizing the number of casings and brackets required for production, streamlining the manufacturing process while offering more porting and sealing options. They also come equipped with numerous advanced standard features. Perhaps the best part is that these new pumps are fully interchangeable with Viking's existing steel 123A, 4123A, 223A, and 4223A series, as well as the stainless steel 127A, 4127A, 227A, and 4227A series, and the 724 and 4724 series which they largely replace. The new modular pumps retain similar model numbering to the previous generation but end with "C" instead of "A." Take a look at the full range of Viking Heavy Duty pumps below (Figure 1), with the new modular pumps highlighted in green.
*Some O-Pro® seal models have reduced speeds compared to packed or mechanical seal models. Maximum O-Pro® speed for H & HL is 760 RPM, N is 280 RPM, and R & RS is 225 RPM.
