Viking Pump has once again demonstrated its mastery in engineering design and manufacturing flexibility by redesigning its heavy-duty alloy pumps, both in steel and stainless steel, in an incredibly innovative way. These new models reduce costs and lead times by significantly decreasing the number of casings and brackets required for production simplification, while also offering more options for porting and shaft sealing. All this has been achieved without compromising on performance, and many great new standard features have been added. Best of all, the 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 will largely replace. The new modular pumps retain a similar model numbering system to the previous generation but end with “C†instead of “A.†You can see the full range of Viking Heavy Duty pumps below (fig. 1), with the new modular pumps highlighted in green.
