1. A rotating shaft pump seal gland assembly that operably engages a rotating shaft of a pump to mitigate leakage of process fluid along the shaft, comprising:
a first modular section comprising a first body, the first body comprising a proximal face that operably faces a motor end of a rotating pump shaft onto which it is installed, and a distal face that operably faces a pump end of the pump shaft to define a first orientation, the first body further comprising a first inner wall defining a first bore sized to operably receive the pump shaft, wherein the proximal face comprises a first seal channel disposed at the inner wall, the first seal channel sized and shaped to position a first seal element radially inward of the first modular section and to operably hold the first seal element against the rotating pump shaft; and
a second modular section comprising a second body, the second body comprising a proximal face and distal face, the second body further comprising a second inner wall defining a second bore sized to operably receive the pump shaft, wherein the distal face of the second modular section is operably engaged with the proximal face of the first modular section to couple the first bore with the second bore, and to compress the first seal element to operably provide a seal between the inside of the first bore and the second bore along the rotating shaft, the operably engaged first and second modular sections being reversible to define a second orientation.
