TPE2/3 series: TPE 2 or 3 (E) XX-XXX S or N - A or AI or X - F - A or I - XXXX - YYY Where: TPE2 = pump type with normal Asynchronous motor. TPE3 = pump type with E-motor (motor with integrated frequency driver). XX = nominal DN size of inlet/outlet ports (cast iron 32 - 100, S/Steel 32 - 65). XXX = maximum head (dm). S or N = S: Built-in differential-pressure and temperature sensor (TPE3 models), N: Without built-in sensor (TPE2 models). A or AI or X = A: Basic version, AI: PN6 flange, X: Special Version. F = DIN Flanged. A or I = A: Basic Version. Cast iron pump housing and motor stool, I: S/Steel pump housing and motor stool. XXXX = shaft seal type - BQQE or BQBE. YYY = coding for motor. E.g. TPE3 100-120 S-X-F-A-BQQE-GAB

TP series 300: TP(E) XX-XXX/X [Blank] or S or NC - X or BX - F - A or B or S or O or Y or Q - XXXX * Where: TP = pump type with normal Asynchronous motor. TPE = pump type with E-motor (motor with integrated frequency driver). XX = nominal diameter of inlet and outlet ports, DN (32-350). XXX = maximum head [dm] (60-1050). /X = pole number (2, 4, 6). [Blank] or S or NC = Sensor options: [Blank] = without sensor, S = TPE with factory-fitted differential-pressure sensor, NC = TPE with Siemens/Nidec motor with integrated CUE (Grundfos brand of VSD). X or BX = B: Oversize motor, X: Special version. F = DIN flange. A or B or S or O or Y or Q = A: Basic version - Cast iron pump housing and impeller, B: Cast iron pump housing with bronze impeller, S: Cast iron pump housing with stainless steel impeller, O: Ductile cast iron pump housing with cast iron impeller, Y: Ductile cast iron pump housing with bronze impeller, Q = Ductile cast iron pump housing with stainless steel impeller. XXXX = shaft seal: BQQE or BBQE. * = Motor information, does not have any bearing on water contact parts.
