The VersaFlo TP is Grundfos’s single-stage, in-line circulator with a standard TEFC NEMA C-face motor, for systems that run at a constant flow. It is a top-pull-out design: the motor, motor stool and impeller lift out as one unit without disturbing the piping, so one person can service even the largest size. The model number reads size and head: TP 50-160/2 has 50 mm ports, about 16 m (52 ft) of nominal head, and a 2-pole (3450 RPM) motor; /4 is 4-pole (1725 RPM). This build has the bronze pump housing Grundfos specifies for domestic hot water circulation. The TP has no electronics and no app; for variable-flow systems see the TPE3.
Included: the pump with its TEFC NEMA C-face motor (bronze pump housing), close-coupled and assembled.
Flange set, ordered separately: Grundfos sells the companion flanges as a set of two flanges, two gaskets and eight nuts and bolts per pump size (see Accessories), threaded to the pipe size.
Sized at install: a mounting bracket or base plate wherever the piping cannot carry the pump (product guide p. 8).
Covered for 12 months from the date of purchase under Grundfos’s published warranty terms. Grundfos publishes its terms in its US Terms and Conditions of Sale.

Find your model in its size, then read across: each figure is the total head the pump adds at that flow. A fixed-speed pump runs at the point where this curve meets your system curve.

Flows are the points nearest 20%, 50% and 75% of the longest curve in each size, then that curve’s end. Bold = the last column that model’s curve reaches; — = beyond it. 0 GPM is where the curve starts; every value sits inside the head and flow ranges Grundfos prints for each model on p. 5 of the guide. PSI = feet ÷ 2.31.
