Grundfos <strong>TP</strong> Series 400 pumps are single-stage, closecoupled<br />
pumps with in-line suction and discharge ports.<br />
The pumps are equipped with a fan-cooled asynchronous<br />
motor. Motor and pump shafts are connected via<br />
a rigid flange coupling.<br />

<strong>TP</strong> Series 400 pumps are available as single-head (<strong>TP</strong>)<br />
models. All <strong>TP</strong> Series 400 pumps have flange connection<br />
PN 10 or PN 25. The largest pumps have DN 400,<br />
PN 40 discharge flanges and a maximum operating<br />
pressure of 25 bar.<br />
The pumps are equipped with an unbalanced mechanical<br />
shaft seal.<br />
The pumps are of the top-pull-out design, i.e. the power<br />
head (motor, motor stool, pump head and impeller) can<br />
be removed for maintenance or service while the pump<br />
housing remains in the pipework. As radial and axial<br />
forces are absorbed by the fixed bearing in the motor<br />
drive-end, the pump requires no bearing.<br />
<strong>TP</strong> Series 400 pumps are equipped with high-efficiency<br />
motors.<br />
