The arrow on the pump<br />
housing indicates<br />
the direction of flow.<br />
The shaft must always be<br />
horizontal, never vertical.<br />
4.5 Return valve<br />
If a return valve has been fitted, the pump must be set up<br />
(see 5.4.2) so that the minimum delivery pressure of the pump<br />
can exceed the closing pressure of the valve at any time.<br />
Install the sluice gate before and after the pump.<br />
This prevents the fluid from being drained and refilled<br />
when the pump is exchanged.<br />
4.6 Minimum pressure<br />
The minimum pressure in the pump connection at –10 °C…+75 °C<br />
to ensure lubrication of the friction bearings:<br />
at < 75 °C 0,10 bar<br />
< 90 °C 0,55 bar<br />
