7. Mechanical installation
7.1 Location
The pump is suitable for indoor and outdoor
installation. It is resistant to sunlight.
7.2 Foundation
Mount the pump on the base plate with hori-
zontal suction port and vertical discharge port.
The pump must be installed horizontally.
The maximum permissible inclination angle is
± 18 °. See fig. 2.
Fig. 2 Horizontal installation of the MQ
To prevent movement and vibrations, the
pump and base plate can be secured to a solid
foundation by means of the bolt holes in the
base plate. For pipework connection, see sec-
tion 7.4 Pipework.
7.3 Space requirement
For inspection and service, allow a minimum
clearance of 60" behind the pump.
Fig. 3 Minimum clearance behind the
pump
Being self-cooling, the pump requires no
space or ventilation at the sides.
7.4 Pipework
The pump is supplied with 1" NPT screwed
connections. Fit the connections in the suction
and discharge ports. See fig. 4. The pump dis-
charge port is flexible, ± 5 °, to facilitate the fit-
ting.

suction and discharge ports
Note
For outdoor installation, the pump
must be fitted with a protective
cover (accessory). See section
7.5 Protective cover and
13. Accessories.
Note
Should the unlikely event of an
internal leakage occur, pumped
liquid will be drained out from the
base and/or end cover instead of
damaging the pump. Install the
pump in such a way that no unde-
sirable collateral damage can
arise.
