3.1 Mechanical installation
3.2 Pump location
The pump is designed for tank mounting in vertical
and horizontal position. However, only MTR version
H and MTRE version H are suitable for horizontal
mounting.
The pump is positioned in a hole cut into the tank
and is secured to the tank by four hexagon head
screws through the holes in the mounting flange.
Fig. 2 Vertical and horizontal installation
On horizontally installed MTR, MTRE pumps with
motors from 5.5 kW and up the motors have feet and
must be supported.

For horizontally mounted pumps ensure a
sufficient sealing between pump flange
and tank. A sealing gasket will usually
suffice.
Before changing shaft seals for
horizontally mounted pumps, drain the
tank.
