Typical Low Level Installation
In certain installations it may be necessary to install a 90° bend on the inlet or
outlet connections of the pump before the flexible hose to accommodate a low
level installation.
Below are some preferred connection options. All connections seal on the pump
body using a fibre or rubber sealing washer. Tap connector fittings should be used
which must be of an appropriate pressure and temperature rating.
It is essential when using any of the fittings shown below, that a correct water
tight seal is obtained between the pump body and selected fitting and also the
flexible hose and selected fitting. If in doubt contact the fitting manufacturer and
confirm compatibility with the connection to be sealed.
Carefully check connections and pipework for leaks whilst pump running and
stationary before leaving the installation unattended.
