19 620RE, 620RE4 and 620R Pump installation
A correctly engineered installation will promote the best possible tube life, so please ensure
that the following guidelines are followed:

Avoid tight pipeline bends, pipe reducers and excessive lengths of smaller bore
tubing than that in the pumphead, particularly in pipelines on the suction side.
 Ensure that connecting pipe work and fittings are suitably rated to handle the
predicted pipeline pressure.

If rigid pipework comes in close proximity to the pumphead, a drop-out section of
pipework will simplify tube replacement. When using element pumpheads, ensure
that a minimum of 1m of flexible interface pipework is connected between the
pumphead and any rigid pipework.

Ensure that the controlled waste blanking plug is in position if the controlled waste
port is not in use. See below.

It is advisable to use controlled waste pipe work if pumping hazardous, aggressive or
abrasive fluids or products which will harden in contact with air.

When connecting waste pipe work to the controlled waste port using the coupling
adaptor supplied, ensure that there is adequate clearance underneath the pumphead.
Waste pipe work should run to a suitable container or drain.

The leak detector installation procedure is included in the leak detector kit.

If unsure of an installation please contact your local Watson-Marlow Technical
Support Office for further assistance.
