Installations with a Suction Lift
Installations with a suction lift over 1 metre require a good quality foot valve to avoid
loss of prime.
Installations with Flooded Suction
Installations with flooded suction require a gate valve so water supply can be turned
off for pump removal and servicing.
WARNING
DO NOT RUN DRY
DO NOT RUN WITH LOSS OF PRIME
DO NOT PUMP WATER CONTAINING ABRASIVE MATERIALS
Abrasive Materials
The pumping of abrasive materials will cause damage to the pump which will then
not be covered by the guarantee.
Water temperature in pump must not exceed 80oC, or damage
caused will not be covered by guarantee.
Connection of Mains Scheme or Town Water
Supply to either Suction or Discharge of Pump
Most Water Supply Authorities have strict regulations regarding direct connection of
pumps to mains water supplies. In most cases an isolating tank is required between
mains supply and pump. Davey also recommend this method. Directly applied
mains pressure can exceed pump operating pressure and damage pump.
Davey Water Products Pty Ltd can not accept responsibility for loss or
damage resulting from incorrect or unauthorised installations.
NOTE - If connecting your XF Pump direct to mains water, the
casing pressure (maximum outlet pressure) must not exceed
800kPa (8bar/116psi).
