Dear Client
Congratulations on your purchase of a quality pump from the Davies range of
pumping products.
Like all Davies products, quality and reliability are irst and foremost, carefully
chosen from manufactures worldwide to carry this proven brand name and deliver
years of service.
Please carefully read the owners guide and follow the recommendations to ensure
your pump is installed correctly to give you a long and trouble-free service life.
DAVIES UV SERIES
Delivery and Storage
Davies Ultravort UV series pumps are supplied in factory packaging. Please carefully
check the pump for damage after shipping to ensure there has been no damage in
transit – notify your supplier as soon as possible if you are unsure.
Carefully check the pump model is correct as per your order details and of suitable size
and type for your installation. Do not use power or loat leads for lifting or moving the
pump.

Pump Installation
Ensure mains power is disconnected at supply before doing any installation or
maintenance. All installations must comply with any applicable local or national codes.
Not suitable for pumping liquids that are hazardous, lammable, explosive or over 40
degrees.
The UV series pumps are designed to pump dirty water with suspended solids not larger
than maximum free passage size of the pump – see pump speciications list. Check sump
and remove any solids larger than the maximum free passage size prior to installation or they
can cause blockages and damage the pump.
Maximum number of pump starts per hour is 30. Design installation and select pump model
to keep the number of starts to a minimum. If the pump is going to run for long periods,
ensure the motor is submerged above the top cap at all times for adequate cooling.
Ensure system design prevents and protects pump from dry running, dead heading
(maximum pressure) or operating below minimum pressure as these conditions may damage
the pump.
A lifting rope must be tied securely to the pump handle for installation and lifting for
servicing. Do not lift or lower the pump with the electrical cables or loat switch as this will
damage them.
Pump must be installed in a vertical position on a hard level surface.
Pipe work must not be smaller than the pump discharge and with minimum number of
bends or the performance will be aected and there will be an increased risk of blockages.
A ball type non-return valve to prevent backlow and isolator valve with union for servicing
must be installed in the discharge pipework.
If the pump is controlled with the integral loat switch, ensure this is free of any obstruction
that may cause it to get caught and not switch o as run dry will damage the pump and
void warranty. Separate run dry protection and control must be provided for pumps without
integral loat switch.
The pump and pipework must be drained if there is a risk of freezing to prevent damage.
Electrical Installation
All electrical connections must be done by qualiied personal in accordance with all
national electrical codes. Ensure mains power is disconnected from pump before doing
any servicing or maintenance.
Do not use power or loat leads for lifting or moving the pump.
Never operate the pump with wet hands or while in contact with water.

Before connecting the pump to the mains power supply, check the Voltage, Amps and
frequency corresponds with the motor nameplate rating. Single phase pumps under 10Amps
can be connected directly to an electrical outlet, all other models must be connected to a
switch or suitable control box such as Simplex. Pump must be earthed to a suitable ground
connection in accordance with all national codes prior to any other connections.
Ensure all cables and leads are protected from damage, if possible tapped to pipework or
inside conduit to prevent snagging. Protect all connections and plugs from water.
Single phase pumps have auto re-set internal thermal overload protection and a capacitor.
Caution: The pump will stop from overload tripping but will automatically restart once the
motor has cooled suiciently for overload to reset.
Three Phase pumps must be installed with overload protection supplied by the user and set
around 510% above full load Amp rating.
Lightening, surge and overcurrent protection must be provided by the user. Running pumps
o extension cords is not recommended.
Impeller rotation must be clockwise when viewed from the top on three phase pumps. This
can reversed by swapping any two of the supply wires. Running backwards can damage the
pump and void warranty.
Single phase power supply is 230v +-10%, 50Hz.
Three phase power supply is 415v +-10%, 50Hz.
Maintenance
Maintenance must only be done by qualiied and authorised people. Ensure mains power
is disconnected from pump before doing any servicing or maintenance. Pump may be hot
after use, allow to cool down before handling.
The UV series pumps require regular visual inspection to check for any leaks in the system,
control obstructions, vibrations or noises. If anything is detected this must be recorded and
remedied as soon as possible.
The motors and bearings are sealed and no lubrication is required.
The shaft lip seal and mechanical seal oil bath should be inspected for wear annually in light
duty or quarterly in heavy duty applications. For replacement parts please contact your
supplier. Failure to monitor and maintain seal condition or damage to motor caused by seal
failure may not be covered by the warranty.
Single phase motors have a run capacitor which may cause overload tripping or unusual
noises if this is falling, replace as required.
If pump or pipework is getting jammed or blocked regularly, the sump may require cleaning
or change system to reduce the amount and size of solids entering.
