Spear Point Installations
When installing a Dynaprime on a
spear or well point as (A) right, a check
valve immediately above the spear will
greatly assist pump operation (when re-
priming).
The Pump may require “topping-up”
with water at initial priming after the
trapped air in the suction pipe between
pump and water level is pumped out.
Housing your Pump
To protect your pump from the weather, make sure the cover provided is both
water proof, frost free and has adequate ventilation.
The pump should be horizontally mounted on a firm dry base allowing for
drainage, to avoid damage to flooring
Connect lead to power supply designated on pump label, do not use
long extension leads as they cause substantial voltage drop, poor pump
performance and may cause motor overload.
Type of Piping to be used
It is recommended that polythene piping be used for the pump suction and the
delivery lines immediately adjacent to the pump. PVC piping may be used as
an alternative to polythene pipe, however, unions should be used with PVC
pipe so that the pump may be removed without cutting the piping.
Connection to your Water source
As your Davey Dynaprime pump has an inbuilt check valve, no external check
valve or foot valve is required. (On some suction lifts it may be advisable to
fit a foot valve to assist with priming. With a foot valve installed at the bottom
of the suction pipe, it may be beneficial to incorporate a “priming tee” in the
suction pipework adjacent to the pump to aid in initial priming of the suction
line).
Installation of a suction strainer is recommended to prevent large items of
foreign matter entering the pump. The suction strainer should have sufficient
area so as to not restrict the water flow to the pump. Ensure that the strainer
on the end of the suction pipe does not rest in debris or mud at the bottom of
your water source as (B) opposite.
Suction Piping
Suction piping should be laid so there is a constant rise from the water source
to the pump. Any high spots will cause pockets of air to form which may
reduce the efficiency of the system. For best performance use pipe of at least
the same diameter as the pump’s inlet.
Choosing a Site
Choose a site with a firm base and as close to the water source as possible
with correct power supply. Make sure your Dynaprime pump is always
connected to an adequate, reliable source of water.
Connection of Outlet Pipework to Pump
To control the flow of water from the pump it is recommended that a gate valve
be installed on the pump outlet - this is particularly advisable when there is a
possibility of the pump delivering water at a faster rate than may be available at
the source (e.g. spear point, spring, well etc.). Use thread tape at all times and
do not over-tighten fittings. For best performance use pipe of at least the same
diameter as the pump outlet.
Prior to using this pump you must ensure that:
• The pump is installed in a safe and dry environment
• The pump enclosure has adequate drainage in the event of leakage
• Any transport plugs are removed
• The pipe-work is correctly sealed and supported
• The pump is primed correctly
• The power supply is correctly connected
• All steps have been taken for safe operation
Appropriate details for all of these items are contained in the following
Installation and Operating Instructions. Read these in their entirety before
switching on this pump. If you are uncertain as to any of these Installation and
Operating Instructions please contact your Davey dealer or the appropriate
Davey office as listed on the back of this document.
Congratulations on your purchase of a high quality, Australian built Davey
pump. All components have been designed and manufactured to give trouble
free, reliable operation.

Before installing your new pump, please read all instructions carefully as failures caused by
incorrect installation or operation are not covered by the guarantee. Your Dynaprime X201
is designed to handle water containing soft solids to 10mm. It should not be used for any
other purpose without specific referral to Davey. The use of the pump to handle flammable,
corrosive and other materials of a hazardous nature is specifically excluded.
Do not use pipe thread sealing compound on any part of this
pump. ONLY use teflon thread sealing tape.
WARNING: Some insects, such as small ants, find electrical devices
attractive for various reasons. If your pump enclosure is susceptible
to insect infestation you should implement a suitable pest control plan.
Power Connections and Wiring must be
carried out by an authorised electrician.
Note: Suction leaks are the largest cause of poor pump
performance and are difficult to detect. Ensure all connections
are completely sealed using thread tape only.
