Housing your Davey Pressure System
To protect your pressure system from the weather, make
sure the pump house is both water proof, frost free and
has adequate ventilation. The pump should be horizontally
mounted on a firm base allowing for drainage, to avoid
damage to flooring etc., that over time may occur from leaking
pipe joints or pump seals. Do not mount the pump vertically.
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.
Pipe Connections
For best performance use P.V.C. or polythene pipes at least the same diameter as
the pump’s inlet and delivery outlet openings. Larger diameter pipe may be used to
minimise resistance to flow when pumping longer distances.
Power Connection
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.
Use unions at pipe connections to enable easy removal and servicing. Use sufficient
tape to ensure airtight seal and hand tighten only. To prevent strain on pump threads
always support heavy inlet and outlet pipes. If there is a likelihood the water supply may
contain solid particles such as pieces of plant or vegetable
matter, a suction strainer should be installed before the
pump to avoid blocking of the pump. Lay suction pipe at a
constant gradient to avoid air pockets which may reduce
pump efficiency.
Do not use pipe thread sealing compounds on any part of this
pump. ONLY use Teflon sealing tape.
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.
