iSOLAR PDP4 pump installation notes cont.
•
For best lifespan and reliability, a vertical installation is preferred
•
If installed horizontally, pump side needs to be higher than the motor
•
The motor bleed hole must be in the upright position when installed
Borehole installations
•
Damage to pump or motor caused by abrasive or corrosive water is not
covered by the Warranty.
To prevent damage to the pump by aggressive water, an analysis of the bore
water should be carried out prior to installation to ensure pump suitability.
•
The bore must be clean before installation. A helical pump
must NEVER be used to bail a new bore. Warranty does not
cover failure or wear due to abrasives in the water.
•
Know the total depth of the bore and ensure that the pump
does not rest on the bottom or in sand. Ensure 1.5 metres
clear below the pump to the bottom of the bore.
•
Know the pumping level (drawdown level) of the bore and
ensure that the pump is always submerged.
Minimum water level should always be 150mm above the
pump inlet.
In-tank installations
•
The pump can be installed vertically or horizontally.
•
Fit the non-return valve to the top of the pump.
•
Rigid piping is recommended to prevent the pump twisting.
•
Include a flushing or scour valve on the base of tank to enable
periodic cleaning of the tank bottom to minimise silt build-up.
•
Pump side needs to be higher than the motor – motor bleed hole must be
positioned upwards to avoid airlock.
Pumping from an open body of water – Pond or Stream
•
Vertical installation ensures best lifespan, but it is acceptable to
sling the pump horizontally.
•
Ensure the water is drawn constantly from below the
Water surface and without contamination.
•
A simple, buoyant method of mounting the pump is
to build a pontoon from PCV fittings.
Note: Sand content not to exceed 100g/m3 of water pumped
