NEW JET SELF-PRIMING PUMPS 0.75HP 1HP 1.5HP 2HP

OPERATING CONDITIONS: These pumps have been designed to pump neutral clean liquids in which no abrasive solids are suspended at temperatures of no more than 80oC (60oC for electric pumps with plastic impellers or diffusers). INSTALLATION: The pumps must be installed in a dry well-ventilated place with an ambient temperature of no more than 40oC (fig.A). Fix the pump in place on a solid flat surface using suitable bolts to avoid vibration. The pump must be installed in a horizontal position to ensure: that the bearings operate correctly. The diameter of the intake pipe must not be smaller than that of the intake mouth. If the intake height exceeds 4 meters, use a pipe with a larger diameter. The diameter of the delivery pipe must be chosen to suit the flow rate and pressure required at the takeoff points. The intake pipe must be slightly angled up towards the intake mouth to avoid the formation of air locks (Fig. B). Make sure that the intake pipe is completely airtight and immersed in the water By at least half a meter to avoid the formation of vortexes. Always fit a valve at the end of the intake pipe. It is advisable to fit a non-return valve between the delivery mouth and flow rate adjustment gate valve to avoid dangerous water hammering in the event of the pump suddenly stopping. This measure is compulsory if the delivery water column is over 20 metres. The pipes must always be fitted using the related brackets(Fig.C) to avoid transmitting stress to the pump body. Take care not to damage any part by overtightening the pipes when fitting them.
