Description

Pedrollo 4SR2 Borehole Pump c/w Franklin Motor & QEM Control Box INSTALLATION & USE Pedrollo 4SR2 Borehole Pump c/w Franklin Motor & QEM Control Box Pedrollo 4SR2 borehole pumps are suitable for pumping  clean water with a sand content of no more than 150 g/m³. 4SR2 multi-stage borehole pumps are efficient and reliable and as a result are suitable for use in  domestic, civil and industrial applications in particular for the distribution of water in combination with pressure sets, for washing plants, irrigation and pressure boosting fire sets etc. Prices include PUMP and FRANKLIN motor The 4SR series pumps should be installed in boreholes of at least 4” (100 mm) in diameter. The pump should be lowered into the borehole, by means of the delivery pipe, to such a depth (min. 50 cm and at least one metres from the bottom) that it is completely immersed during operation when the level of water in the borehole may reduce. It is good practice to secure the pump by attaching a stainless steel cable to the anchorage points present on the delivery body.
