Description

Pedrollo 4BLOCK 4″ Monoblock Submersible Borehole Pumps

INSTALLATION & USE

Suitable for pumping clean water from boreholes that contain sand (up to 150 g/m3). Because of their high efficiency and reliability they are suitable for use in domestic applications such as domestic water supply as part of a pressure supply and for irrigation, etc.

Pedrollo 4BLOCK pumps can be installed in wells with a diameter of no less than 4″(100m). The pump is lowered into the well by means of the delivery pipe until it is completely immersed. (min 50cm) and at least one metre from the bottom of the well. Care should be taken to ensure that the pump remains submerged as pump operation may cause the level of the water in the well to fall. The pump can be installed either vertically or horizontally. When installed vertically it is advisable to secure the pump by using a stainless steel or nylon cable connected to the special holes provided on the discharge head.

4BLOCK pumps combine the advantages of a submersible pump with the performance of a centrifugal pump. As submersible pumps, they assure reliable operation even with considerable water depth. As multistage pumps they assure high flows, high heads, stable performance curves.
