4" OLA ring well pump

OLA | OLA INOX
Multi-stage deep well pumps, diameter 98 mm, for ring wells. The pumps feature a motor cooling jacket, so the pumps do not have to be fully submerged and there is no need to use a casing pipe, which is required in the case of classic multistage pumps.

OLA AUTO series pumps are equipped with automatic pump operation control, so there is no need to install additional equipment, such as a pressure switch or external PC or SK control. The principle of operation of the sensor is based on flow measurement. When the pump is connected to the electrical and hydraulic installations, turning on the tap will turn on the pump, while turning it off will switch off the pump within a few seconds. The pump has a built-in check valve that limits the return of water from the installation.
Both OLA 60/60 and OLA AUTO can be installed in combination with a hydrophore tank, but remember that when installing OLA AUTO series pumps, there is no need to install an additional pressure switch.
