Fully submersible, multistage pump for pumping industrial and drinking water (ACS rating) with radial or semi-axial impellers in sectional construction for vertical or horizontal installation, with built-in non-return valve. Corrosion-free single-phase or three-phase AC motor for direct starting with water-glycol filling. Hermetically cast with enamel-insulated windings, resin-impregnated and self-lubricating bearings. The motor is cooled by the pumped fluid. Therefore, the unit must always be operated immersed. The limit values for maximum fluid temperature and minimum flow velocity must be adhered to. Vertical installation is possible with or without cooling jacket. In cases of horizontal installation, a cooling jacket must always be provided .

Pump control (4)
HiControl 1
HiControl 1	HiControl 1-EK	4190895
	Electronic control and regulation accessories. The Wilo-HiControl 1 series is used for borehole pumps to enable automatic operation. Wilo-HiControl 1 protects the pump against operation with a low volume flow. The volume flow sensor and pressure sensor enable Wilo-HiControl 1 to automate the pump between two values: the start-up pressure and the switch-off volume flow. If the pressure in the network is lower than the start-up pressure, Wilo-HiControl 1 starts the pump. The pump continues to operate until the volume flow falls below the value of the switch-off volume flow. The small internal tank prevents water hammer and cycling. The Wilo-HiControl 1-EK version with electrical cable and built-in socket shortens the installation time as the pump can be directly connected to the power supply. Wilo-HiControl 1 can be mounted on surface pumps or connected to submersible pumps for domestic water supply. Special features Simple installation Especially compact design makes it suitable for many types of installation locations High operational reliability due to electronic fault signal Protection of the connected pumps due to built-in protection against low water levels Simple operation due to clear operating state display and manometer No additional diaphragm pressure vessel required Perfect corrosion protection, due to rust-free materials Wired ready-to-plug for fastest installation. Inline version with input and output in vertical axis and uniform thread connections, suitable for direct connection to the pump housing or wall surface installation with a wall bracket (accessories). Notice The HiControl 1 may be installed only in vertical position with the output at the top! Scope of delivery HiControl 1 EK incl. 1.5 m connection cable with EK adapter plug Cable ties for quick and safe installation of ready-to-plug pump units
