Lowara offer irrigation solutions

09.02.2001

A new feature is that the Lowara SV pump coupled with a Hydrovar variable speed drive can aid the irrigation designer by now accepting 2 simultaneous inputs.

These inputs can either be 0-10 Volts or 4-20 mA and can work in two ways:

1) By determining a new operating pressure

2) Modifying the pressure incrementally as the system changes

It is normal practice that in irrigation systems they are split into zones, these zones can be in many metres apart and therefore need the pump to operate at different pressures to compensate for varying pipework lengths. Another scenario is that dependant upon the plants being propagated, there may be needs of different water capacities and pressures, by utilising this new function then the pump will operate at two different pressures and satisfy the users needs.

Chlorine Gas Systems: New Electric Safety Valve Makes the System Safer

13.12.2024 -

Chlorine gas plays a key role in the disinfection of drinking and industrial water. However, handling the chemical can pose considerable health risks – from irritation of the eyes to fatal pulmonary oedema. To further improve occupational safety during use, Lutz-Jesco has developed the VakuStop – a vacuum regulator for dosing systems that is equipped with an emergency stop function to prevent uncontrolled chlorine gas leaks directly at the chlorine gas tank in the event of an emergency.
