Spraying pumps distribute water or liquids to be applied to plants and crops, in agriculture, gardening and small green-maintenance jobs. The backpack pump is carried on the back and is used for limited areas; the petrol motor sprayer works on larger plots, where a constant flow rate and pressure are needed.

The most important factors are the area to treat and the duration of the job. For hedges, small vegetable gardens and fruit trees, an 18-litre backpack pump is enough, such as the S 18-M model. For orchards, vineyards or large plots, a motorised sprayer is better, as it reduces fatigue and keeps the pressure more even. Always check the tank capacity against the planned work.

A membrane hydrosphere, also called a membrane tank, is a pressurised water store placed between the pump and the points of use. It reduces continuous pump starts, keeps the delivery pressure more stable and protects the motor. The pressure switch mounted on the tank controls the start and stop of the pump based on the pressure reached.

The pressure switch is chosen based on the working pressure of the pump and the type of system. In the Wortex catalogue you will find models such as the FSG-2 and the PM 5: compare the operating range and the connection on the technical data sheet. An unsuitable pressure switch can make the pump start too often or fail to start when needed. The pressure gauge helps you check the actual pressure in the system.

A pressure booster set with inverter keeps the pressure constant when a tap is opened or several water outlets are used at the same time. The inverter adjusts the pump speed to the demand, so the pump only works when needed. It is useful in houses, villas and small service-water or irrigation systems, where the flow rate often changes during the day.

Petrol compressors such as the DSB 22/680 and CB 25/520 produce compressed air where there is no mains electricity: construction sites, agricultural work, road maintenance and mobile workshops. They are chosen based on the air flow and pressure required by the tool to be powered. Use them outdoors or in well-ventilated spaces, because the petrol engine produces exhaust gases.

Clean the water filter when it clogs and check that the non-return valves and foot valves have no debris. The mechanical seal is a part subject to wear, especially with dirty or sandy water. Before periods of inactivity or frost, drain the pump and the hose to avoid damage to the internal parts. Also check the electrical connections.
