Fire-fighting units with electric motors that comply with UNI EN 12845 and UNI 10799 standards. The firefighting units S4, SS6, SS7, SS8 are designed for automatic systems equipped with sprinklers and hydrants. Pumps entirely in stainless steel in versions SS6, SS7, SS8. The main and pilot pumps are supplied with 15 meters of power cable. The switchboards are already mounted on a stand for a faster installation. Submersible pumps 4", 6", 7" or 8". Pumps with radial impellers, pump and motor coupled directly via rigid coupling. 4" pumps with impellers and diffuser in technopolymer. 6", 7", 8" pumps with diffusers, impellers, delivery and suction section supports made entirely of stainless steel (AISI 304 or 316 depending on the model). Integrated non-return valve to reduce pressure drops. Stainless steel filter applied to the suction mouth to prevent the entry of dissolved solid bodies. GAS threaded delivery port. Pre-assembled manifold with flanged connection for each pump. The pressure gauge, the pump running signal pressure switch, the check valve, the butterfly shut-off valve, the galvanized steel delivery manifold with pressure gauges and two pump starting pressure switches, the pressure switch test circuit, the expansion tank (if the pilot pump is present) are pre-assembled.

"4"" multi-impeller borehole pumps for clean water, designed for water boosting, gardening and irrigation, lifting water from boreholes in residential building service, commercial building service and irrigation systems also for agriculture. The S4 pumps must be installed in wells with a diameter of at least 4"", or in tanks or cisterns and it increases the pressure of water that can then be used for example to water medium or large gardens or (in the case of models with a greater flow and head) in irrigation systems in agriculture. Hydraulic part made of AISI 304 stainless steel, technopolymer for parts in contact with water. Technopolymer impellers and diffusers. Built-in non-return valve and suction filter. Single-phase version with manually resettable overload protection and capacitor in the electric control panel to be ordered separately (except for the kit version). Overload protection to be provided by the user for the three-phase version. All the model have the ACS certificate. WRAS and DM174 certificates are pending approval. Also available with 4GG motor (water filled) or 4OL motor (oil filled).
Available as standard:
- Only pump body
- Pump body with oil-filled motor
- Pump body with water-filled motor
- Kit with pump body and motor, power supply cable, cord and control box for single-phase version."

"4"" multi-impeller borehole pumps for clean water, designed for water boosting, gardening and irrigation, lifting water from boreholes in residential building service, commercial building service and irrigation systems also for agriculture.
Hydraulic part built in stainless steel AISI 304, technopolymer is used for the parts in contact with water. Impellers and diffusers in technopolymer. Built-in check valve and suction filter. Single-phase version with manual resetting thermo-amperometric protection and condenser in the electrical control panel to be ordered separately (except for the kit version). The three-phase version must be protected by the user.
Oil filled motor
4OL is a two-pole asynchronous motor in AISI 304L stainless steel for parts in contact with water. The cooling and lubrication of the ball bearings is guaranteed by a special liquid approved for food use. The rewindable stator is inserted in an AISI 304L stainless steel jacket secured by steel pins to the upper motor support. Equipped with a carbon-ceramic mechanical seal.
Motor suitable for use with inverters (30 Hz - 50 Hz). Electrical panel supplied or to be ordered separately depending on the configuration chosen. In the three-phase version the protection is the responsibility of the user.
Available as standard:
- Only pump body
- Pump body with oil-filled motor
- Kit with pump body and motor, power supply cable, cord and control box for single-phase version."
