Structure and operation

Self-priming: capable of self-priming up to 8 meters after the first filling of the pump body.
Jet system: uses diffuser and venturi to facilitate suction and flow continuity.
Closed impeller: common solution for water pumping applications in technical systems.

Applications

Nautical sector: power supply for onboard systems and technical services.
Plant engineering: pressurization systems and hydraulic circuits (also in configurations with autoclave).
General use: installations where a single-phase self-priming pump is required.

Performance (indicative from manufacturer data)

Flow rate: up to about 60 l/min (3.6 m³/h)
Head: up to about 36 m H₂O

(Values vary depending on usage conditions and the system's operating point.)

Advantages

Self-priming: simplifies system start-up and management.
Materiali tecnici: combination of bronze, brass, and AISI 316 stainless steel.
Single-phase motor: compatible with standard 230 V installations.
Clear identification: product code useful for spare parts and reorders.

Installation notes

At first start-up or after long periods of inactivity, it is necessary to fill the pump body. Installation of a filter and a non-return valve (check valve) on the suction line is recommended. Verify electrical and hydraulic compatibility with the system before installation. During operation, schedule periodic checks according to the manufacturer's instructions.

Additional information
