Multistage vertical pumps

It is a pump with several impellers stacked vertically, with each stage adding pressure. It achieves a high delivery head in very little space.

The SACI V-NOX series is designed primarily for pressure booster sets and firefighting equipment, as well as irrigation systems with many emitters, properties with elevation differences, or supplying several homes. The suction and discharge ports are aligned, making installation in a pipeline easier.

All models in the V-NOX 3 series have a nominal flow rate of around 6 m³/h. The difference is the number of stages, indicated by the last digits: more stages mean greater delivery head.

• For a home or domestic irrigation, around 32 m of head: SACI V-NOX 303M 1.2 HP single-phase vertical multistage stainless steel pump.
• Maximum pressure with single-phase power, around 52 m of head: SACI V-NOX 305M 2 HP single-phase vertical multistage stainless steel pump.
• For large elevation differences or agricultural installations, around 104 m of head: SACI V-NOX 310T 5.5 HP three-phase vertical multistage stainless steel pump.

Each data sheet shows the head the model delivers at 6 m³/h. Compare it with the total head you need: elevation difference, plus operating pressure, plus pipe losses.

No. The 230 V single-phase versions go up to 2 HP (303M, 304M, and 305M). From 3 HP onward, all models are three-phase at 400 V.

Above that power, a single-phase motor would require starting currents that are too high for a domestic installation. If you only have single-phase power and need greater head, contact us before buying.

The vertical design, air-cooled motor, and AISI 304 stainless steel hydraulics reduce vibration and noise.

That’s why the V-NOX is a good choice for booster sets installed inside the home, in garages, or in shared plant rooms. In addition, stainless steel resists corrosion from well water and chlorinated water, and does not transfer rust to the water.

Vertical multistage pumps are not self-priming. They work best under flooded suction, that is, with the water level above the suction inlet.

If the water level is lower, install a foot valve and fill the pump body and suction pipe before starting it for the first time. Never run it dry, as the mechanical seal is cooled by the water itself.

Yes. Tell us the flow rate you need, the total head the pump must overcome, and the available voltage, and we’ll recommend the exact model.
