Stainless Steel Multistage Electronic Water Pressure Booster Set with Presflo Vario 900W – 1.25Hp 5C

A fully automatic booster system with a multistage pump and electronic pump control device. Suitable for water supply to homes not connected to the municipal network or where municipal pressure is insufficient. Also ideal for irrigation, garden watering, small industrial installations, and any application where water pressure needs to be increased.

The water controller is an electronic device installed directly on the pump (single-phase or three-phase) in any position, vertically or horizontally, depending on the flow direction. It automates the pump’s activation when there is a drop in pressure (e.g., tap opens) and stops it when the flow ceases (e.g., tap closes), at the pump’s maximum pressure point. These controllers can manage pumps from 0.5Hp to 2Hp.

The pump operation is controlled by the Presflo Vario controller. The pump starts when the pressure drops below the lower limit and stops when it rises above the upper limit. The motor features copper winding, compact and practical construction.

Multistage Pumps:
Multistage pumps offer high flow and head with low energy consumption. They are reliable, quiet, and practical. The maximum suction height is typically around 8 meters. Ideal for pressure boosting and garden irrigation.

The 5CRm 100 multistage water pump with 5 stainless steel impellers and 1.25Hp single-phase motor has a stainless steel body. It is suitable for pumping clean water or similar non-aggressive fluids. Recommended for drawing water from wells, garden spraying, pressure boosting, domestic water supply, and irrigation systems. Only suitable for clean water without solids or corrosive elements.

Installation should be done in well-ventilated areas protected from harsh weather.

Constructed from high-quality materials: stainless steel pump body, five stainless steel impellers, and stainless steel AISI 304 shaft.

Dry Run Protection:
The system shuts off the pump immediately when it detects that the water source (e.g., tank or well) is empty, preventing damage.

Presflo Vario Controller Benefits:

• Automates pump start/stop for single-phase electric pumps up to 2HP.

• Replaces the traditional automation system (pressure switch + expansion tank).

• Sealed electronic circuit protects from moisture.

• Automatic reset after dry running with the push of a button.

• Overpressure protection capable of stopping the pump at a preset level.

Advantage of the New Motor:

• Pedrollo and its engineers are constantly working to improve motor efficiency by using the same or even less energy.

• The 5CRm 100 model has been upgraded — its new motor is now manufactured at 1.25Hp, while maintaining the same pump performance in terms of maximum head and flow rate (previously with a 1.5Hp motor).

• Through this optimization, Pedrollo aims to reduce energy consumption as well as environmental emissions.

Enjoy the performance and quality of your new and improved Pedrollo pump.

It is recommended to use an expansion tank in combination with the electronic controller for the following reasons:

• To prevent frequent starts of the pump

• To stabilize flow and avoid pressure fluctuations in the system

• To protect the hydraulic components of the pump and the installation from water hammer

• To prevent air entrapment in the system

• To reduce electricity consumption
