WZI 900 AUTO - pump with a frequency converter
WZI 900 AUTO is a compact self-priming pump with a built-in frequency converter, designed for collecting and pumping technically clean raw water from household intakes and for increasing the pressure from the water supply network. It maintains constant pressure at all draw-off points, operates quietly and consumes less energy than a classic pressure booster set. With a 900 W motor, it can lift up to 43 m and deliver up to 75 l/min.
For whom
- Owners of single-family houses - constant water pressure throughout the installation and quiet operation allowing installation close to the living area.
- Residents of areas with a weak network - effective raising of too low water pressure.
- Small commercial premises - energy-saving pressure maintenance with variable water demand.
- Gardeners and allotment gardeners – Power supply watering with water from a well or reservoir.
- Installers – simple two-button configuration without separate automation, clear parameters and manufacturer support.
Application
The WZI 900 AUTO pump plays the role of the heart of the home water installation: it draws raw water from your own well or raises too low pressure from the water supply network, maintaining an even flow at each draw-off valve. This is a solution for modernizing the water installation at home wherever a classic hydrophore does not provide stable pressure. The pump is not a water treatment device - if water from your own well is to be used for food purposes, it must be properly treated and quality controlled.
The device will also handle garden irrigation and watering with rainwater collected from the tank, as well as water supply for smaller commercial premises. The WZI 900 AUTO 230 V inverter pump works with typical installations found in Polish single-family houses.
Features of WZI 900 AUTO
WZI 900 AUTO is a pump with a built-in inverter that smoothly regulates the rotational speed of the permanent magnet motor and maintains the set pressure regardless of the number of open intake points. Soft start reduces mechanical loads and wear of the engine and hydraulic parts, and operation at reduced speeds translates into quiet operation and lower energy consumption compared to classic hydrophore sets.
Configuration comes down to setting the working pressure using two buttons + and –; the current parameters are shown on the inverter's LED display. The controller provides a set of protections: protection against dry running (without the need to install probes and sensors in the well), engine overload, too high and too low voltage and water hammer.
The hydraulic part is based on durable materials: the impeller is made of brass, the diffuser is made of cast iron, and the shaft is made of AISI 304 stainless steel. The casing is made of plastic, and the mechanical seal is ceramic/graphite. The IP54 protection level and quiet operation allow it to be installed also in utility rooms.

Frequently asked questions (FAQ) – what is the WZI 900 AUTO pump used for?
What is the WZI 900 AUTO pump used for?
WZI 900 AUTO collects and pumps raw water from its own well and raises too low pressure from the water supply network. Thanks to the built-in inverter, it maintains constant pressure on all intake valves, and the efficiency of up to 75 l/min covers the needs of a single-family house or a smaller commercial premises.
How does a pump with an inverter differ from a classic hydrophore set?
Instead of cyclical switching on and off, the pump smoothly regulates the engine speed, adapting it to the current water consumption. The result is constant pressure, gentle starts, quieter operation and lower power consumption than in a system with a traditional hydrophore.
Is WZI 900 AUTO suitable for watering the garden with rainwater from the tank?
Yes, the pump can draw water from a rainwater tank or well and power the irrigation system. When drawing from an open source, a non-return valve should be installed on the suction pipe to prevent automatic emptying of the pipeline - appropriate elements can be found in accessories for surface and hydrophore pumps.
How do I start and configure the pump?
Start-up does not require a specialist visit - the working pressure is set using two buttons + and -, and the pump then maintains it automatically. The current operating parameters are shown on the inverter's LED display.
Where can you buy the WZI 900 AUTO pump?
Dambat, as a manufacturer, does not conduct direct sales. The WZI 900 AUTO pump is available from our trading partners, installation wholesalers and authorized online distributors.
What warranty is covered by the WZI 900 AUTO pump?
IBO – 24 months (2 years) manufacturer's warranty. Warranty and post-warranty service is provided by Dambat.
