Efficient rainwater pumps at a glance
Rainwater pumps enable efficient and sustainable water utilisation in the home and garden. The pumps from WISY reliably pump collected water from a cistern or rain barrel to points of use and help to reduce the consumption of mains water. Choosing the right rainwater pump depends on factors such as delivery head, water volume and location. Whether you need a pump for rainwater utilisation in the garden or a pump for rainwater utilisation in the house, WISY offers the right solution for every need.
Rainwater utilisation thanks to reliable pumps
Rainwater pumps take on the task of extracting water from a cistern and transporting it with the appropriate pressure to various points in the house or garden.
Centrifugal pumps: technology and how they work
Centrifugal pumps work by rotating an impeller that spins water from the centre outwards, thereby building up pressure. WISY uses single or multi-stage centrifugal pumps: With multi-stage pumps, the water is pumped in several stages through a series of impellers connected in series. This design gradually increases the pressure with each stage, allowing water to be pumped over greater distances and heights. Centrifugal pumps consist of two main parts - an electric part and a hydraulic part. The electric part consists of an electric motor, while the hydraulic part pumps the water with the help of fixed guide vanes and rotating impellers. Centrifugal pumps are ideal for rainwater utilisation in the home and garden.
Suction or submersible pressure pump
WISY offers two main types of centrifugal pumps: suction pumps and submersible pressure pumps, which are installed differently depending on requirements:
Suction pumps such as the AspriPlus are installed outside the cistern and draw in water via a pipe. These suction pumps are ideal for installation in the house, e.g. with a suitable wall bracket in the basement. The suction pipe must always remain filled in order to be able to draw in water. A non-return valve is used here to prevent water from flowing out of the pipe back into the cistern when the pump is switched off. This means that a water column is always maintained in the suction hose.
Submersible pressure pumps such as the Multigo and Provedo are centrifugal pumps that are installed directly in the cistern. The multistage Multigo pump reliably pumps the water over long distances and delivery heads thanks to the successive stages. The Provedo single-stage submersible pump pumps large quantities of water while only building up a small amount of pressure. It is particularly suitable for moving a lot of water horizontally. Both pumps are particularly quiet as they operate under water and are therefore acoustically shielded from the surrounding area. They are ideal for building services applications.
Garden pumps with integrated control
The Beta garden pump is a multi-stage submersible pressure pump that has been specially developed for watering gardens. This rainwater pump switches on automatically via an intelligent control system as soon as the water requirement in the system is recognised, for example when a garden hose is opened. Integrated dry-running protection protects the pump against damage if there is no water in the cistern. The Beta pump is therefore ideal for gardening and landscaping. It is often combined with a floating suction filter for water pumps, which protects the pump from sucking in sediment and draws in the water at the cleanest point in the cistern.
Cistern pump: Suction and pressure pumps
WISY offers cistern pumps and sets for pumping water for every requirement, designed both for the garden and for rainwater utilisation in the home:
- AspriPlus - suction pump: As a self-priming, multi-stage centrifugal pump, the AspriPlus is ideal for applications where the pump is installed indoors. The AspriPlus operates quietly and reliably over the long term. Thanks to the additional vibration damping on rubber buffers, it is barely audible even when installed indoors. The AspriPlus pump is available in various pressure stages (3, 4 or 5-stage), depending on the required delivery head and pressure. In combination with the ZETA 02 automatic switch, which enables demand-based control and operates with just 0.2 watts in standby mode, the AspriPlus is particularly energy-efficient.
- Multigo - submersible pressure pump: The Multigo is a multistage centrifugal pump for submersible use. It pumps water directly from the cistern and is designed for continuous operation. With a maximum immersion depth of up to 18 metres and a robust design, the Multigo is ideal for pumping water at consumption points in the home, e.g. for supplying toilets and washing machines. This water pump for the cistern works reliably and can also be combined with a cistern pump set, e.g. with the floating suction filter, to protect the pump from being sucked in by sediment.
- Provedo - submersible feed pump: The Provedo is a single-stage feed pump that is specially designed for large volumes of water with a small head difference. It can pump up to 150 litres of water per minute and is ideal as a feeder pump in large rainwater storage tanks and for applications with high water requirements. The Provedo is made of corrosion-resistant stainless steel and is equipped with a float switch. This switches the pump off when there is a lack of water to protect it from running dry. This protects the pump and extends its service life. This pump for rainwater cisterns is particularly robust and durable and is ideal for large systems.
- Beta garden pump: The Beta pump is specially designed for easy installation in the garden. Thanks to the integrated control system, it reacts automatically to water demand, which simplifies garden irrigation. Its high flow rate and low energy consumption make the Beta pump an ideal choice for garden owners.
Strengths and areas of application
WISY pumps offer high energy efficiency and reliability. Each pump is designed for a specific use: While the AspriPlus, as a self-priming suction pump, is particularly suitable for installations in the home, the Provedo pump offers a high delivery volume when large quantities of water need to be pumped over small differences in height. The Multigo, with its multi-stage design, ensures constant water delivery over long distances and is ideal for supplying toilets and washing machines with rainwater in the home. In the garden, the Beta pump is an ideal solution as it is robust and easy to operate.
Why WISY pumps are particularly durable
A key quality feature of WISY pumps is their careful workmanship and reliable durability. Thanks to the use of corrosion-resistant materials, the pumps remain operational for a long time. The easy installation of a floating suction filter additionally protects the pumps from abrasive substances such as fine sand particles or sediments in the water. The AspriPlus, Multigo and Provedo in particular are designed for a long service life and minimise maintenance costs thanks to the use of robust materials.
Accessories & retrofitting
WISY offers a selection of accessories to optimise the use and maintenance of the pumps. Floating suction filters prevent sediment from being sucked in and increase the service life of the pumps. WISY also offers pump accessories such as highly flexible suction hoses in various lengths, pressure hoses in individual lengths and other fittings to customise the installation. The ZETA 02 automatic switch is particularly efficient and not only saves energy costs thanks to its minimised standby consumption, but also reduces CO₂ emissions.
