Gardena 3700/4 Garden Pump with Autoclave

Gardena 3700/4 garden electric pump with autoclave is a sustainable and powerful solution for automatic home and garden water supply. Easy to install, the autoclave becomes part of the hydraulic system and allows you to use rain water or well water to irrigate your garden or as service water at home, for example for bathroom appliances.

The 3700/4 Autoclave develops a power of 4.1 bar at 800 W and can drain an amount of water up to a maximum of 3700 liters per hour. Its maximum suction depth is less than 7 meters. In addition, it features a 19 liter water tank with EPDM membrane which is low-maintenance and can be easily filled or emptied manually.

This article is particularly suitable to irrigate, increase the pressure, take or suctioning tap water, rain water or swimming pool water containing chlorine. It is not suitable for salt water, corrosive or highly flammable materials or food.

It is equipped with a thermal switch, which protects it from overheating. Moreover, it is equipped with a non-return valve and threaded inserts made of high quality brass. These aspects not only increase its duration, but also facilitate the use of the product as a reliable and low-maintenance permanent element in the hydraulic system of your home.

Lastly, the additional G1” double connection makes the 3700/4 autoclave even more versatile.

The Gardena pumps stand out for the German engineering design, which ensures optimum performance in terms of reliability, results and ease of use.

These pumps are suitable for transferring water (from a cistern to another, for example) or for small-scale flood irrigation in gardens. We do not guarantee the suitability for the combined use with sprinklers of different typologies or various real irrigation systems, (as they require the contribution of a qualified technician and a number of calculations in terms of flow rate, head lift, pressure, pipe diameters, valves, nozzles, and so on), which may require more specific types of pumps for water systems.

Technical Features

The compact GARDENA autoclave not only saves space, but also impresses thanks to its robust plastic body reinforced with fiber glass and double ceramic seal system with stainless steel pump shaft.

Practical gauge, always shows the current pressure in the 19 liter tank and thermal switch.

Quick coupling: coupling for irrigation hose with 33.3 mm (G1") diameter brass connection thread.
