The 20 litre Balance Backpack Sprayer is designed to keep the body in balance while still maintaining good capacity and the exceptional spraying performance that Guarany’s equipment is known for.

Guarany based the design of the Balance on extensive research conducted by the Ergonomics and Safety at Work Laboratory at FEAGRI, the agricultural engineering department at Brazil’s Unicamp University (one of the most renowned universities in Latin America). FEAGRI specialise in ergonomics related to field tasks and Guarany consulted them on the basis that many of Latin America’s field workers are female and existing designs of backpack sprayer did not take the differences in the female form into account.

The resulting Balance design suits both female and male operators. Its wide-based form minimises horizontal pressure on the spine and vertical pressure on the neck and provides ventilation in areas of perspiration. The narrower top also improves manoeuvrability, making moving and turning in small spaces such as among rows in glasshouses or nurseries easier. There are no sharp edges to get caught on surrounding foliage.

The Balance adheres to Guarany’s philosophy of manufacturing robust, comfortable but also precise spraying equipment to maximise the effectiveness of the product being sprayed while minimising any adverse effects on the surrounding environment.

Established in 1923 Guarany have established themselves as a world leading manufacturer specialising in spraying and powder application equipment. Their business is built on a strong ethical philosophy: at the heart of Guarany’s ethos is a respect and care for the natural world. While spraying and fogging disinfectants, detergents, biocontrols and agrochemicals may be necessary, Guarany products aim to minimise excessive usage with clever, thoughtful designs and a range of innovative accessories.

A range of innovative spraying equipment and accessories offering a new way to spray, enabling the efficient application of both liquid, granular and powdered products. The products are designed by professionals for professionals, including cleaning and environmental health experts, groundskeepers, turf maintenance specialists, landscape specialists, horticulturalists and serious gardeners.

As well as a vast array of products for growing plants, trees and vegetables, the Guarany range includes equipment for disinfecting, cleaning and sanitising such as a market-leading disinfectant fogger. The Electric Cold Fogger, along with three different sizes of stainless steel compression sprayer and a Kawasaki engine-driven power mister, is certified by the World Health Organisation as being safe, robust and extremely effective. The specialist disinfecting and cleaning equipment range – as well as many of our standard backpack and handheld sprayers – can be used to spray, mist and fog disinfectants and cleaning chemicals such as hydrogen peroxide, sodium hypochlorite and bleach solutions (check manufacturers’ instructions before using cleaning chemicals) and are ideal for use by deep cleaning services and professional domestic and industrial cleaning companies. They have been developed over many years and build on Guarany’s expertise in spraying equipment for vector-borne disease and pest elimination.

How does the range offer a new way to spray? Because Guarany products provide:

Improved effectiveness – accurate, proven equipment gets disinfectants, fertilisers, herbicides and pesticides exactly where they need to go in exactly the right dosage

Cost savings – Guarany products deliver efficiencies across the board. Much of the equipment is multi-functional. For example simply adding different accessories can mean a number of jobs can be achieved with one backpack. Guarany products are robust and durable and will last for years while accessories and replacement parts are readily available. The accuracy they afford saves money because cleaning chemicals, agrochemicals and bio controls are not wasted.

Better health – they are ergonomically designed reducing operator strains and sprains. Fewer injuries leads to fewer days off too.

Environmental protection – the products adhere to Guarany’s ethical philosophy of protecting the environment: by getting only the exact amount of product needed exactly where it’s needed the surrounding area – and people in it – is not affected. Guarany also has a range of products which are made from bioplastic. The Katu line of backpack and compression sprayers is manufactured from plastic derived from sugarcane and is 100% recyclable.


Guarany is exclusively distributed in the UK and Europe by PSP (The Professional Sprayers People) based in beautiful Sussex and is part of The Spray People Group (SPG) which has has more than four decades experience of providing a range of niche products and solutions to industry, underpinned by in-depth technical know-how and unparalleled customer support. Products are despatched from PSP's Midlands-based warehousing facility, run by another of their group companies, The Fulfilment People (TFP).


PSP has had a long association with our main product supplier Guarany, having drawn on SPG’s industrial spray nozzle experience to work with the Brazilian firm to develop a flexible firefighting backpack a decade ago. This led, in 2019, to PSP forming a long-term agreement with Guarany to be their exclusive supplier in the UK and Europe. PSP is very proud to represent Guarany; quite apart from their market leading products, they are founded upon and guided by strong ethical and environmental principles which have formed the basis of their longstanding success.
