Introducing the EZ-FLO commercial range.

The EZ-FLO High Capacity Main-Line range covers three horizontal models and four vertical models to give you ultimate placement possibilities – from situated in a large underground valve box to the back of the pump shed. We also have a range of light-commercial models, suitable for smaller applications.

Not JUST for fertiliser.

You can use a huge range of liquid and water-soluable products with EZ-FLO’s commercial range
Soil Wetters

Effectively improve hydrophobic soil and stop wasting water to run off. Thanks to EZ-FLO, it’s easy to get soil wetters where they’re needed – the soil.

Soil Improvers

Keeping soil healthy has never been easier. Utilise every drop of water by injecting  beneficial soil improvers to exactly where it’s needed – the soil.

Seaweed Products

The EZ-FLO is perfect for applying much loved seaweed products. It’s as simple as filling and adjusting to your preferred dilution rate.

So much more

Bio-Stimulants, Iron supplements and more. The EZ-FLO is changing the way Australian businesses fertilise.

Businesses are using EZ-FLO systems across the globe to produce exceptional results. Read below to find out just a few of the reasons why EZ-FLO is a favourite in the commercial industry.

Better, Healthier Plants

Accurate microdosing of important nutrients and fertilisers will allow you to improve the health of plants and crops! Forget feeding every 6 weeks, you can now provide nutrients every time you water.

Stop Wasting Expensive Fertiliser

Research proves Microdosing reduces fertiliser use by up to 60%.

Easy to fill

Our High Capacity models have separate fill caps that make filling simple.

Disperse a Huge Range of Products

EZ-FLO isn't just for liquid fertilisers. You can disperse a huge range of liquid or water-soluble products.

From Slow to Fast

EZ-FLO tanks allow you to adjust how much fertiliser is being dispersed. EZ-FLO tanks can also inject at extremely low flow rates, flow rates low-enough that they’re suitable for drip irrigation (nothing else compares!).

Connect into your current system

EZ-FLO is simple to integrate into your current system. You can do it yourself, or have a professional installer install EZ-FLO for you.

What is Fertigation?

In this video, we show you how EZ-FLO injection systems operate, an example installation + more.

High Capacity Mainline Units

EZ-FLO High Capacity Main Line Systems attach directly to your pump discharge or downstream of your backflow device and will inject directly into overhead sprinkler and drip irrigation systems.
Every time you use your irrigation system, EZ-FLO releases small, precision doses of water soluble or liquid fertilizers into the water stream automatically.
One system will feed through both sprinkler and drip irrigation zones without the need to make any adjustments or nozzle changes to compensate for water flow or water pressure.

The High Capacity versions of our Main-Line Systems include a proprietary fill system allowing the tanks to double their water soluble capacity. With this fill system, there is no need to remove the proportioning cap to add products.
The High Capacity models also feature a larger drain valve, automatic air vent valve, and a schedule 80 PVC or Glass Fibrewound body for added protection and durability.
These units have no moving parts making them very reliable, dependable and maintenance-free.
All systems require a CBV, ball valve coupling adapter, to suit the size of the irrigation mains where you want to inject. A variety of sizes are available ex stock and we can also custom make one to suit your needs.

The EZ-FLO High Capacity Main-Line range covers three horizontal models and four vertical models to give you ultimate placement possibilities – from situated in a large underground valve box to the back of the pump shed.

Model selection is based on time required between refills. For example, many Councils want a monthly refill, hence if they estimate that a sports field would consume 100 Kg of water soluble fertiliser each month, it would follow that either the horizontal EZ 025HC (95 litres) or the vertical HCV112 (112 litres) would be suitable. Some Councils actually select the capacity to refill on a quarterly basis and yes we have systems suitable.

EZ-FLO systems are ideal for professionals who service projects on a contractual basis.
AN EZ-FLO never runs ‘dry’ because the fertiliser is displaced by water and at the end of its cycle it is full of water only, so if for some reason a scheduled refill cannot be met there is no concern for seals or pumps failing.

Frequently Asked Questions

What fertilisers can I use?

Virtually any type of liquid or water-soluble fertiliser or liquid product can be used in an EZ-FLO unit.

Is there any maintenance required?

In normal operating conditions, the EZ-FLO requires no maintenance.

There are zero moving parts to wear out and no electrical components. EZ-FLO units work using existing water pressure from your system.

Why EZ-FLO is better than the rest

Consistent and Accurate Metering – other systems can deliver dangerously high levels of fertiliser or chemicals in the first few minutes, and then drop below the ideal feeding range for the remainder of the application cycle. With EZ-FLO, your landscape receives consistent micro-doses of fertiliser or nutrients which is proven to be the best way to feed your plants.

Adjustable Feed Rates – Various precision settings, from 0.1 ml per litre for constant feeding to 10 ml per litre, enable you to achieve desired feed rates for just about any fertilising or control situation. Micro-dosing also eliminates the chance of “burning” your plants or staining buildings or walkways. Most other systems are difficult to adjust or are non-adjustable.

Automatically Adjusts to Pressure and Flow – Since there are no moving parts, there is no pressure loss when using our system. EZ-FLO systems can proportion on a little as 9.5 litres per hour flow at only 5 PSI (35 kPa) water pressure. This makes EZ-FLO particularly useful on irrigation systems with low water pressure, on long piping runs or when installed on a low-flow drip or other subsurface irrigation zones. Most other systems do not adjust automatically or have the wide flow range as EZ-FLO.

Availability of Products – EZ-FLO can use a full line of organic, natural and synthetic fertilisers as well as supplements (bio-stimulants, mineral supplements and surfactants) in landscape and grower applications through our recommended supplier links . These products are available a la carte.

Ease of Use – No pre-dilution of water solubles required. No annual maintenance. Longer service life. Fewer refills for the equivalent size property. Greater landscape coverage available ( 5 to 323 litre units)

What can I connect to EZ-FLO?

EZ-FLO systems can be used with all sprinkler and spray heads, micro-spray heads and drip and subsurface options without the need to adjust the system for zones with different end devices (i.e. spray heads vs. drippers).

EZ-FLO adjusts automatically to water flow in any zone even if there are different pressures present in that zone. For example many drip zones have pressure reducers in order to protect the dripper heads.

Competing systems do not have the same ability to easily address these different flow and pressure attributes with a single unit.
