FIM Series Frequently Asked Questions

How does the closed-circuit flush work on the Furrow Injection Modules?

It prevents all agitation and regulation bypass from returning to tank by diverting the flow through the delivery system and out of an excess flow port.

Why do you need a manual pressure relief valve?

The manual pressure relief valve is in place to allow a maximum system pressure to be set. This prevents over pressurising products to ensure their effectiveness. This does not bypass in normal operation.

How does the bypass regulation work?

Bypass regulation allows excess flow to return to tank without creating agitation which eliminates foaming issues in low levels of the tank.

How is the pass return different to agitation return?

Agitation return is designed to create turnover in the tank to maintain product suspension. Bypass return allows excess flow to return to the tank without creating agitation.

I don't want section control this year, but would like to add it in the future. Can I add to my current system or do I have to start from scratch?

All FMSA in-furrow and spray modules are designed to be upgradable. It is quite simple to add on desired features after initial purchase. FMSA strives to make our products work for any level of operation and grow with the needs of our clients without excess cost.

Can I just use a tank mix or do I need an injection unit?

It depends on the situation. In today’s liquid fertiliser market, a lot of products are compatible for tank mixing, however, injection modules are available for any situation that involves products that can’t mix and/or a second delivery point to prevent product mixing prior to the furrow.

How do I know if the products I'm using can be mixed?

Best option for finding out product compatibility is to speak with your agronomist or supplier. Here at FMSA we do have access to a range of chemists and the ability to test rare mixtures if needed.

Friction Flow Frequently Asked Questions

What is Friction Flow?

Rather than a small restriction point, like an orifice plate or in line restrictor, Friction Flow uses larger internal diameter tubing over a distance to create an accurate and even metering system. Friction Flow is manufactured from the highest grade nylon for its chemical resistance, UV stability, and its wall strength to prevent kinking, crushing or internal distortion.

What stops Friction Flow from blocking?

Larger internal diameter and faster flow of liquid through smaller delivery lines to secondary delivery manifolds minimises the chances of blocking when using more complicated liquid combinations.

What size does Friction Flow come in?

Friction Flow comes in three standard sizes internally; 1.2mm, 1.5mm, and 2mm. Each tube size maintains the same external width of 6mm.

What filter size is required to be used with Friction Flow?

Due to the larger internal diameter of the Friction Flow tubing, systems can run as low as 16 mesh of suction filters with no pressure filters required. It is recommended that all filter sizes be discussed with FMSA prior to operation or installation.

Do you need covers for check valves?

No covers needed. FMSA’s check valves are designed to work in dusty, dry conditions without jamming or leaking.

Do you get drips out of the tubing?

Friction Flow when paired with FMSA’s manifold system holds liquid to the tip of the tube with no drips or dribbles.

Do you get leaks on the non-drip caps?

FMSA’s non-drips are designed to work under high pressures with the same products in spray applications without leaks. When running with Friction Flow pressure is lower at application.

Agitation Frequently Asked Questions

Why do I need Agitation?

Agitation maintains product suspensions. Without proper product suspension, consistent product mix can’t be guaranteed. System blockages become less likely with proper product suspension.

How important is Agitation?

When product blends are involved agitation is as important as proper metering. Without agitation it is difficult to ensure product is staying suspended and mixed in the tank. When product falls out of suspension, in furrow percentage and rate is affected and blocks can become a concern.
