Self-Draining Liquid Fertiliser Tanks
The Polymaster Self Draining Liquid Fertiliser Tank is engineered for complete washdown between mixes, so nothing carries over from one load to the next and no liquid fertiliser is wasted. The 33,000L holds a full tanker load on farm and sizes come ready to go with stainless steel camlock fittings and a sight tube level indicator fitted as standard.

Why Choose a Self-Draining Design
Switching between fertiliser mixes or seasons usually means some residue carries over in the base of the tank.
Polymaster’s Self-Draining Liquid Fertiliser Tank empties, so the tank washes down clean between loads with no contamination risk and no fertiliser left behind to go to waste.
At 33,000L, it holds a full tanker load, so bulk deliveries can be unloaded direct to tank without needing to split the load.
The 33,000L is the only size that fits a full tanker load; however, we offer 23,000L and 28,000L options.

FAQs
Frequently Asked Questions
Everything you need to know about Polymaster’s long troughs range, from sizing to maintenance.
What are the benefits of a self-draining liquid fertiliser tank?
A self-draining tank empties completely between fills, so there is no residual mix left in the tank to contaminate the next load or go to waste. This is most useful on farms running more than one fertiliser mix through the same tank, or switching products between applications.
How does the tank's design allow it to drain completely?
The tank uses a sump and a 2-inch stainless steel outlet with a ball valve at the base. This configuration is what allows the tank to empty fully, rather than leaving residue sitting in the bottom the way a standard flat-bottom tank can.
How do I maintain a self-draining liquid fertiliser tank?
Use the sight tube level indicator to keep track of what is in the tank, and drain it fully through the base outlet between different fertiliser mixes to avoid carryover. The 600mm vented screw lid gives easy access for inspection or cleaning.
What material are self-draining liquid fertiliser tanks made from?
Every tank is manufactured in Australia from heavy-duty, UV-stabilised polyethylene, rated to hold liquids up to 1.5 specific gravity.
