NanoDose™ Aggitation Dosing Unit

A dosing pump and 100 L tank with built-in recirculation mixing, for chemicals that settle out if left standing. Chemicals not included.

What it is for

Dosing chemicals that are mixed into water as a suspension or slurry – most commonly hydrated lime (lime milk) for pH correction, or a coagulant made up from powder. Left standing, these settle to the bottom of a tank, so the pump would draw a weak dose one day and a thick, blocking sludge the next. This unit keeps the mix uniform so every dose is the same.

How it works

The recirculation pump continuously draws from the base of the tank and returns the flow through the NanoJet EcoShear™ nozzle inside the tank, turning over the whole volume. The dosing pump draws from this evenly mixed tank and injects a set, adjustable dose into your raw water line.

What’s included

• Etatron PKX analogue dosing pump – solenoid diaphragm pump, output set by hand on the dial (1 L/h at 5 bar, up to 5 L/h at 7 bar), IP65, NSF certified. Supplied with its installation kit: 2 m discharge tube, 2 m suction and bleed tubes, foot filter and injection valve.
• Peripheral recirculation pump (220 V, 0.37 kW, QB60) – draws from the base of the tank and returns the flow through the mixing nozzle.
• NanoJet EcoShear™ mixing nozzle – mounted inside the tank, keeps the whole volume turning over so solids never settle or cake.
• 100 L chemical dosing tank – choose Blue for outdoor installation or Clear for indoor installation (lets you see the level at a glance).

Not included

• Treatment chemicals.
• Why chemicals are separate: treatment chemicals are heavy and expensive to ship, so it is usually far cheaper to buy the recommended chemical from a supplier near you. We’ll tell you exactly which chemical and strength to buy, and it is also available from us as a separate product.
• Installation (available on request).

Good to know

• For a clear liquid chemical that does not settle (such as sodium hypochlorite), the simpler NanoDose™ Dosing Unit is all you need.
• Dosing lime or a coagulant creates a settled sludge downstream. Plan for settling and filtration after it, for example the NanoJet™ STANDARD Iron & Sludge Removal Kit.
