SE-TECH 1-32

The Series 1-32 Se-Tech Inline Liquid Dispenser has 1-¼” BSP (“32mm”) connections and is suitable for water flows up to 6000 litres per hour at pressures from a “gravity feed” 10 PSI to “hill country” 210 PSI (0.7-14.3 bar).

As a sizing indication, the Series 1-32 dispenser would be suitable for installations from small runoffs to a maximum of 600 milking head.

The Series 1-32 has been in continuous production since 1993: all developments made since its introduction are fully retrofittable to all units.

As the dispenser operates only on water flow – no power source is required – the 1-32 dispenser can be easily installed anywhere there is a water line, whether in a pump shed, on the side of a building or, as we’ve seen more than once, bolted to a fence post!

Note: If mounting outside, we do recommend the dispenser be installed in a shaded area to minimise exposure to UV: a galvanised iron “sunshade” works very well.


This dispenser is suited to installations where a clean water supply is assured (no abrasives in the water supply) and products to be dispensed are well mixed to minimise abrasiveness.

The Series 1-32 dispenser is shown with the optional pipework manifold.

The pipework manifold includes an inline coarse (mesh) filter, a non-return valve, isolation and bypass valves, along with quick-release couplings between the manifold and the dispenser proper. This makes it simple to install the dispenser, then consequently bypass the Se-Tech and/or remove the dispenser for servicing, without interrupting the properties’ water supply.

Over 90% of all Se-Tech dispensers are sold with the optional pipework manifold.

The Se-Tech Series 1-32 dispenser is designed with the Kiwi Farmer in mind: all parts are available and can be fitted/exchanged by the owner on-site.  However we do recommend that all dispensers are periodically sent into us for a service where we will check all parts for wear, runout and alignment.

Parts can be ordered by email or by phoning us on 07 8493 108 here is an “exploded” parts list of the unit (PDF format) for quick reference.

Full service facilities are of course available via our workshop: we offer service turnaround times from overnight to less than three hours with a booking: please call us on 07 8493 108 or email us to confirm a service booking.
