SE-TECH 2-32

The Series 2-32 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 an indication of capacity, we expect the Series 2-32 dispenser would be suitable for a farm of up to 600 milking head.

In production since 2007, the Series 2-32 was developed following requests for a dispenser that could handle poor farm water conditions, such as water containing higher particulate levels (such as manganese, pumice or silt) or hard water (generally, laden with iron).

As a consequence, the Series 2 series of dispensers have very wide, flat seals, running on the outside of the piston assembly, in order to provide maximum seal area to minimise overall wear, whilst “wiping” the running surface clean of contaminants and extending life.

Customer feedback during testing resulted in a doubling of suction throughput on the Series 2 range vs. the Series 1 units. An addition rate (“suction” rate) of up to 2% by volume can normally be achieved with a Series 2-32 dispenser.

The dispenser operates only on water flow – no power source is required. This makes for minimal installation requirements, as the 2-32 can be easily installed anywhere there is a water line and a vertical, rigid wall.

Note: Due to the very wide running seals in the Dispenser, rigidity and alignment are both essential on installation in order to maximise seal and operation life.

Whilst longer running life will be achieved with cleaner supply water and dispensate (i.e. the less “grinding paste” the machine processes, the longer it will last), this 2-32 dispenser is designed to tolerate and work with less-than-ideal water supplies and/or more abrasive additive materials such as zinc or magnesium chloride. Of course, the less “grinding paste” the machine processes, the less wear will occur and so running costs will be minimised.

The Series 2-32 dispenser is shown with the optional pipework manifold.

This provides 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 98% of all Series 2 Se-Tech dispensers are sold with the optional pipework manifold.

We recommend an annual service for all Se-Tech dispensers: our busiest service period is found when farms are dried off and the requirement for animal health supplements is at a minimum.

Due to the wide running seals in the 2-32 dispenser, alignment on reassembly is critical: as a consequence, the Series 2 dispensers require a return to our manufacturing facility for servicing.

Our full service facilities 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.
