Here you will find the answer to many of our frequenly asked questions on manufacturing and design. MANUFACTURING & DESIGN FAQ Do you quote before proceeding? Absolutely. We can provide an estimate or quote before beginning work, or work on an hourly-rate basis, which will be discussed and agreed before commencement of the job. Can you supply completed parts? Yes. Our workshop is a “1-stop-shop” for machining, sheetmetal fabrication, welding, pressing and polishing: we can not only design, machine, fabricate and test your widget, we can build the box to mount it in. What is a CNC machine? CNC stands for Computer Numeric Control and is a Lathe (makes round objects like a piston) or Mill (makes irregular-shaped objects like hex nuts and machined cavities): we have both in our workshop. The advantages to a CNC machine tool are absolute repeatability and precision – the last part made is as accurate as the first – and high production rates. What is sheetmetal fabrication? We have a dedicated sheet metal shop (working in thin steel sheets to make items like pot sides, bench tops and filter bodies) that handles quantities from 1-offs to high volume production. What other facilities do you have? We have a full welding shop, capable of TIG (stainless steel and aluminium welding), MIG (Mild Steel) and arc, along with a press shop for sheet steel objects. We finish our products either by beadblasting, mechanical polishing or electro-polishing, providing a high gloss finish on stainless steel and non-ferrous metal parts. What is Presswork? Pressing lets us shape or mould flat sheet into complex shapes or “punch” holes or cavities into existing products. We can purpose-build a die to suit your design or use your tooling. Our press shop has deep-draw, high pressure (up to 200 Tonne) and rapid punch presses. Do you make products in other materials? Yes. Although Stainless Steel is our speciality, our workshop regularly processes Plastics, Mild Steel, Aluminium and more exotic materials. Will you build from an existing product? The short answer is “that depends!” If the product is yours and/or is free of copyright/patent issues, absolutely. We pride ourselves on our integrity, confidentiality and our trusted relationship with our customers. Will my product design remain confidential? Definitely. We regularly work on confidential designs, prototypes and production runs for both small and large companies and pride ourselves on our confidentiality and our trusted relationship with our customers. We are happy to provide and sign a non-disclosure agreement if required.

The Series 2-50 Se-Tech Inline Liquid Dispenser has 2” BSP (“50mm”) connections and is suitable for water flows up to 13000 litres per hour at pressures from a “gravity feed” 10 PSI to “hill country” 210 PSI (0.7-14.3 bar). SE-TECH DISPENSERS See also: DISPENSER OVERVIEW DISPENSER IDENTIFICATION SE-TECH 1-32 SE-TECH 2-32 SE-TECH 2-50 SERVICING YOUR DISPENSER DISPENSER FAQ SE-TECH 2-50 The Series 2-50 Se-Tech Inline Liquid Dispenser has 2” BSP (“50mm”) connections and is suitable for water flows up to 13000 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 2-50 dispenser would be suitable for a farm of up to 1250 milking head. In production since 2005, the Series 2-50 was developed following requests for a high-capacity 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 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. Addition rates (“suction” rate) of up to 2% (dependant on dispensate viscosity and density) by volume can normally be achieved with a Series 2-50 dispenser. The dispenser operates only on water flow – no power source is required. This makes for minimal installation requirements, as the 2-50 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), the 2-50 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 dispenser is shown with the optional pipework manifold and an integral mounting bracket is additionally available. The manifold 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. The integral welded stainless steel bracket both holds the manifold in alignment to the dispenser, and simplifies installation of the assembly, providing a flat, rigid surface to the mounting face. This combination makes it simple to install the dispenser, then subsequently bypass the Se-Tech and/or remove the dispenser for servicing, without interrupting the properties’ water supply. Over 95% of all Series 2-50 Se-Tech dispensers are sold with the optional pipework manifold and mounting bracket. 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 and significant piston weight in the 2-50 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.

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). ​ SE-TECH DISPENSERS See also: DISPENSER OVERVIEW DISPENSER IDENTIFICATION SE-TECH 1-32 SE-TECH 2-32 SE-TECH 2-50 SERVICING YOUR DISPENSER DISPENSER FAQ 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.

Singh’s Engineering Services (SES) started in the garden shed in the back of Hurb and Karen Singh’s house in 1979.After operating out of the shed for 18 months Hurb had run out of room, so the business was moved to its first production facility in Mahana Road, Te Rapa. ABOUT US Singh’s Engineering Services (SES) started in the garden shed in the back of Hurb and Karen Singh’s house in 1979. After operating out of the shed for 18 months Hurb had run out of room, so the business was moved to its first production facility in Mahana Road, Te Rapa. Singh’s Engineering was originally an OEM (original equipment manufacturer) for a number of large NZ and overseas-based companies, producing milking cups and other stainless steel products supporting the Dairy industry. One of the products SES manufactured as an OEM was the Carlisle dispenser. Whilst popular – there was little else available on the market at the time – this dispenser had reliability problems and was discontinued. Singh’s Engineering continued to support the machines in use and through this, saw the need for a reliable, New Zealand made dispenser. Singh’s Engineering’s first dispenser: the 19mm unit, was developed and first marketed in the late 1980’s, remaining in production for approximately 15 years. Singh’s Engineering continues to support the owners of these units with parts and service. In 1990, a purpose-built production facility was completed in Mahana Road, Te Rapa, Hamilton, and the company has resided there since. In 1993, production was started on a 32mm dispenser (1-¼” inlets and outlets), which eventually became the Series 1-32. This has remained in continuous production (with ongoing development) and is still recognisable today as our base model. In 1994, the Se-Tech (“Singh’s Engineering Technology”) brand was launched, as the parent brand for our in-house goods such as Inline Liquid Dispensers, Water Flow Indicators and Magnetic Particle Traps. Hurb and the team spend a lot of time talking with our customers and from that interaction came innovation: for example, as the size of NZ farms grew, a larger the dispenser was necessary and so a 50mm dispenser (2” BSP inlets and outlets) was developed, with production beginning in 2003. As time continued, so did developments. The original Series 1 Dispenser remains in wide use. The Series 2 Dispensers were developed to handle more harsh water conditions, for example water which contains higher particulate levels such as manganese, pumice or silt. In response to customer feedback, the Series 2 has a higher dose rate than the Series 1, making it suitable for a wider variety of installations. The latest development in the line of Se-Tech products is the Se-Tech Chlorinator . Based on the 2-32 Se-tech dispenser, it doses extremely low levels of chlorine into a water supply, ensuring safe, effective, low-cost water disinfection.
