Hydraulic and pneumatic components: selling by application instead of by part

A buyer of hydraulic or pneumatic components often does not write "I need a 63 bore double-acting cylinder". The message reads "the tipper does not lift fully when loaded" or "the press is slow on the return stroke". So sell by application. Build pages around the machine and the job, such as tipper hoists, moulding machines or packing lines. Answer each enquiry by restating the job before you quote a part. The page uses the buyer's words, so the buyer finds you, and the sizing questions show you know the machine.

How the enquiry actually arrives

Three people send hydraulic and pneumatic enquiries, and only one of them thinks in bores and bar.

The design engineer at a machine builder is sizing a new machine. The load and the stroke are known, and the need is bore, rod, mounting, pressure rating and a drawing. The maintenance engineer at a plant has a symptom. Oil at the rod seal, a cylinder that drifts under load, a noisy pump, a packing line valve that sticks. The need is the machine running by the next shift. The body builder or implement maker knows the job in tonnes, tipping angle and chassis, not in pressure.

What they type into a search box follows the same pattern: "hydraulic cylinder for tipper", "power pack for scissor lift", "pneumatic cylinder for carton sealing machine". The machine comes first and the part second.

Why the part page loses

A page titled "Double acting hydraulic cylinders" with a bore chart competes with every catalogue in the country. It also tells the buyer nothing about whether you understand the machine. A maintenance engineer with a drifting cylinder cannot use a bore chart at all.

Trust comes from seeing the buyer's own machine on your page. The load it carries. The cycles it runs in a shift. The dust at a stone crusher, the washdown in a dairy, the heat beside a furnace door. A maker who writes about those has clearly been there.

What an application page carries

Build one page per machine, in this order:

1. A heading in the buyer's words: "Hydraulic cylinders for tipper bodies", not "Telescopic cylinders".
2. The job as the buyer would describe it: payload, body length, tipping angle and the chassis it sits on.
3. Your sizing questions, set out so they can be answered in one message. Load, stroke, mounting, working pressure, cycles per hour and the conditions the machine works in.
4. A failure you see on that machine, and its cause. On tippers working uneven sites, side load wears seals and scores rods. On packing lines, wet air makes valves stick where nobody fitted a filter regulator. Write only failures your own service team has seen and repaired.
5. Photographs of your part on that machine, used with the owner's permission.
6. The models that fit, each linked to its spec sheet.
7. A named application engineer, and what to send: the nameplate, the mounting and a short video of the fault.

Writing these pages is website content and copywriting work.

The first reply: restate the job, then ask what is missing

When an enquiry arrives by WhatsApp or email, the first reply should prove you read it. Something like this:

"Thank you. You are lifting a 16 cubic metre tipper body on a 10-wheel chassis, and the cylinder stops short when the body is fully loaded. To tell whether this is a sizing problem or a seal problem, please send three things. A photo of the nameplate on the old cylinder, your pump pressure if you know it, and a short video of one full lift. I will reply with the cause I suspect and a model that fits."

Compare that with "Please find attached our price list." The first reply gives the buyer something easy to do next. The second asks the buyer to do your sizing.

Imagine a cylinder and power pack maker in Ambattur

Imagine, as an invented example, a unit in Ambattur, Chennai, making hydraulic cylinders and small power packs. Its website listed "single acting, double acting, telescopic" with a bore chart. Enquiries arrived as "need cylinder price", the team sent back the price list, and the buyers went quiet.

The price list answered a question nobody had asked. A tipper body builder in Krishnagiri needed to know whether a cylinder would lift a body full of wet sand. What a 100 bore cost came later.

The owner sorted a season's enquiries by the machine each one mentioned. Three machines kept coming back. Tipper hoists, plastic moulding machines, scissor lifts. Each got a page with its sizing questions and the failures the service team knew best. The standard first reply now reads: "You are lifting a loaded tipper body and the cylinder stops short. Please send the nameplate photo and one video of a full lift." The price list goes out second, once the model is known. Writing the three pages took the owner's service engineer about two weeks of part-time work, and the first video the engineer shot for a tipper page was too dark to use. Several buyers still went quiet after the first reply, but the ones who answered sent the nameplate photo and the quotation that followed named the right model.

Which applications to write first, and which to leave

Write a page for a machine when two things are true. It keeps appearing in your enquiries, and you have supplied and serviced parts on it. Leave out machines you have never worked on, because the first follow-up question will show it.

Keep the part catalogue and spec sheets as well: the design engineer who already knows the model wants the full table and a drawing, and the application page only brings the enquiry in. If you mainly trade branded valves and fittings that buyers order by part number, start with the catalogue, as our note on selling fasteners, bearings and valves explains. And keep hydraulic and pneumatic applications on separate pages, because the buyers differ.

For search, name each page for the machine and the component together, in the words from real enquiries. Search engine optimisation takes time to pick up a new page, and nobody can promise it a position. The same page works from the first day as the link you send in a reply.

Write one application page from a real enquiry

Open your inbox and find the last enquiry that described a machine instead of a part. Write the page that would have answered it, using the outline above, and send its link the next time that machine comes up. Our industrial components page covers the trade as a whole. If you want help turning your enquiries into application pages and a first reply your team can use, tell us what you need.
