Before and after

From worn out to ready for work

Left: a drive end as it arrived in our workshop. Right: the same type after our overhaul – stripped, cleaned, measured, repainted and rebuilt. This is what you get back when a machine leaves Hilversum.

Open crankcase of a homogeniser with crankshaft and connecting rods

Step 1 · Drive end

Stripped to the last bolt

Every machine is taken apart completely. Crankshaft, connecting rods, crossheads and bearings are measured and replaced where needed. Seals and the lubrication system are renewed, so the drive end is ready for many more years of production.

Step 2 · Pump end

A pump end that holds its pressure

The pump end decides how well your product is homogenised. We fit new plunger seals, valves and valve seats, and choose the cylinder block execution that matches your capacity and pressure. Parts come from our own stock of more than 15,000 items.

Step 3 · Motor and drive

Motor, belts and hydraulics checked

The main motor, belt drive and pulleys are inspected and aligned. Where the machine has hydraulic homogenising valves, the hydraulic unit is serviced and tested at full pressure.

Step 4 · Control

Clear readings, safe operation

Gauges, pressure indicators and the emergency stop are checked and replaced where needed. You see stage 1, stage 2, inlet and oil pressure at a glance – just like on a new machine.

Step 5 · Test run

Tested before it leaves Hilversum

Every refurbished machine is test-run in our workshop. Only when pressure, temperature and running behaviour are right does it go on the truck. On site in the Netherlands, Belgium and Germany, our own engineers can install and commission it.

Every size

From the compact MC7 to the heavy G55

Large or small, every machine gets the same treatment. Two examples from our workshop.

Heavy duty

Gaulin G55

One of the largest machines we rebuild. Crankshaft and gearbox are overhauled, the plungers get new seals, the main drive gets new belts and the pump end is rebuilt – until the machine is ready for production again.

Compact

Gaulin MC7

Small machine, same care. The compact MC7 is ideal for smaller lines and pilot plants. We rebuild the pump end, renew the lubrication and oil cooling and fit new gauges – so it runs like it did on day one.

Questions

Frequently asked questions

Which refurbished machines do you supply?

Mainly Gaulin MC18 and MC45 homogenisers, rebuilt in our workshop in Hilversum. Ask us for other types – our offer changes regularly.

What is replaced during refurbishment?

All wear parts of the pump end – plunger seals, valves, valve seats and seals – plus any drive-end parts that are out of tolerance after measuring. You receive an overview with your quotation.

How quickly is a refurbished machine available?

Usually much faster than a new machine. The exact time depends on the machine and the execution you need – we tell you in the quotation.

Can you install the machine at our plant?

In the Netherlands, Belgium and Germany our own engineers install and commission the machine. Elsewhere we support your team remotely or send an engineer on request.

Can I trade in my old homogeniser?

Tell us which machine you have. Depending on type and condition, we can take it into account in your quotation.

Looking for a refurbished homogeniser?
