In this episode of Making a High-Volume Parts Washer, Engineering Manager Ben Dickinson walks us through the critical plumbing and pump assembly stage of a large-scale conveyorized parts washer.  Episode 1: Pumping and Pipe Assembly

From welded trunks and flange connections to removable pump skids and integrated VFD control — every detail is engineered for performance, maintainability, and efficiency.
Join us as we take a closer look at how Alliance Manufacturing designs reliability into every system.

Hi. I’m Ben Dickenson. I’m an engineering manager here at Alliance Manufacturing. This is episode two of our large part washer series. Now that our modules are all in position, it’s time to get all the external plumbing in place.

The plumbing is the lifeline of the machine

The things we do on our machines quite frequently as we have pump forward filling our pump for filling is it’s bringing solution from the next stage apart.

We’ll see into the previous stage. So this is from rinse to wash. It helps recover some of the chemistry that gets carried over on the parts and conveyor belt. It also helps maintain the heat of your key processes

All of these lines are connected to our primary feeds. These are multi pass welded trunks. 00:01:11:21 – 00:01:16:28 The reason we have multiple welded tanks on this particular machine is that

the amount of solution being delivered to each spray header is extremely large. By welding these units together, it gives us much higher confidence, in future leak proofing.

So these large pumps and the large pipe trunks that are all affixed to the machine, they are bolted up with flange connections. The reason we have additional flange connections, instead of welding all these components solid, is everything fails eventually, and you’re going to need to be able to maintain these pumps. So what we’ve done here is we’ve actually created splits in the piping in areas that are easy to remove.

And we’ve mounted these pumps on removable skid plates. That actually does two things for us. We can break down this entire assembly for shipment and put it on a truck much more easily. But in the end, at the users facility, it also allows you to quickly remove one of these pumps from the system and drop in a new replacement if needed.

The ease of access is great because it allows you to pull this out, get it somewhere you can actually work on it to a workbench with the proper tools, and you could rebuild one of these units

This vertical pump actually has an integrated VFD in it. So it allows us to ramp up and down the speed of this pump to better match your target process. Parameters. It allows the machine to operate much more efficiently than if it was using simple throttling valves and fixed speed pumps. It also lets us do some cool things where we’re actually flushing out the manifolds between maintenance intervals.

by utilizing the VFD and some new dump belts, we’ve created.
