Steam driven pump 2

[dbday]

Hi,
I have been given a specification sheet showing a direct acting steam driven pump.

The size is given as 11" x 8" x 18"
Is it likley that these numbers mean anything ?

Also
The speed is given as 18 DSPM - what does DSPM mean ?

I have not been given the make of the pump, and I just trying to understand what I have been told.

Thank you for any help.

11" x 8" x 18" means 11-inch steam cylinder diameter, 8-inch water cylinder diameter 18-inch stroke. DSPM means Double Strokes per Minute. Must be a Duplex unit. Where are you going to install this beast? Is it of recent manufacture? I though they went away in the 30’s.

Thanks Steve,

Thanks Steve, that helped me, having looked around the internet a bit, and with your reply, I can only agree that the machine is a bit of a beast from the ark.

As for what is being done, the project is in Indonesia and the fluid being pumped is Vac Residue oil, I don't know if it is at the design or procurement phase.

I have seen this type of fluid being pumped with normal triplex and quintuplex pumps so I don't know why this machine has been selected.

Once again, thank you for your help.

Wow, I haven't seen one in years (except for the small one that I intend to make into a desk ornament one day) but the last one I saw was running and pumping water. Sorry, but if I wanted to buy one, I don't have any idea where to start looking, but with the wonders of Google:

You gotta be kidding.

I spent part of my apprentice training fixing those things.

They are some of the earliest pump designs in existance. I believe G & J Weir invented the firsts ones.

They were common on board ships even up to the 50's

One of the nearby Refineries still have a couple of those in operation a few years ago when I was last in there. And another Refinery I did a job at had quite a few in a partially abandoned pumphouse, believe some were still in use.

Holy dinosaur! The previous refinery I was had a few of these in service - they became an emissions nightmare and subsequently went away. The site I'm at currently still has one or two abandoned in place.

I found a small one in an abandoned mine I was exploring and took it home. It is ~24 inches long and weighs about 100 lb. When I retire (if I retire) I intend to disassemble it and chrome plate it and use it for a desk ornament (after, of course, I reinforce the desk.) The mine drove it with air and used it to pump the water out. Most that were in operating plants when I started out in the industry were steam driven, and oil from the exhaust was everywhere.

Wow! They're still being manufactured? !!!!!
