Pumping Sauce?

A sludge pump like they use in Dairies and Feedlots would do it.

Or even a septic pump, but if the sauce is edible, I wouldn't get a used one.

"... I wouldn't get a used one"

If it is super thick, maybe a piston pump like for pumping wet cement

The piston pump is a good suggestion, but a variety of positive displacement pumps can do the job. We just assume sauce is in food processing.

A food grade pump, of course. Duh.

Sorry, I'm here in the US, where there are lots of regulations. There are many pumps that would successfully pump sauce. Is the sauce intended for human consumption, or are you creating a slurry of sauce that is beneficial to vegetables, to be composted and sprayed on gardens. Without more specificity, it's impossible to tell. Where are you pumping the sauce, into canning jars or do you want it atomized? Do you want a continuous pump, or one that pumps a given amount and stops in a predetermined pattern? etc.

Any positive displacement pump will work. And even some centrigual pumps might. But since you provide no useful information, that's all you get.

"Very viscous sauce" is a very poor description from which to work.

Is that viscous, viscose or vicious? [Just checking - to make sure we're all singing from the same song-sheet ].

Why would you not recommend that the term "pumping sauce" be used as a search criteria in an internet search engine ?

Particularly if you were seeking a solution to pumping sauce.

Oddly, top hit on Google;

CR4 - Thread: Pumping Sauce?

Proving enough curious engineers can 'out hit' an "eat blog" and a Patent - even Jessica Alba.

You could use a Wright or Waukesha pump. J.O. Galloup offers them, there is a rep I have dealt with in Michigan named Bob Moriarty. They could get you the pump you need. I have worked in the food industry and had to order these pumps for "our" thick syrups and so on. They have 015, 030, 060, and more... Also, consider heating that sauce of yours to help it become more manageable. Worse case, I believe you could use a diaphragm pump.

For my own information, what is the down side of using the diaphragm pump? Thanks.

I don't see a down side... it would run off of air and not electric though??

only down side I would see is not having the air in the plant or whatever their situation is... I was just trying to think of the electric pumps I know of...

Thanks. I will agree, not having air supply would be a disadvantage.

A positive displacement pump running very slowly.

When you are ready to provide some specific information on the viscosity and possible non-newtonian characterstics as well as the desired flow rate and discharge pressure then a more detailed answer from one of us should be forthcoming.

Is ketchup Newtonian or thixotropic? I suspect the former, but elephino.

Psuedoplastic (shear-thinning). That's why it takes a takes a hit to get it flowing.

FOR VERY VISCOUS FLUID PUMPING THE POSITIVE DISPLACEMENT PUMP WILL BE USED SUCH METERING PUMP

And please get rid of the all-caps, too.

Most recommended is a positive displacement pump, but that implies that one should have a compressed air supply on the plant. If no compressed air supply is available, then another option one could have is to use a rotary lobe pump. SRU range of rotary lobe pumps from Alva Laval is probably your best option. http://www.alfalaval.com/solution-finder/products/sru-rotary-lobe-pump/pages/sru-rotary-lobe-pump.aspx

Hi Old Sat,

I have the following two comments:

1-Handling glue during winter season is not easy,sometimes you need to worm up the pump when starting,that is why a single screw Pump with heating jacket is more suitable than the diaphragm Pump regarding this application.

2-Some authorities dealing with health are insisting to provide design features to help cleaning the Pump in place,CIP,using steam and i think the diaphragm Pump has no such features.

Sayed-

I have used both the moyno screw pump and the Wilden double diaphragm for pumping glues and have had better performance with the double diaphragm units. The glues ranged from water thin to those such as animal glues, thick heavy duty wall paper pastes, and other unflowable at room temperature materials. For example, wall spackling with it's thixotropic properties is very fluid compared to those glues pumped at times.

My preference is still for the double diaphragm since we experienced far fewer problems with maintenance, range of pumpable viscosities, shredding of internal parts, and ability to pump materials at lower temperatures.

When temperatures were extremely low best results obtained were to heat the materials through the jacket of the storage tank and not the pump.

Double diaphragms are available with heating jackets.

Never had to heat Elmer's Carpenter Glue to pump it into a tank truck even when temps of the materials were low. At the receiving location they initially unloaded with Moyno's but changed to double diaphragms due to problems unloading cold glue and also shredding of the rubber. This was usually at least 2 tank wagons a day.

Double diaphragms can be made with provisions to clean in place with steam. Even better than that they can easily be removed from the piping system simply by loosing two clamps which hold them into the piping. Cleaned out of the system where all parts can be removed from the pump and cleaned as individual parts is preferred to cleaning in place. The pump is then reassembled and put back into the piping system.

Hi Old Salt,

Thank you for the information that you have added,it added to me other application where the double diaphragm pump can be used.I just want to tell you that the mohno pump with water heating jacket is a known application in wool carpet manufacturing facilities to pump glue.

Use a Versamatic FDA approved diaphragm pump. http://www.versamatic.co.uk/fda.php?style=E4

Both in the dairy and baking industry I have seen Waukesha gear pumps used. Others make these pumps too. The advantage is that these kind of 'sanitary' pumps break down easily for cleaning/repair.

The neatest thing I saw was one of these pumps used to pump bun dough through a flat plate heat exchanger. What a mess it made when the mixer guy would make a mistake or the chilled water shut down!

Regardless of the pump type, if the sauce is for human consumption, the make sure the pump is the "oiless type", otherwise the sauce will become tainted.

Waukesha gear pumps, have a gearbox full of grease, not a problem

That's why seals & food grade lube was invented

There is an air gap between the gearbox and the pump housing!

So There!

This has been a delightful exercise in imaginative humor. You guys DO realize this is a homework question, right?

He'll know better next time.

wow - what a respose to the pumping of a viscous substance - i would say if you have air use a diaphram pump and if you don't want to bother with air pressure use a variable speed peristaltic pump

I think you guys need to lay off the sauce!
