What's new

The search for a proper recovery pump..

ANSI 12.12.01: Standard for electrical equipment operating in the following:

Class 1 Div 2
Class 2 Div 2
Class 3 Div 1 and 2

Definitions:
Class 1- Gas and Vapors
Class 2 - Dust
Class 3 - Large fiber and shavings
Division 1 - Environments where flammables are likely to exist
Division 2 - Environments where flammables are NOT likely to exist

A properly operating CLS is Class 1 Div 2 while sealed. When you open the tubes it becomes Class 1 Div 1. Basically that makes it a Div 1 apparatus.

Fire standard have zones for Div 1 and 2. Spraying flammable liquids in a spray booth for example: the area inside the booth and 6 feet from any opening is Div 1. The areas outside of this but within 20 feet are Div 2. Build your CLS room so the Div 2 equipment is in a Div 2 area.

So GW I read earlier that you have run the cmep recovery pump. Did you have a problem with it contaminating your gas with oil?If so how to you remedy the situation? I was thinking of put a catch all filter on the input and output of the recovery pump but have been told that a filter on the output side would cause the pump to burn out? Any info would be greatly appreciated.

Yes, there is carry over, which requires an after filter. No problem with pump burnout from a discharge filter.

We are experimenting with alternative filters, but VICI Metronics can supply hydrocarbon filters.

thanks for the reply sunfire and pointing me to that thread. thank you also GW for the reply and the website. so as I understand it the filter from VICI Metronics would need to be replaced after so many uses and the molecular sieve using 4a beads should catch the oil and i can dry them out in the oven and reuse?

Possible recovery pump company have a look

Possible recovery pump company have a look

I was just informed I have a pneumatic pump at my disposal.
The pump I have was used to pump NOS into tanks from a custom race engine manufacturer. This is how I found the pump company.
I have the 3L-ss-25-R model apparently these can be ran on smaller compressors than the haskel this one runs on a 5hp compressor...I have yet to compare the specs to see if it will work. ..
manufactured designed and assembled in usa. Out the box has SS internals on all parts touching fluid, explosion proof, runs on compressed air etc. Have a look at this company catalog and see what you think.

ADVANTAGES OF THE HII PUMPS
Hydraulics International, Inc. (HII) air driven liquid pumps operate
on the principle of differential working areas. An air piston drives
a smaller diameter plunger or piston to provide a pressure ratio.
The pressure ratio is the method of determining maximum outlet
pressure available. Hydraulics International model numbers
reflect the nominal pressure ratio of the pumps.
Hydraulics International liquid pumps operate at a drive air
pressure of 12-150 psi (0.8-10 Bar) and will cycle automatically
when compressed air is first applied to the drive. It will start
cycling at its maximum speed thus producing maximum fluid
flow. At this stage, the pump is acting as a transfer pump, filling
the pressure system with fluid. As resistance increases in the
system (creating backpressure to the pump), the pump will
decrease its reciprocating action. Backpressure in the system
finally balances with the incoming air drive pressure times the
ratio. At this point, the pump will stall and maintain pressure
without consuming any energy. If there is further demand on the
system for flow, the pump will automatically start cycling again.

Air Drive line lubrication not required.

Self-priming for immediate operation.

Compatible with all hydraulic fluids, plain water, distilled &
deionized water, solvents, mild chemicals and most
liquefied aerosol type gases
.

Stainless steel hydraulic body, check valves, and trim are
standard, except -4 and -7 models.


Alternative gases that can drive the pump include nitrogen,
vapor from liquefied gas, pipeline natural gas and sour
natural gas with proper modifications.

Offer a wide range of standard modifications.

Hydraulic pressure is held without energy consumption.

Explosion proof ... requires no electrical power or
connections.


Intrinsically safe.

Compact, lightweight and weatherproof.

Easy to adapt automatic controls.

Contamination tolerant.

Outlet stall pressure pre-determined by the air drive
regulator.

High pressure capability - up to 80,000 psi (5516 Bar).

Ideal for stop-start applications under full load.

Easy to install and operate.

ISO 9001: 2008 & AS9100-2009 Certified Quality Sy

Standard Modifications


“B” Bottom Inlet.
See dimensional data pg.6 and selection table pg. 4. This modification applies only to model
item numbers 10 through 17 and 20 through 27. It is not available for item 28 or 29. It is standard on items 1-9, 18,
19, and 30-35 (which are not available with side inlet).

“D” Distance Piece.
All series. Provides vented, dual seal protection where leakage or fumes from pumped fluid
could attack the air drive section with only the single seal. Specify by adding -“D” after model number, e.g. Model
5L-SS-30-
D
. Double distance piece also available to protect air drive from some high or low temperature liquids.
Specify by adding -“DD” after model number (5L Series only).

“E” EPR (Ethylene Propylene) Static Seals in Liquid Section Only.
All series. Replaces all Buna static seals.
Provides needed chemical resistance if liquid section is used with liquids incompatible with Buna, such as Skydrol.
Standard Ultra High Molecular Weight Polyethylene plunger seal is not changed. It is compatible with Skydrol. Specify
by adding -“E” after model number, e.g. Model 5L-SS-30-
E
. Note: -“D” Modification also highly recommended to
protect air drive seals.

“H” Hand Pump Attachment.
3L Series only. Permits supplementary operation of the pump by hand. Useful in
precise testing or emergency backup applications requiring a hand pump in addition to a power pump. Specify by
adding “H” after model number, e.g. Model 3L-SS-41-
H
.

“L” Low Air Drive Pressure.
5L Series only. Allows operation of the pump with an air drive pressure regulated as
low as 2-3 psi. Also includes “X” modification. External pilot pressure must be 30 psi or more. Specify by adding -“L”
after model number, e.g. Model 5L-SS-30-
L
.

“P” Piped Exhaust.
All series. Enables complete capture of exhaust air or gas from both the drive and pilot exhaust
ports. Permits submerged operation inside hydraulic tanks, and/or piping exhausting gases out of the area for safety
considerations. Exhaust ports for drive and pilot are 1/4” NPT and 1/8” NPT respectively on the 3L and 1-1/4” & 1/8”
NPT on the 7L Series. On the 5L Series, drive and pilot exhaust are joined at a 1/2” NPT outlet. Specify by adding

Alas!

Alas!

I just got off the phone with HII, they have a model that will pull a vacuum down to almost -24hg and will condense vapor to liquid. I mentioned specifically Butane and Propane.

Model 5LG-T-S-4

SS and aluminum internals..
problem is the gas will contact some aluminum. I asked about replacing the Al with 316SS he said it would double the cost of the unit. Unit price is 2160$ Ill gladly pay 5k for an all SS explosion proof pump that WILL pull a vacuum. He did say there would be a "Horrendous lead time" to quote exactly which isnt encouraging. I did not ask how long that equates to... lol I think Im going to order a custom one and see how it goes. If all goes well Ill incorporate that into the new system... ;) Although still useful the model I have now will only do liquids....


Respectfully,

FE

Im told they would need a blanket order of 50+ pumps to replace the Al with SS on all wetted parts and that the price would increase 2.6 times. to approx 5800$ x 50... Damn, back to the drawing board. Im seeing what parts would need to be replaced and Im going to talk to my machine shop and see if we can have them made ourselves on the CNC machine. If so I may be able to get part kits made to do the upgrade ourselves. The pump isnt that big and there is no way that there are 2,000$ + worth of SS that would need to be added to replace the Al inside. ... Wonder if a similar parts kit would be possible for the haskel 59025.. anyone have a wetted parts list? thoughts, opinions?

Developments as they happen LOL I told them I needed the pump to pull to at least -20hg..

so now I was asked to look at model 5G-TS-7/14…

all stainless steel internals with standard Viton O-rings in the gas section and Carbon graphite filled Teflon main seal. We would have to perform further testing but it may meet your vacuum requirements.
sounds like it has potential lets see...

I'm trying to stay with ya. The specs for that one say 30 PSI minimum inlet pressure. Does that matter?

The 30 psi minimum will be needed to achieve the corresponding output pressure. To get 1350 output you would need 30psi inlet.

They'll pull vacuum if the outlet pressure is low.

I have lots of experience dealing with hydraulics international. Very expensive especially for seal kits. They are also not cannabis friendly which will come to light during warranty concerns. As Haskell has shown an interest in our industry I would look there.

The VICI can be recycled a few times for water by baking, but not as easy with oil. VICI has a recycle service but options are limited.

4a is too small a pore for hemp seed oil. Not sure what VICI uses, but 13a might be a better choice.
