non collapsable hose suggestion?

[Milkman357]

My WMO pump works great until the suction hose collapses...

Any suggestions? There is a hose used in firefighting.... but I'm looking for something to buy locally....

You need hard suction hose.

I see you are in Iowa. If there is an ag-chem (spray) equipment dealer in your town or area, they would have many choices of suction hose to choose from.

I use a 1/2 inch metal pipe thats 4 feet long screwed into my pump. You can lower it into the waste oil as far as you want and keep the water and crud out.

Hydraulic hose works just fine.
Even junky, old hose works, the steel braid keeps it from collapsing.

Try white marine sanitation hose . West Marine sells it . It comes in 5/8,3/4,1,and 1 1/2".

I have a bunch of sections of hoses intended for use on a trash pump/water pump. They are approximately 15' long and have quick disconnects on each end, one male and one female.

They are 1 1/2" diameter. Also have the pump which runs on 208, 3 phase juice. Make me an offer and they are yours.

Tactor supply, Farm and Fleet or a Grainger will also have what your looking for. You can look up on line for what you need at all three Grainger may give you a few more options though.

Good shopping and post what you decided to use.

Temporay fix.

I needed the pump Tuesday so I made a temp fix...

that water piping they use instead of copper pipe in new homes.... I picked up a small section of it and inserted it into the hose I was using...

I forgot about Grainger....

and the metal pipe is a good idea... just to awkward I'd think.

With my set up Id still need a flexible section anyway.

I'm using and old electric motor to spin a Chevy small block oil pump....it spins at 1700 rpms according to the info on the motor. I think I want to slow it down some too...that would help.

Sounds like you have your problem solved.

temporary fix

I would consider it a temporary fix.... I'm not happy with the bend radius... I'm thinking of cutting the water line into 1/2 inch pieces... then inserting into the clear tubing, leaving at least 1/2 space between pieces. This should keep line from collapsing from suction and give me some added flexibility where I need it.

I think my biggest problem is 1700rpms is kinda fast to be spinning the oil pump.... seems to cause to much pressure.... I'm looking into slowing down my motor now.... I might have togo a pulley driven oil pump.... that just means more $$ but might be better in the long run.

You could always plumb a tee into it with a ball valve to relive the extra pressure back to tank through a hose.
