New tanker

[P.O.T]

New tanker week or so ago.
Question about filling, will fill ok with watery slurry but if it gets thick at all really struggles, takes an age wont fill up to sight glass even. Alot of pressure build up when released and no thick slurry in pipe when taken off. Old abbey 1300 filled thick stuff fine, so thick a couple of time wouldnt run out of tanker in neutral!!

 

[michael N123]

are you running it at the correct rpm ? Could the new pump be 1000

 

[Boohoo]

What size of pump is on it and what speed are you running it at? I'd try reducing the pto speed or using 2 pipes. Big pumps and 6 inch pipes don't work well in thick slurry

 

[P.O.T]

11000 pump running it at 300ish rpm
Pretty sure pump is 540.

Fit a turbo pump , you will never be without one again ! Full loads everytime thin frothy slurry / thick crap , every load brim full . Over the life of a tanker it will more than pay for itself

300 is too slow , always work at 380 when filling .

It will be a 540 pump with a recommended speed of 350rpm, but this will be too high for some situations with a single 6 inch pipe. Try 2 pipes or filling on tickover, if the tanker still doesn't fill full there's something wrong with it.

Tick over will suck very little . If you want vacuum then Rev it up.

An 11000 litre pump will fill on tickover. Too many revs is more often the problem than not enough. You only want enough vacuum to fill the tanker, you don't want the slurry to expand in the tanker.

 

[awkward]

can a turbo filler be fitted at inlet or does it need to be on lasyarm. what price would one be

 

[Mursal]

And throw the water hose on the suction pipe for a few fills, especially around the joints, just to test, it might be a cheaper option ...........

 

[Iron150]

Could the pump bw worn out? Its a second hand tanker from the picture

 

[Mursal]

Might be new to him?

 

[P.O.T]

Seem to build up alot of pressure when sucking. All seem air tight. Tanker is new to me, 2014. How would you know if pump wasnt right?

 

[jthomsonagri]

Is the gate valve opening up fully? They have a habit of filling up with straw and silage around the top of the flap.

 

[jthomsonagri]

You certainly have something wrong as it should fill up to the glass. How deep down is the slurry in the pit?

 

[P.O.T]

Yeah gate valve is opening fully. Fills full when watery slurry or out of effluent tank. Tank 6 feet deep

 

[jthomsonagri]

That rules the valve out then. Is it 6 foot to the bottom of tank or to the top of the slurry? Also do you have a gauge on the tanker to show what pressure you have? If so what vacuum are you achieving?

 

[ollandroverman]

Suction hose could be internal collapsing under high vacuum levels when loading with thicker slurry. Ideally you would have a working vacuum gauge on your tanker which would eliminate a lot of your guessing.

Get someone to drive forward slowly during filling to pull end of pipe out of slurry and see if there is suction.
