Side Channel Pump - no delivery
(OP)
Hi All
Recently we purchased a LPG bobtail with Pompetravaini side channel pump. it is driven by hydraulic motor. The problem is, when i try to deliver LPG through pump, i get high noise, hydraulic pressure is reaching upto 150 bar, but there is no delivery from pump. the pressure gauge in pump discharge is not even moving one bar higher. I tried to check the hydraulic motor, by reversing direction, even then no output. I seriously doubt is the pump is blocked mechanically, or what else might be the reasons for not getting discharge?

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Why?
Absolutely no idea, but I think you need to strip it down and see what is seized or broken. Take the motor off first and see if it goes round. Then see if the pump shaft will turn with the motor off.
I can't find any details on this pump so unless you provide a few more details we're not going to get very far, hence the rather short answers given to date.

On the other hand, supplier claims he tested it successfully. Seriously puzzled.

Or just buy another one?
No idea which is cheaper overall

So are we, it would be interesting to know how the unit was checked for correct rotation before it was put into service.

Between"testing" it and now something has broken or got jammed in the pump. Stop messing around and dismantle the pump. There is no mysterious "protective fluid".
Why on earth do you think the manufacturer has done this? Did someone tell you or are you just clutching at straws to prevent you taking the pump apart?

Agree with LittleInch, dismantle the pump is your only option

Send it back to the supplier with a please explain note attached.
I can see any connection between rust and the mechanical damage to the mech seal.

Clearly anything with broken bits of metal wandering around it could get stuck, but fall out when you dismantle it. Those bits looked quite big.
Difficult to know exactly what we're looking at without a diagram, but hope you can fix it and now follow the pump maintenance and startup instructions for a long life...
