Can you explain what happens when you select high pressure on the crossover? Does it just open a valve or does it actually start the high pressure pump spinning?
It diverts the water flow through a restriction , causing high pressure with a lower volume of water. This is governed by a 50bar safety valve which opens if pressure exceeds 50bar. This happens whilst also making low pressure at a high volume. This is a 2 stage pump. World series twin 3010. 3000 ltr of water per min at 10 bar (low-pressure)
Yes you're correct. We don't pump from salt water as nowhere near the sea. It would work if you did but would have to flush out with fresh water after and not advised. The LP impeller is cast aluminium the HP is stainless and the body is aluminium.
Can you confirm where the primer hose attaches to please, is it attached to the inlet manifold behind the collector head or does it attach somewhere different? A diagram would be great. Cheers
@@truck-tek the Prima 4010 has a reciprocal primer fitted behind the pump, this has 2 red hoses that attach to the pump to remove air from the casing, im trying to work out if they attach to the discharge side of the pump or the inlet side of the pump?
@@jarydwilson6706 this is a 3010 with prima primers that run on a electro magnet clutch. they are mounted either side and join to a check valve to the rear of the pump via a hose each side. This valve is then mounted to the low pressure side which sucks the air from the casing. I'll try get a pic if it lets you upload them on here.
if it isnt making vacuum to pull from open water It has a Vax leak somewhere Usually the piston primer seals are split Or it's drawing in air from.somwhere
My pump is not increasing pressure

Thanks for the reply.
Are you able to pump saltwater with those pumps? LP impeller is Aluminium but the rest of the pump is stainless. That should mean corrosion issues.

By primer hose do you mean the suction hose to pull water from a open source or what actually creates the vacuum?
@@truck-tek thanks for replying - i mean the hose coming from the primer that attaches to the priming port. Where is the priming port located?

@@truck-tek Thanks again for your reply, that would be great. Cheers
what is the solution if the suction power of the pump is weak or not strong enough?
