First HP Sitrup pump

[elitesniper]

Finally got around to making a pump
Machined the piston head and shaft stablizer from nylon
check valve is a marble sealing a against a washer/rubber washer and a spring
tube is 3/4 copper m
sand made from wood painted silver
handle 1'' copper

Nicely made, you failed to mention what pressures you're getting though

Nice indeed. Does it work properly, does everything seal?
Beware of the checkvalve, if it leaks your pump will become a ram.

Now go exercise!

me to

but you have a big dead volume between the O ring and the check valve so you will get to the point you compress the air in the cylinder and cant pass he cant pass the check valve
