8.0 bar plus (120 psi) no leaks --- don’t compromise!

I quite often see our parts incorporated in liquid application systems, but not configured to our specifications.
For starters, all positive displacement pump systems, when using our ‘fluid link’ distribution components, must incorporate a PRV (Pressure Relief Valve).
Our systems have no variables (parts which can induce random application across the bar), but components need protection from pressure ‘spikes’.
I have witnessed pressure spikes exceeding 200 psi when positive drive systems that do not include a PRV are switched on and off! When this happens every component in the distribution system is stressed to the limit.
The image is a pressure test on our check valves (120 psi and no leaks).
Our check valves are individually assembled and torqued to 2.0 Nm. with the use of a mild retention fluid on the threads for the international market.
Australian spec. check valves are now assembled using a more powerful retention fluid to counter expansion when under high pressure loading.
All genuine LQS Pump and Control systems incorporate a 100 psi ‘tamper proof’ PRV to complement our STACKER Distribution Systems.

7 年BEAUTIFUL, Peter. Absolutely!! What a system. How could anyone, writing cheques for fertilizer, not be applying it with this system? Where it is supposed to be,... at the right amount, every single inch of furrow, under pressure,..not dribbling.
