Replacement water 160psi pump for the HFS2/3/4 system. (without fittings and fixing hardware). The pump pressure can be adjusted to in excess of 280psi with a 1/16" Allen key on the pump head (clockwise).
There are two good reasons why one should not increase the pressure unnecessarily.
The motor used is a permanent magnet type, semi-sealed without cooling channel for air. Winding is the on the rotating spindle so there is no chance of cooling by conduction. Having a large heat sink on the back of the pump will do nothing other than delay the onset of the thermal cut out.
Please contact us if you are using the pump for other application other than for the aquamist systems.
