Hi Ken, thanks for your question. Yes there is; approximately 1 metre of max head is equal to 1.42 PSI. So you can simply multiply the maximum head of the pump by 1.42 to give you the max psi rating of that pump. For example, if a pump has a maximum head of 40 metres, then its max pressure is approx. 57 PSI.
For reference, a typical garden hose dispenses water at about 30-40PSI. Generally speaking, Transfer Pumps will have lower PSI capacity, but can move larger volumes of water, whereas High Pressure Fire Fighting Pumps will have a higher PSI but move lower water volumes on a litres per minute measure.
Hope that helps, thanks - Steve.
