How to Calculate Pressure Loss in a Spray Hose for Correct Pump Sizing
When sizing your airless spray pump, it’s crucial to calculate the pressure loss in your spray hose to ensure optimal performance. Here’s how you can do it:
[pumpsizecalc minimum_pressure=”Minimum fluid pressure required at the pump:” notes=”Note: Recommended cycle rate for a continuous duty pump circulation system (PCS) is 12 cpm. Recommended cycle rate for a intermittent duty, dead headed spray system is 20 cpm.”][/pumpsizecalc]
How to Properly Size Your Pump:
To correctly size a pump for your application, it’s essential to determine the minimum pressure required at the pump to overcome the pressure loss in the fluid line from the pump to the dispense valve. The above information helps you calculate a simple (no elevation) pressure loss from the pump to the dispense valve.
