To assist in selection of the correct spray coating pump use either the online or download the Pressure Loss Calculator provided by BlastOne. Steps when using the calculator Step 1: Consult the paint manufacturer's technical data sheet supplied with the coating product. Request the document from the manufacturer if one was not supplied. Step 2: Using the data sheet to find the recommended spraying pressure and also the coating pot life values. Step 3: Decide how many guns you will be running for use in the caluclation. Step 4: Decide how many lengths of hose you will be using. Step 5: Decide number of swivels. Step 6: Decide number of fittings. Step 7: Calculate vertical rise from pump to gun. Step 8: Add pressure loss to paint manufacturer’s recommended spraying pressure to ensure preferred pump has sufficient maximum pressure. Step 9: Decide on power source. Step 10: Determine litres per minute flow rate required. Step 11: Cross reference above data with pump selection guide. Note: Some high viscosity coatings may require heating and/or a ram pump to assist with maintaining a consistent flow.
