Chemical Metering Pump Feed Rate Calculator

Chemical Metering Pump Feed Rate Calculator

Formula:

GPH = (GPM x .006 x PPM) /  % Concentration x S.G.

Where,

• GPM = flow to be treated.
• .006 = Constant.
• PPM = Dosage required.
• % Concentration = Concentration of chemical in pumped solution
• Use full number (15% solution is [15] in formula not (.15)).
• S.G. = Specific gravity at pumped solution. 

---

GPM :	m3/h
PPM Dosage :	mg/l
Concentration of Chemical:	%
Specific Gravity at Pumped Solution:
Gallons Per Hour (GPH)

Example:

2% solution is required for pumping a 55 gallon feed tank is in use and 12% chemical is available.

 55 x 2
 -------- = 9.17 gal. chemical to 45.83 gal. water in tank
    12
