1. Chemical flow rate calculations are theoretical and are based on zero discharge pressure. As discharge pressure rises, cycle volume and pump speed will decrease.
2. With the Series 1500 Gas Recovery pumps, decrease maximum chemical flowrate by approx. 25%.
3. Reduce Volume/Cycle on Short Stroke models by 50%
4. Pump can exceed maximum recommended discharge pressure. A pressure relief valve, or other appropriate safety equipment, must be used with these pumps.
