Figure 3-33: Pressure & Capacity Chart
The SL20 can be tuned to operate in virtually any area of the operating zone;
however, pulsation may become more pronounced in flow rates less than 1 GPM
(3.8 LPM) due to the very low stroke rate. Check set up instructions for optimal
tuning.
NOTE: Test information is based on specific conditions using DI water and
limited sampling. Use for general reference only.
3.3 PERFORMANCE CHARTS – BOOSTER PUMPING
Pumping capacity is a function of air supply pressure and volume, suction head,
suction line restrictions, discharge head, discharge line restriction, and fluid
specific gravity and viscosity.
