Operation
The SRX LP is installed to the desired drawdown level. It requires only three lines: air supply, air exhaust and fluid discharge. Compressed air is supplied to the pump (generally 0.5 psi per foot of depth is sufficient). As the liquid enters the bottom of the pump through the inlet screen, the internal float moves to the upper (or “ON”) position. At that end point, the float opens the air valve. Air enters the pump, closes the bottom inlet check valve, and pushes the fluid (in the pump chamber) through the center discharge tube and all the way to the surface. As the fluid is expelled from the vessel, the float returns to the lower limit (or “OFF” position) at which point it closes the air inlet valve and opens the air exhaust valve. As the pump fills under the fluid’s own static pressure, air is vented through the exhaust port and the cycle is automatically repeated based on the well recharge rate.
