Differential Pressure Switch Location of Differential Pressure Switch The high pressure port connects to the inlet manifold between the solenoid valve and the rotameter/rate-adjusting valve. The low pressure port connects to the discharge side of the rotameter. Function of Differential Pressure Switch The differential pressure switch ensures sufficient water flow is present before the polymer pump is energized.

Differential Pressure Switch Adjusting the Differential Pressure Switch Adjust the PolyBlend differential pressure switch only if pressure and flow to the system are adequate. The adjustment logic is the opposite of what you might expect. The PolyBlend differential pressure switches have a red light (on the left side) that lights up whenever source water flow is too low and the polymer pump is disabled.
In the internal mode, output is 0-100 strokes-per- remotely located, using standard cable/connector hour (sph) or 0-100 strokes-per-minute (spm). A sets available from Siemens. touch of the pressure-sensitive keys varies the The REM-1E Digital Display Pump Controller Offers: •...

PRESSURE CONTROL (B and C series only) A capped potentiometer is located on the face plate of the diaphragm pump. This potentiometer is for pressure control or power to the pump solenoid. Since the PolyBlend unit is equipped with a 20 PSI backpressure/check valve, the potentiometer should be set for full power or full clockwise.
