P300 Installation Location Important Precautions Locate the pump as close to the supply source as possible. Adequate Fluid Supply. To avoid cavitation and Install the pump system in a lighted clean space where it will be premature pump failure, be sure that the pump will have easy to inspect and maintain. an adequate fluid supply and that the inlet line will not be obstructed. See Inlet Piping. Motor and Controller Positive Displacement. This is a positive-displacement The P Series pump shaft can rotate in either direction, pump. To avoid severe system damage if the discharge line therefore direction of motor shaft rotation is not critical.
P300 Installation (Cont’d) Safety Precautions Recommendations: • Keep inlet lines less than 3 ft. (1 m) long General remarks • Use at least 5/8” (16 mm) I.D. inlet hose • Minimize fittings (elbows, valves, tees, etc.) These safety / installation instructions contain fundamental information and precautionary notes and must be kept available Support the pump and piping independently. to all associated with the operation of the pump. Please read them thoroughly prior to installation, electrical connection and Inlet Piping (Pressure Feed) commissioning of the unit. It is imperative that all other operating instructions relating to the components of individual units are Provide for permanent or temporary installation of a pressure followed.
P300 Installation (Cont’d) Initial Start-Up Procedure Calibration Before you start the pump, be sure that: Note: Each metering pump or pump system must be calibrated to determine the pump speed required for the desired flow rate. 1. All shut-off valves are open, and pump has adequate supply of fluid. Accurate calibration depends on pump discharge pressure and system conditions. When calibrating the pump or system, it is...
