    Edwards Model 150-348 Pump Do not order parts using this manual if the model number on the pump is not 150-348 or the serial number is not ________________. Using parts ordered from the wrong manual could result in pump failure or personal injury. Cautions Do not hammer on pump endcase.

  • Page 7: General

    General Introduction The Edwards Model 150, Model 160 and Model 300 pumps (Figure 1-1) are standard-duty high-speed gear-driven positive-displacement rotary pumps with gear-type rotors. The pumps are self-priming. Edwards rotary pumps are available in many configurations. While they may look alike, there may be significant differences from one pump to another. Differences include construction material, sealing method, rotor type, etc Figure 1-1.
