Series 500 Original in PVC

Neptune Series 500 Original Metering Pumps

Series 500 Original has the same features as the Series 500 Standard line, except these models can be duplexed. Any duplex pump combination can be created using any of these models, so long as both models have the same stroking speed. (Add 15 lbs. to shipping weight for duplex models.)

Features:

  • Standard Motor: 1/3HP-1ph-115VAC-60c-TEFC
    Totally Enclosed Fan-Cooled with built-in automatic thermal overload protection
  • Ten turn micrometer dial calibrated in 1% increments.
  • Bright color contrasted dial protected from corrosion by clear PVC covering.
  • Stroke mechanism moves only when adjustment is made, eliminating wear.
  • Piston is powered through complete stroke length at all capacity adjustments eliminating stress, wear and shock of lost motion designs.

Notes:
Change the letter "S" in the model number to the letter "D" to specify a duplex pump with identical heads.
547 models are furnished with an integral 1/2HP-1ph-115VAC-TEFC motor as standard.
Neptune recommends that 1/2 HP high pressure models be used only in flooded suction applications.
Shipping weights are for standard motors only. For flange mounted motors, add 20 lbs.
