Triplex Metering Pump with “Pulse-Free” Linear Flow

  • Multiple-diaphragm design provides virtually pulse-free, linear flow without the need for expensive pulsation dampeners.
  • Designed for low flow rates at high pressures.
  • Can run dry indefinitely.
  • Will operate without damage to the pump in the event of a blocked suction line.
  • Handles a variety of processing fluids.
  • Electronic flow control increases accuracy and reliability.
  • Available with manual flow adjustment that can be used in hazardous areas.
  • The integral relief valve protects the pump from over pressurization on the discharge side.
  • One pump covers a wide range of flows and pressures-reducing inventory requirements with fast, simple field conversion.
  • Duplexing option doubles capacity and equipment savings.
  • Hydraulically-actuated, balanced diaphragms provide superior performance across the entire pressure range.
  • Seal-less design means no seals, cups, or packing to leak or replace.
  • The replenishment valve system in every piston ensures optimum actuating oil on every stroke for continuous accuracy and protects the pump from damage in the event of a blocked suction line.
  • Rugged construction.
  • Smaller footprint saves valuable space.
