The JAECO PAK is a packed plunger metering pump with a streamlined design and rugged construction that provides low-cost, uninterrupted, trouble-free service for the continuous accurate metering of chemicals and solutions. The positive displacement supplies a simple and virtually maintenance-free approach to accurate chemical feed. This metering pump is available in both simplex and duplex models and field-convertible from simplex to duplex. The capacity is manually adjustable, but only while pump is stopped, as a safety precaution and for tamper resistance. The capacity is easily automated using a variable-speed drive.

JAECO PAK FEATURES & BENEFITS

  • Provides a simple and virtually maintenance-free approach to accurate chemical feed.
  • Stroke rate easily automated using variable-speed drive.
  • Capacity is manually adjustable, but only while pump is stopped, as a safety precaution and for tamper resistance.
  • Stroke length is adjustable for a turn-down ratio of 10:1.
  • Available with or without motor.
  • Oil bath gear lubrication eliminates the maintenance required by auxiliary oil systems.
  • Single ball check valve, standard on both suction and discharge side of the pump, provides accurate metering and fast response. Valve ball turns with fluid flow, constantly presenting a new face to the seat, and is therefore self-cleaning.
  • Because it is a true positive displacement pump, a safety relief valve on all closed loop systems is required to prevent the possible overpressuring of the discharge line.
  • Packing adjustment screwed gland nut ensures even take-up and fewer packing problems.
  • Integral lantern ring for packing lubricant may be used for internal purging when handling crystallized, corrosive or other hazardous liquids.
  • Pump arms can be reversed to reduce footprint.
  • Duplex pumps can have different size pistons.
  • Pistons are normally 180° out of phase, but can be synchronized so that two fluids are pumped simultaneously (i.e. resin and hardener in a fiberglass plant).
  • Accuracy of ± .5% at steady state.
  • All units come epoxy painted, completely assembled on a base plate and have been fully tested

PUMP OPTIONS

  • Double ball check valves with or without spring-loaded balls.
  • Purge-port plugs, available in cylinder end, can be used to bleed air during and after start-up and to solvent-purge the liquid end. They also provide easy access to the cylinder without breaking pipe connections.
  • 440 hardened plunger for abrasive fluids.

MOTOR OPTIONS

  • Electric
  • Gas
  • Air
  • Belt-driven
