Download JAECO-PAK Info Sheet (PDF)

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 the 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.
