JaecoPak Metering Pumps - Jaeco Fluid Systems, Inc.

(0.38 to 150 GPH)

Streamlined design and rugged construction provide a low-cost, uninterrupted, trouble-free service for the continuous accurate metering of chemicals and solutions.
Positive displacement supplies a simple and virtually maintenance-free approach to accurate chemical feed.
Available in both simplex and duplex models. Field convertible from simplex to duplex.
Capacity is manually adjustable, but only while pump is stopped, as a safety precaution and for tamper resistance.
Capacity is easily automated using variable-speed drive.
Stroke length is adjustable for a turn-down ratio of 10:1.
Accuracy of ± .5% at steady state.
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 possible over pressuring 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).
Available with or without motor.
All units come epoxy painted, completely assembled on a base plate and have been fully tested.

Liquid End: 316 Stainless Steel, Alloy 20
Seals: Neoprene, PTFE, Viton®

Spring-loaded single ball check valves.
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.
