Jaeco Hi-Flo™ Packed Plunger Metering Pumps
(20 to 682 GPH; up to 7200 PSI)
Features/Benefits
- Heavy duty positive displacement for continuous, accurate metering at higher flow rates and/or pressures.
- Positive displacement supplies a simple and virtually maintenance-free approach to accurate chemical feed.
- Available in both simplex and duplex models.
- Capacity is manually adjustable, but only while pump is idle, 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.
- 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.
- Integral lantern ring for packing lubricant may be used for internal purging when handling crystallized, corrosive or other hazardous liquids.
- Packing adjustment screwed gland nut ensures even take-up and fewer packing problems.
- Models 324, 332 and 340 have a clamped column, suction and discharge check valve assembly that can be easily cleaned, inspected or replaced without breaking pipe connections.
- Available with motor or as bare pump.
- All units come epoxy painted, completely assembled on a base plate and have been fully tested.
