Packed Plunger Metering Pumps
Packed Plunger Metering Pumps
The JaecoPak™ 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.
Materials of Construction:
Liquid End: 316 Stainless Steel, Alloy 20
Seals: Neoprene, PTFE, Viton®
Product & Technology News
- 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.
