JaecoFram 1 Diaphragm Metering Pumps - Jaeco Fluid Systems, Inc.

(0.8 to 56 GPH)

Specially designed for accurate, completely leak-proof metering of difficult-to-handle liquids.
Separate chambers for hydraulic fluid and gear lubricant make possible the use of the best medium for hydraulic diaphragm pulsing and the best medium for gear lubrication. The results are better pump performance and longer pump life.
Available in both simplex and duplex models. Field convertible from simplex to duplex.
Patented, heavy-duty gear reducer system for superior performance.
Hydraulically actuated diaphragm minimizes diaphragm fatigue.
Built-in hydraulic relief valve protects the pump.
Capacity is manually adjustable while pump is running or idle.
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.
Easy-to-read stroke length adjustment dial.
No plunger seals to leak or replace.
Oil bath gear lubrication eliminates the maintenance required by packing grease or auxiliary oil systems.
Top-mounted lube oil and hydraulic fluid fill ports for easy access.
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 therefore is self-cleaning.
Available with or without motor.
All units come epoxy painted, completely assembled on a base plate and have been fully tested.

Diaphragm: PTFE
Liquid End: 316 Stainless Steel

Spring-loaded single ball check valves.
Double ball check valves with or without spring-loaded balls.
Double diaphragms with diaphragm rupture detection eliminates process fluid contamination or pump housing damage in the event of a diaphragm rupture.
