Unique Design and Construction Means Trouble-Free Operation and Low Maintenance

BODY BLOCK AND LINER SELECTION
A rotor mounted on an eccentric shaft oscillates within the flexible liner, imparting a progressive squeegee action on the fluid trapped in the channel between the liner and the body block. Flanges on the flexible liner are pressed to the side of the body block by concentric grooves on the pedestal assembly and the cover plate. This serves to isolate the fluid to the channel. Pump models are available close-coupled or pedestal-mounted to an electric motor, or air-powered for handling volatile fluids. These pumps are ideally suited for use on a variety of stationary and mobile acid buggies for the transfer of chemicals in laboratory and plant operations as well as for incorporation on OEM equipment.
The wide choice of thermoplastics and elastomers in which these pumps are furnished permits their use over the full pH range and for an endless list of corrosive and abrasive clear and viscous fluids. (See Chemical/Material Resistance Chart)
XB & CC models satisfy laboratory, production and OEM applications
FLEX-I-LINER® pumps are available close-coupled to an electric motor, or pedestal-mounted with electric motor drive or gasoline engine, as well as air powered when required for handling volatile fluids. For metering and dosing, variable speed motors or belt drives may be used. Models may be hand carried, installed on casters, or wheel-mounted on mobile equipment for portability.
Sanitary, sealless, metering pump has flame polished body
With no internal crevices, dead spots, threads, seals, or bearings, this
FLEX-I-LINER® self-priming pump is ideal for sanitary metering of pharmaceuticals, foods, and other contamination-sensitive products. The body block in the unit illustrated is molded of UHMW polyethylene with flame polished interior surfaces, and spin-welded suction and discharge quick-disconnect fittings. The rugged flexible liner is molded of food grade elastomers. Metal never touches fluid.
Air-driven plastic pump handles volatile fluids, gases
For pumping volatile chemicals and gases where safety requirements prohibit the use of electric power, or in remote areas where electric power is not available, FLEX-I-LINER® pumps can be supplied with rotary vane air motors, which develop 2000 rpm on 90 psi (620 kPa). These motors can be furnished in models for clockwise rotation, or reversible operation to change flow direction. Control of the air motor drive offers a convenient means for varying flow rates.
Dosing is automatic, reliable with variable speed pump
Variable speed FLEX-I-LINER®pumps offer automatic dosing capability with dependable accuracy. A sensor immersed in the fluid being treated continuously relays data on pH, conductivity, or other variables, to a controller which adjusts pump motor speed and dosage rate. The design simplicity reduces the cost, maintenance, downtime, and complexity associated with dosing and metering applications.
Drum pump runs dry, self-primes, cuts maintenance
Ideally suited to evacuate drums, the FLEX-I-LINER® pump is self-priming, can run dry for extended periods, and is simple to maintain. It also runs slowly — 1750 versus 5000 rpm for typical drum pumps — and offers greater safety and convenience in a diversity of situations. Compact in size with integral handle, it fits neatly on drum lids without hazardous protrusions, and has sufficient lift characteristics to operate from the floor, skid or stand.
Duplex configuration features high capacity, smooth operation
"Duplex" FLEX-I-LINER® pumps offer 70 percent higher flows than "Simplex" configurations while minimizing vibration at higher pressures. One motor/gearbox drives two opposing eccentric shafts oriented 180? out of phase/rotation, canceling pumping pulsations generated within each fluid cavity. Manifolds provide common suction and discharge connections. Duplex systems are available in the same thermoplastic and elastomeric materials as single-stage units.
