Duplex II
Industrial Series
Low Pressure (30 to 60 PSI)
High Pressure (70 to 100 PSI)
Description
FLOJET Industrial Duplex II Pumps are designed for a wide range
of applications and are constructed from a selection of materials
suitable for handling a broad range of chemicals. The Duplex II
series of diaphragm pumps are self-priming and can be run dry
without harm. They are intended for intermittent duty cycles but
can be run continuously for short periods of time. The higher the
duty cycle the shorter the expected life of the pump.
Typical pump uses are liquid transfer, spraying, cooling,
circulation, filtration and dispensing.
(115 Volt AC) UL recognition is based on
CAUTION
testing using water
Mounting CAUTION
The FLOJET Duplex II Series pumps are self-priming. Vertical
prime may vary depending on the fluid viscosity, suction tube
size, foot valve and pump configuration. The pump should be
mounted in a dry and adequately ventilated area. If mounted
within an enclosure, provisions to cool the motor may be
necessary.
CAUTION
If mounting the pump in an outdoor environment
the pump should be shielded from water, dust, sunlight and
wash down spray.
Do not assume chemical compatibility. If the fluid is improperly
matched to the pumps Elastomers, the pump may fail to prime,
have low pressures or the pressure switch may not shut off.
Horizontal Vertical NOTE: Do Not Submerge
Plumbing
Use flexible hose of the correct pressure rating that is compatible
with the fluid to be pumped. Tubing should be a minimum of
3/8" (9.5 mm) ID and at least 20 inches (508 mm) in length to
avoid excess stress on the pump ports. Do not crimp or kink
the tubing. The pump head maybe rotated in 90° increments to
simplify plumbing.
CAUTION
Do not use of metal fittings, standard plastic male
and female threaded fittings can be acquired at commercial
plumbing supply stores. FLOJET also distributes plastic barb
fittings through our distributors (form no. F100-001).
CAUTION
The use of check valves in the plumbing system
could interfere with the priming ability of the pump. If a check
valve is installed in the plumbing it must have a cracking
pressure of no more than 2 PSI (.14 bar).
CAUTION
Use of a minimum 40-mesh strainer or filter in
the pump inlet line will prevent foreign debris from entering the
system. Failures due to foreign debris entering the pump will not
be covered under the limited warranty.
Note: Inlet pressure must not exceed 30-PSI (2.1 bar) maximum.
Sistemas eléctricos
ADVERTENCIA
¡Riesgo de electrocución!
Para cablear las bombas de accionamiento eléctrico, deben seguirse
todos los códigos eléctricos y de seguridad.
Asegúrese de que el suministro eléctrico coincida con el voltaje de la
bomba. Asegúrese de desconectar todos los suministros de energía
antes de la instalación.
La bomba debe cablearse a un circuito individual (dedicado),
controlado con un interruptor bipolar certificado por UL/C-UL
especificado como mínimo para el amperaje del fusible indicado en
la placa de datos del motor de la bomba.

Operación
Para arrancar y cebar la bomba, se debe abrir la línea de descarga
para permitir que escape el aire atrapado evitando así la posibilidad
de formación de bolsillos de aire. El interruptor de presión corta
automáticamente la bomba cuando se cierra la válvula de descarga
y la presión aumenta al punto de ajuste de corte del interruptor.
El interruptor rearranca la bomba cuando se abre una válvula y la
presión de la tubería de descarga desciende al punto de ajuste de
encendido del mismo.
