Employing a 4 to 20 mA or pulse
input, OMEGA’s PHP-300
programmable, solenoid-driven
diaphragm liquid metering pumps
can be operated manually or
automatically. The PHP-400 and
PHP-500 Series are diaphragm
liquid metering pumps designed for
manual operation. The stroke length
for all pumps is manually adjustable
from 10 to 100% and the stroking
rate from 12 to 125 strokes per
minute. Head and filling material
options include glass-filled
polypropylene, polyvinylidene
fluoride (PVDF), and AISI-316 SS.
The diaphragm is made of
PTFE-faced CSPE. The guided
check valves provide precise
seating along with excellent priming
and suction lift characteristics. The
PHP-310 Series incorporates all the
features of the PHP-300 as well as
a 4 to 20 mA input signal, while the
PHP-320 accepts a pulse input
signal. Every unit comes with an
inlet strainer/foot valve and an
injection valve. In addition, “G” and
“K” models are equipped with
1.2 m (4') of PVC suction tubing,
2.4 m (8') of PE discharge tubing,
and bleed valve assembly.
