PHP-202B-P with included
foot and injection valves shown
smaller than actual size.
The PHP-200B Series consists of diaphragm-type,
solenoid-driven, microprocessor-based metering
pumps with maximum capacities to 4.5 GPH and
maximum backpressures to 253 psig. The housing is
constructed of fiberglass-reinforced PPE plastic, with
a NEMA 4X (IP66) enclosure rating to protect against
corrosion, dust, and water. A removable hood covers
the faceplate. The drive unit houses a short-stroke
solenoid with a maximum stroke length of
1.25 mm (0.05"). It is equipped with a noisesuppressing mechanism for quiet operation and has
only one moving part, the armature. The diaphragm
is constructed of fabric-reinforced EPDM elastomer
with a plastic core and PTFE facing. It is chemically
resistant against virtually all process fluids and can
be used over a wide temperature range. Suction and
discharge ports are equipped with double-ball check
valves for maximum repeatability. Feed rate is
determined by stroke length and stroke rate. Stroke
length is manually adjustable from 1 to 100% in
increments of 1% via the stroke length knob. Two
control modes are available for the PHP-200B Series:
manual or analog control.
The PHP-210B Series has all the features of the
PHP-200B Series, as well as current input. This
allows the stroking rate to be controlled by standard
process signals.

Capacities and suction lifts are for waterlike fluids. Higher-specific-gravity fluids reduce suction lift, while higher-viscosity fluids reduce capacity.
