Available In Polypropylene, PTFE or Stainless Steel Liquid Ends
商品説明
The PHP-200B series has been discontinued. Please see the PHP300/400/500 Series as a possible alternative or contact our Flow Engineering department.
The PHP-200B Series is a diaphragm-type, solenoid driven
microprocessor based metering pump with
maximum capacities to 4.5 gph and maximum back
pressures to 253 psig. The housing is constructed of
fiberglass-reinforced PPE plastic, with a NEMA 4X
(IP65) 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 noise suppressing
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 incorporates
all the features of the PHP-200B
and also accepts a current input
signal. This allows the stroking rate
to be controlled by standard process
signals.
SPECIFICATIONS Maximum Stroke Length: 1.25 mm (0.05") Materials of Construction: Housing: Fiberglass-reinforced PPE Diaphragm: PTFE-faced EPDM with plastic core Liquid-End Options: Polypropylene (P), PTFE (T), 316 SS (S) Seal: FKM for P models, PTFE for T and S models Enclosure Rating: NEMA 4X (IP66) Power Supply: 100 to 230 Vac, 1 phase, 50/60 Hz ±10% Repeatability of Metering: ±2% under constant conditions and at minimum 30% stroke length Ambient Temperature Range: -10 to 45°C (14 to 113°F) Max Fluid Operating Temperature: 50°C (122°F) Power Cord: 2 m (6')
注: Each unit is supplied with foot and injection valves, 1.8 m (6') of contact cable for pulse input, and level connector. Polypropylene models are supplied with a 3 m (10') or 1.5 m (5') length polyethylene tubing. † Capacities and suction lifts are for water-like fluids. Higher specific gravity fluids reduce suction lift, while higher viscosity fluids reduce capacity. * “-S” pumps have 1/4" FNPT connections.
