DESCRIPTION:
The series 4300 chemical injectors are electric motor
driven, positive displacement pumps utilizing an integral
worm gear drive available in three different standard
ratios and 6 plunger sizes to provide a wide
selection of volumes and pressures .063 GPD up to
325 GPD per head, against pressures from 150 to
5000 psig. An optional 10 to 1 gear reducer, mounted
externally, is available for extra low pumping rates
from 1-1/4 gallons per day down to 1/2 pint per day.
Pumps are standard with a micrometer type stroke
adjustment that puts an end to the tedious work of
stopping and starting the pump while trying to set the
proper flow rate. A 0-100% change in capacity is possible
while the pump is running. Each complete turn of
the knob results in a 10% change in stroke setting.
Repeatable accuracy is 1% of set point. Up to eight
heads driven by a common motor are possible, and
each head can be independently adjusted.
The standard, virtually trouble free packed plunger
injector heads have built-in priming valves and a dripring
type barrier that will prevent chemicals from being
conducted along the plunger and into the gear box.
Standard pumps can be furnished with high strength
ductile iron or all stainless steel liquid ends to handle a
wide variety of chemicals used in oil and gas production
facilities, pipelines, process plants and other
applications where a rugged, easy to maintain
proportioning pump is required.
FEATURES:
• Integral gear drive and crosshead mechanism in
heavy cast iron housing with an oil level sight gauge.
• Output gear of high strength alloy iron is supported
in a sturdy special bearing arrangement for
maximum rigidity to assure extremely long fife.
• A special drip-ring feature on the plunger prevents
chemical from being conducted into the gear box
and contaminating the lubricant.
• Oil level gauge on gear box.
• A full gasket under the gear box cover provides a
positive barrier against moisture, dirt, and corrosive
vapors.
• Choice of interchangeable liquid ends
• Multiplex models with up to 8 heads driven by
a common motor are available.
• Stainless steel tanks
• Flow rate is adjustable while the pump is running.
