2.02 Frame

Each polymer unit shall have a 304 stainless steel open frame that will house and

support all components.

All components in contact with polymer or water shall be of stainless steel, brass or

inert plastic.

2.03 Pump

The pumps shall be an electronic solenoid-driven diaphragm type that have a manual

stroke length adjusting knob and electronic push button control of the strokes per

minute or hour.

Diaphragm pump shall be capable of receiving an external 4-20 mA pacing signal

from a remote monitoring devices (supplied by others) to automatically adjust the

neat polymer feed rate.

Diaphragm pump shall be capable of pumping liquid polymers with an apparent

viscosity of 50,000 cps. Pump shall have a water proof microprocessor type control

panel with a LCD digital display of strokes per minute. Stroke rate shall be 0 — 100

strokes per minute. (Units used to prepare dilute solutions to be stored in a central

tank for distribution to multiple points by other pumps, shall be manually controlled by

the on/off sequence of high and low level switches; the 4-20 mA pacing signal is not

required.)

Pump output shall be: _____ gph minimum. _____ gph maximum. A wye strainer

shall be supplied installed in the suction line for the pump.

2.04 Rotameters

Each unit shall have an integral rotameter type flow indicator to meter and control the

dilution water flow rate. The rotameter shall have a guided float type with acrylic

metering tube scaled in 0 to ____gpm and with a 316 stainless steel and brass

control valve. If more than 1200 gph of dilution water is required, a secondary flow

indicator shall provide an additional 0 – 1800 gph. The secondary dilution water flow

shall combine with the primary flow circuit and pass through a second static mixer

prior to exiting the unit.
