The high energy mixing device will have a minimum speed of 1550 RPM and shall not

be a pump. The mixing chamber shall have a mechanical seal and a 316 stainless

steel shaft and housing.

2.10 Static Mixing

Each unit shall have a secondary mixing unit constructed of clear plastic to allow

viewing of the mixed polymer and water solution. The mixing unit shall contain 316

stainless steel triple action static mixing elements that complete the polymer blending

process.

2.11 Materials

The wetted elements of the unit which contact neat or dilute polymer shall be

constructed of materials that are non-corrosive, such as the following:

§ PVC

§ Acrylic

§ Polyethylene

§ 316 stainless steel

2.20 Controls

Each unit shall be equipped with all necessary controls, pre-wired, to provide the

following minimum functions:

§ Dilution water flow control with rate adjusting valve and flowmeter.

§ Hand-Off-Auto* switch to control power to the solenoid valve, Gatlin mixing unit

and metering pump.

§ Stroke frequency and stroke length adjustments for diaphragm pumps.

§ Local or remote control of pump feed rate. *

§ The remote control shall be in response to a 4 to 20 mA control signal. *

§ Flushing mode switch that shuts off the feed pump and allows water to flush

the system.

* In the hand position, the unit is started and stopped manually, however, the flow

sensor described in paragraph 2.05 remains active and polymer will not feed in

the absence of sufficient dilution water. In the auto position, the unit will run

only when an external contact permits the unit to run. This could be a flow

signal from a waste stream, a level switch signaling the need to refill a storage

tank with dilute polymer to be fed by multiple pumps to multiple points of use or

any other external condition that is desired to cause the polymer blending to

begin or end.
