Blue River Technologies liquid make down systems are designed utilizing the Walchem HV
(High Viscosity) series diaphragm pump. These emulsion polymer make down system are available
with water flow rates of 5, 10, or 15 gallons per minute. This system is designed to make down
emulsion polymers at up to 1% concentrations.
A disc style check valve is located in the polymer line at the point of injection. When the
control receives the command to shut down water flow the polymer injection pump is shut down and
water is allowed to continue to flow for a programmed delay period to flush out the mixing head
and lines. A time delay is also used to establish water flow prior to turning on the polymer
The Base and Stand is constructed from 304 Stainless Steel. All pipe and fittings are Schd 80
PVC width to provide the user years of trouble free service. The stand is designed to rest at
floor level but all components of the system are mounted to the stainless steel back plate
allowing the user to wall mount the unit.
The control is PLC based providing the flexibility needed to properly flush out the mixing head
at the end of the fill or inject cycle and also allows the control to monitor water flow and
polymer flow. If water flow falls below a set point the control will shut down the system and
go into a fault condition. If polymer flow is interrupted the PLC will shut down the system and
put the unit into the fault mode.
The enclosure is Nema 4X and includes rugged industrial duty Cutler-Hammer switches and
A relay is provided to allow the user to send a signal to the control room if the system goes
into a fault condition for any reason.
The Blue River Technologies mixing head is specifically designed for mixing emulsion polymers.
The head utilizes low pressure, high kinetic energy mixing nozzles that will thoroughly mix the
most difficult to invert polymers. This head will eliminate angel hair and agglomerations.
The mixing head utilizes a clear PVC mixing chamber allowing visual confirmation of the mixing
process. Many polymers can be mixed and directly injected into the process stream or the
start/stop relays can be used with conductive probes in an aging tank to maintain level between
high and low probes. The control can also be set up to start/stop using a remote set of contacts.
