High-Pressure Metering Machine Suits polyurethane manufacturers

Latrobe, PA - Polyurethane Process Industries, LLC, (PPI) has introduced a new high-output, high-pressure metering machine that provides better processing control to North American polyurethane manufacturers on a budget.
The new compact ECOPlus metering machines from OMS Group deliver outputs up to 475 lbs./minute and offer more standard features than other economically priced models, including:
- Variable speed motors controlled by an Allen-Bradley MicroLogix series PLC, which allows output variations without manual intervention.
- Fixed-displacement axial piston pumps with double seals for low maintenance.
- Jacketed, pressurized tanks with low-speed agitators for improved temperature control.
- L-style mix head with chemical/hydraulic separation and adjustable cleanout piston stroke for optimum mixing.
"With the ECOPlus, you get a lot of performance for a relatively low price," said Mark Clark, general manager of PPI, which is the exclusive dealer of OMS equipment in the United States.
"The machines are suitable for virtually any polyurethane application. And there are a lot of features on a standard ECOPlus that are not available, or available only as pricey options, on other basic metering machines," Clark said.
OMS designed the ECOPlus for flexibility, reliability, easy operation and low maintenance.
The ECOPlus frame is compact, with components mounted for easy access. The control system is completely self-diagnostic, continuously checking that all variables are within the correct pre-set operating ranges. If a variable falls outside its range, the ECOPlus will signal an alarm and display a clear text message indicating the cause of the problem and what the operator should do to maintain safe working conditions. The control also keeps track of items that require routine maintenance.
The operator can carry out nearly all operations without leaving the pour station. All operating parameters and machine variables, including outputs, are set and displayed on a monochromatic touchscreen panel mounted with the mix head at the end of the boom. If the ECOPlus is configured with two mix heads, the touchscreen is placed at the main operating panel.
The Rotary Power metering pumps and a control system based on Allen-Bradley technology and components ensures worldwide availability of parts and service. Because the pump output is adjusted via an inverter and the PLC, the pumps have fewer seals and parts to maintain.
"There are a number of accessories available to make operation and maintenance even easier," Clark said. "We can add fill pumps, closed-loop flow control, magnetic couplings on the metering pumps or any of dozens of other available options to make the ECOPlus fit a specific application or workflow."
