Dual Engineered Skid Systems for ProSeries Metering Pumps.
Efficient, Small footprint Design. The pre-fabricated design allows for easy installation, simply drop the Skid System in place and make your connections. Each system is rigorously factory tested. Includes pressure switch option. Easy access to wiring components from the rear of the system.
Joints use Weld-On 724 solvent cement which is chemically resistant to Sodium Hypochlorite and other chemicals.
Dual side inlets enable connection of multiple skids to the same inlet.
The Dual Skid is capable of simultaneous chemical injection of different or like chemical; or one pump can be used as a back-up pump sitting in standby.
Available with the factory options, Custom modifications are not possible.
Optional Flow Verification Sensor for monitoring system: Chemical injection failure stops pump, and triggers an alarm relay to start a back-up pump
