Chemical Metering / Dosing Pumps pumps are essential components in any water treatment system, whether it’s for drinking water, public wastewater, or industrial effluent. There are many different types of pump technologies, although the two most common types for chemical dosing are peristaltic and diaphragm pumps. This article can help you determine which is best suited to your application.
CHEM-FEED® Aluminum Duplex Skid System
The prefabricated design allows for easy installation, simply drop the Skid System in place and make your connections.
CHEM-FEED® Engineered Skid Systems were designed and engineered using solid modeling tools for superior piping installation and easy component maintenance.
- Efficient, Small footprint Design
- The prefabricated 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.
- Corrosion Resistant – CHEM-FEED® skid system frame constructed of chemically resistant polyester powder coated 6061 T6 aluminum. Welded joint construction
- Mounting Pads – Stainless Steel mounting pads to secure CHEM-FEED® System to a solid surface. Designed for floor mount or wall mount
- Pressure Relief Valve x1 – Protects the system from over-pressurization, 5-100 psi setting range, 150 psi maximum system pressure.
- Check Valve x1 – Protects the user from back-flow during pump maintenance.
