ALPHA Chemical Metering Systems

seepex’s new series of standard ALPHA chemical metering systems are designed for simple plug-and-play installations.

seepex’s new series of standard ALPHA chemical metering systems are designed for simple plug-and-play installations. Installation is as straightforward as connecting three pipes and plugging into a 115 Vac power source. The systems come in five standard skid configurations: simplex options (one pump, wall or floor mounted), duplex options (two pumps, wall or floor mounted), and triplex option (three pumps, floor mounted). 

Included are NSF/ANSI Standard 61 certified progressive cavity metering pumps which offer several advantages for chemical metering due to the principle of the pumping elements. A metal rotor rotates inside a rubber stator, forming two cavities at the suction end of the stator. As one cavity closes, the other opens forming progressing cavities from one end of the stator to the other. The compression fit between the rotor and stator prevents siphoning and back flow. The pumps are self-priming, pulsation-free and will not vapor lock. No pulsation dampeners, back pressure valves, or check valves are needed.

ALPHA systems handle pressure ratings up to 175 psig and flow rate capabilities from 0.1 GPH up to 70 GPH. Turndown capabilities are 600:1. Regardless of the chemical source tank location, installation remains flexible due to suction lift capability of up to 35 feet. Complete skid assembly includes a mounted unit with pump(s) and gearmotor(s), control panel with controls for flow regulation, calibration column, relief valve, instrumentation and piping. Systems offer local or remote operation with H-O-A switch on NEMA 4X Control Panel with VFD as well as complete protection from overpressure. Control inputs/outputs also include clear power and pump running indication lights, flow command, running speed control, flow rate indication and fault alarms. 

The ALPHA systems are for use in a variety chemical metering applications. Accurate, non-pulsating, and repeatable flow capability results in tighter control and chemical consumption reduction. All skid components are chemical resistant and will hold up in harsh environments. The systems safely deliver thin to highly viscous liquids and withstand corrosive and solid laden chemicals.
