A new weatherable solar-powered chemical-dosing system from Vanton Pump and Equipment Corp. features a nonmetallic, peristaltic pump for corrosion-free transfer of caustic and acidic treatment chemicals from an integral thermoplastic storage tank to water and wastewater containment facilities in remote locations.

The pump, Flex-I-Liner model 12, utilizes a rotor mounted on an eccentric shaft to push fluid trapped between a flexible elastomer liner and a solid plastic body block.  The self-priming design has no seals to leak or valves to clog and can run dry without damage.

The rigid body block features a solid polypropylene, UHMW polyethylene or PTFE mold, and the flexible liner of natural rubber, neoprene, Hypalon, Viton or Nordel eliminates corrosion associated with pumps constructed of stainless steel and high alloys and wicking and delamination associated with fiberglass and plastic-lined metals, according to the company.

The system is suitable for flows to 2 gpm (7.6 lpm) and pressures to 25 psig (1.72 bar) at temperatures to 185°F (85°C). The pump is designed to meter a fixed volume of liquid over user-programmed time intervals. A throttling valve on the suction line to the pump allows flow rate adjustment
