To improve safety in the handling of hazardous substance, a new pump tube made of chlorinated polyvinyl chloride (CPVC) aims to help reduce the risk of spills and injuries. The pump tube is designed as a vertical immersion pump. With an immersion depth of 39 in., it can be inserted directly into drums and canisters. An electrically or pneumatically operated motor can be attached on top. The motor drives a radial impeller via a shaft, which guides the medium into a conveying line through centrifugal force. This enables the safe conveying of up to 25 gal/min (95 L/min) without any risk of spillage. An optional dispensing nozzle and flowmeter enable targeted dispensing. The pump tube is made of chlorinated polyvinyl chloride (CPVC). This makes it resistant to chemicals and ideal for transporting not only sodium hypochlorite, but also alkalis (including caustic soda and potash lye), precipitating and flocculating agents (including iron or aluminum salts), and cleaning and rinsing chemicals. Additional safety is provided by the fact that the design does not use any seals on parts that come into contact with the medium. This reduces the risk of leaks. While PVDF versions offer similar chemical resistance, the CPVC model is significantly more economical (often 20–30% lower in price based on market comparisons) without compromising performance for suitable media. This makes it an ideal choice for budget-conscious operations that demand durability and safety. — Lutz Pumps, Inc., Norcorss, Ga.
