Jesco pumps are used to portion the exact amount of any particular liquid. They are available in three different types. Magnetically-operated diaphragm dosing pumps are good for small amounts. Chlorine swimming pools, for example. Motor driven diaphragm dosing pumps and three phase pumps are good for a consistent flow. Mixing chemicals with water or adding it to concrete, for example. Piston dosing pumps are for high pressure requirements. These are used for dosing fluids with highly varied viscosities, most of which are chemically aggressive and toxic, and some of which are actually abrasive or emit gases.
Flux barrel and canister pumps are used to pump from barrels, tanks and other containers. They consist of motor and attached pumps. The pumps can be made of various materials based on the type of liquid they process. For example, PP plastic to pump corrosive liquids, rust-free steel for pumping solutions of PVDF plastic to pump strong chlorine. Specific pumps are available to deliver tough liquids like syrup or paint. The motors are of various designs such as air-driven pumps to ones that are driven by spark arrestors for flammable liquids.
Masterflex hose pumps are made for maximum hygiene in fields such as pharmaceutical or food distillations. The liquid only touches the hose and does not come in contact with metals. Its tight seals make it leak-free and safe from contamination. The pumps can perform suction of 8 meters and lift up about 27 meters. They are available with a control system for accurate doses of liquid. The hoses have various designs based on the type of liquid required for pumping.
