No single pump suits every chemical application. The ideal chemical transfer pump depends on factors such as chemical compatibility, viscosity, temperature, flow rate, pressure requirements and whether the installation is fixed or portable.
Global Pumps recommends the following five pump technologies for safe and reliable chemical transfer.
Techniflo magnetic drive pumps are sealless by design, which means there is no leak path and no seal to wear out. This makes them an excellent corrosive chemical transfer pump where aggressive chemicals would quickly damage a conventional shaft seal, or where any leakage presents a safety or environmental risk. The range delivers flows up to 340 m³/hr, pressures to 20.6 bar and handles liquid temperatures up to 120 °C, making it one of the most capable options here for continuous, high-volume transfer of corrosive liquids.
With Verderflex peristaltic pumps, the fluid only ever touches the inside of a hose, never the pump itself. This makes them one of the most forgiving options for highly corrosive or abrasive chemicals, and they run dry without damage, which matters when supply tanks run low. The VF125, the largest model in the range, delivers flows up to 90 m³/hr at pressures to 16 bar and temperatures up to 80 °C, making it well suited to chemical dosing, metering and the transfer of aggressive industrial liquids.
Verderflex tube pumps use a tube rather than a hose, which is the main difference from the peristaltic range above. The Vantage 5000, the top model in this range, runs at up to 396 L/hr with pressures to 7 bar and temperatures up to 40 °C. While this is lower than the hose pump range, it makes these pumps well suited to lighter duty applications involving cleaner fluids, general chemicals and light slurries. In exchange, the setup is simpler and tubing changeover is quick and easy, which makes this range a practical choice where the application doesn't demand the higher flow, pressure or temperature tolerance of a full hose pump.
Verderair air operated double diaphragm (AODD) pumps need no electricity, which makes them a natural fit for outdoor sites, tanker loading, drum decanting and hazardous areas. These portable chemical transfer pumps self-prime and can run dry without damage, providing reliable performance across a wide range of industrial applications. The largest model in the range delivers flows up to 530 L/min, pressures up to 8.6 bar and handles temperatures up to 135 °C, the highest temperature capability of any pump on this page. This makes it an excellent option for transferring hot, hazardous or thermally demanding chemicals.
Techniflo drum pumps are purpose-built for transferring chemicals from drums and IBCs, whether that's emptying a 20 L container or a full 205 L barrel. Available in electric and manual configurations, the range delivers flows up to 200 L/min and handles temperatures up to 120 °C. Global Pumps recommends these portable chemical pumps where flexibility is important, making them ideal for occasional transfer tasks, drum decanting or moving chemicals between multiple containers across a site.
