An Extensive Product Range of AODD Pumps

Almatec Maschinenbau is the actual inventor of plastic solid-body AODD pumps and offers an extensive product range. In the handling and transfer of dangerous chemicals, the company recommends its E-Series AODD Pumps. E-Series pumps offer a long list of features and benefits for handlers of dangerous chemicals.

• Solid-Body Construction: E-Series pumps are CNC-machined from solid blocks of polyethylene (PE) or polytetrafluoroethylene (PTFE). The result is a pump that is not prone to the creation of leak paths while being able to operate with the most dangerous chemicals in the harshest pumping environments.

• Diaphragm and Containment Ring: The E-Series features a unique stainless-steel containment ring and ring-tightening structure that helps create consistent high-torque compression that pulls the components tightly together and compresses the diaphragm in such a way that a leak-free seal is achieved.

• Perswing P Air Control System: The Perswing P is a lube-free valve with only two moving parts that allows the E-Series pump to achieve superior flow-rate efficiency and air consumption, which helps lower the overall cost of operation.

• Material Compatibility: The E-Series pump’s housing can be constructed of PE, PTFE, PE conductive or PTFE conductive, which allows it to be used with a wide range of chemical formulations. Additional versatility in regards to material compatibility is realized through the availability of EPDM, PTFE/EPDM and NBR diaphragms; EPDM, PTFE, NBR and stainless-steel ball valves; and PTFE cylinder valves.

• Intrinsic Safety: E-Series pumps that are constructed of PE/PTFE conductive plastics are intrinsically safe and meet the requirements of the Atex 94/9/EG directive. This means they can be safely used in explosive atmospheres or when pumping flammable liquids.

Almatec is now offering its E-Series AODD pumps, which can be used a s a direct replacement for its previous A-Series line, in seven sizes: the 6.4-mm (1/4") E08 with flow rate to 15 L/min (4 gpm); the 9.5-mm (3/8") E10 with flow rate to 23 L/min (6 gpm); the 12.7-mm (1/2") E15 with flow rate to 55 L/min (15 gpm); the 25.4-mm (1") E25 with flow rate to 130 L/min (35 gpm); the 38.1-mm (1-1/2") E40 with flow rate to 330 L/min (88 gpm); the 50.8-mm (2") E50 with flow rate to 600 L/min (160 gpm); and the 76.2-mm (3") E80 with flow rate to 800 L/min (210 gpm).

Conclusion

You may not want to see how they are made, but we can’t live without laws. The same is true for thousands of consumer or industrial products that are manufactured on a daily basis. While we may not want to know what types of dangerous chemicals, solvents, caustics or acids are being used to make paints, detergents, paper and fertilizer, we also know that we can’t live without them and that we don’t want them to be released to the atmosphere or environment.

That’s why full containment of these hazardous, flammable or explosive substances is a front-of-mind concern for the plant operators who handle them. Those concerns can be alleviated, however, through the use of pumping equipment that has been designed to achieve full containment of dangerous chemicals. While other pump technologies can claim to do this, only plastic solid-body AODD pumps can turn those claims into reality.
