Plastic Diaphragm Pumps

Engineered to meet stringent standards for hygienic design, product quality, and food safety.

The MEMDOS LP motor-driven diaphragm dosing pump is the ideal choice for applications where the pump needs to be integrated into control systems or control loops. A version with an Ethernet-based MODBUS interface is available specifically for integration into sophisticated automation networks, enabling seamless communication and control. Equipped with a robust plunger drive and the option of manual or automatic capacity adjustment, the MEMDOS LP reliably and precisely doses various media such as acids, alkalis, precipitants and flocculants. This flexibility and precision make it a reliable component in various industrial processes. The MEMDOS LP is also available with a double diaphragm system on request, which ensures increased safety and reliability.

Depending on the pump housing, the diaphragm pumps operated by compressed air can be offered in metal or plastic. Air operated diaphragm pumps made of plastic The double diaphragm pumps made of plastic have a pump housing made of polyethylene or PTFE, each also in a conductive version as an ATEX pump for use in hazardous areas. The compressed air diaphragm pumps in solid construction made of polyethylene can be used for abrasive, viscous and shear sensitive media. Air operated diaphragm pumps made of metal The metal pumps have a pump housing made of aluminum, cast iron or stainless steel. All pumps are available with composite membranes made of PTFE, EPDM or NBR. The material of the valves and seals is coordinated according to the choice of membrane.
