EM Electric Diaphragm Pumps

Its energy efficiency provides a rapid recovery of the investment

The ABEL EM series is available in four different material designs: nodular cast iron (SG), stainless steel (ED) or polypropylene (PP). Using suitable, durable materials for diaphragms, valve seats and balls will give you the best possible combination of materials for your application.

This robust pump technology is especially advantageous for many applications that require low pressure. The ABEL EM is a mechanically driven diaphragm pump that is highly energy efficient, because the drive does not require expensive compressed air. Its compact, special design does not require hydraulic fluid and it can be suitably equipped to provide the performance required by each specific application. The ABEL Electric Diaphragm Pump’s unique design concept and impressively low energy consumption have helped solidify ABEL’s worldwide reputation as the leader in diaphragm pump design.

    Pumping Primary Sludge at a Wastewater Treatment Plant

    This wastewater treatment plant in Colorado, USA has been in operation since the beginning of the 20th century. At the beginning of the 1980s, the plant had to be expanded and ways were sought to transport the primary sludge 18 miles (approx. 29 km) through the city to a neighboring plant for further treatment.

    Process Optimization with EODD Pumps

    Several rotary lobe pumps were replaced with electrically driven ABEL diaphragm pumps for primary sludge pumping. This resulted in longer maintenance intervals and more efficient operation. Subsequently, more rotary lobe pumps were replaced with EM pumps, which significantly improved maintenance.

    Efficient and reliable Process Pumps

    ABEL’s EM series pumps are the most efficient of any positive displacement design. The pumps can be run dry indefinitely. There are no tight places that slurry encounters in its path through the pump. Therefore, the ABEL EM pumps are less subject to abrasive wear than any competing positive displacement design.
