BMG has expanded its fluid handling offering with the introduction of the new EVO 210 series electric double diaphragm pump range, designed to deliver dependable, energy-efficient fluid transfer in demanding industrial applications.

“The new EVO 210 series, which forms part of Ingersoll Rand’s ARO fluid handling products, offers an alternative to conventional air-operated diaphragm pumps. These new electric double diaphragm pumps combine the familiar benefits of diaphragm pump technology with lower energy consumption, quieter operation and simplified maintenance,” says Joe Pinheiro, BMG’s national product manager for pumps.

The EVO series 210 range, engineered for applications requiring reliable fluid transfer, batching and dosing, is suited to sectors including chemical processing, mining, wastewater treatment and general manufacturing. These pumps are designed to handle challenging process conditions while helping operators reduce operating costs and maintenance demands. Unlike traditional air-operated diaphragm pumps that rely on compressed air, the EVO series uses an electric motor to drive a mechanism that moves flexible diaphragms in a controlled reciprocating motion, creating suction by drawing fluid into the pump chamber before discharging it through the outlet valve, delivering smooth and consistent flow. By eliminating the need for compressed air infrastructure, the system improves overall energy efficiency while reducing operational noise.

A key feature of the new range is its focus on operational efficiency and reliability. Compared with air-operated alternatives, the EVO series 210 significantly reduces energy consumption while maintaining robust performance. Secondary leak containment for process fluids enhances operational safety, with optional electronic leak detection available for applications where early fault warning is essential.

Maintenance has also been simplified through a practical design that allows access to both diaphragms from the same side of the unit, an advantage in confined installation environments where service access is often restricted. A durable, straightforward drive mechanism with fewer components improves long-term reliability while reducing service complexity and maintenance costs.

The EVO series 210 is available in both metallic and non-metallic configurations. Metallic variants in aluminium and stainless steel provide durability for demanding mechanical environments, while polypropylene and polyvinylidene difluoride non-metallic options offer enhanced chemical compatibility for aggressive fluid handling applications.

The EVO 210, a 2,5 cm model within the range, is equipped with a 1,5 kW four-pole motor and is suitable for smaller batch and dosing applications. Multiple voltage and frequency units enable compatibility with varying electrical supply requirements, while inverter-duty motor capability allows integration with variable frequency drives where process control flexibility is required. The range meets ISO 12100 standards and carries CE certification. Metallic pumps are also available for hazardous environment applications requiring relevant compliance.

BMG supports this range with a technical advisory service to ensure the selection of the most suitable pump for every application, and also supplies a full range of ARO diaphragm pump parts and accessories for standard repair and maintenance requirements.
