BMG’s new EVO series™ electric diaphragm pumps – which form part of Ingersoll Rand’s ARO fluid handling products – are designed to enhance energy efficiency and improve fluid handling productivity in many industries, including the chemical and petrochemical sectors.
EVO metallic diaphragm pumps are manufactured in cast iron, aluminium and stainless steel for applications that require durability and tensile strengths.
Non-metallic options include Polypropylene and conductive Polypropylene for high corrosion resistance – especially useful in caustic services in the chemical industry.
These versatile electric diaphragm pumps – which incorporate features that have previously not been available in a single pump solution – are engineered to deliver high performance and serviceability, enabling users to achieve high efficiency, extended service life and the best cost of ownership.
“The new EVO series integrates key benefits of ARO air operated pumps, incorporating important features from other pump technologies, to offer an efficient electric diaphragm pump with controllability,” says Joe Pinheiro, BMG’s national product manager, pumps. “Conventional electric pumps normally have a double diaphragm design with a direct drive electric motor, while new ARO EVO pumps have a specially-designed triple diaphragm, with an integrated variable drive, maintenance-free gearbox and control panel. The leak free design with a secondary containment system, prevents the escape of hazardous fluids and oils and is enhanced by automatic leak detection.
“Due to the high-resistant three chamber design, there is no need for a pulsation dampener. These pumps have a true deadhead when the downstream valve is closed, automatically preventing the pumps from spinning, while holding the pressure.”
EVO electrical diaphragm pumps can handle the most aggressive and corrosive fluids and are available from BMG in a choice of two sizes and five different materials of construction.
Size 1” pumps are equipped with a 2,2 kW gear motor and 3,0 kW VFD that provides versatility for small batch and dosing applications. Size 2” pumps are equipped with a 5,5 kW gear motor and 7,5 kW VFD for large fluid transferring applications.
Other important features of EVO electrically operated diaphragm pumps are easy installation and maintenance – even in confined spaces and because this is a single pump system, there is no need for users to purchase accessories. This system, with built in control and monitoring capabilities, is IOT ready and offers full integration through PLC or HMI devices.
These electric diaphragm pumps, which conform to stringent international quality and safety specifications, are also supplied with hazardous duty certifications for hazardous environments. Apart from applications in the chemical and petrochemical sectors, these pumps are designed for use in processing, mining, wastewater treatment, manufacturing and general industry.
Also in BMG’s ARO range are the PRO series air-operated diaphragm pumps, designed to efficiently pump any type of liquid – from clean, light to medium viscosity fluids, to highly corrosive and abrasive fluids. ARO pumps can also transfer large particles without damaging the pump.
Notable features include a seal-less, self-priming design, with low material shear and minimal maintenance requirements. These portable pumps are easy-to-install and can run dry without damage. Most ARO diaphragm pumps are ATEX certified (CE Ex11 2GD X) enabling safe use in potentially explosive areas. This feature makes the ARO pumps ideal for underground applications, such as dewatering.
