Husky Electric Operated Double Diaphragm Pumps
Versatility meets efficiency
Professionals across all industries have been looking for ways to reduce pump failures and expensive maintenance, while improving overall performance at the same time. Graco’s unique Husky electric diaphragm pumps are the most energy-efficient and technologically advanced double diaphragm pump series on the market.
Versatile
Husky EODD pumps are designed to operate in the harshest working environments. They handle a wide variety of fluids such as slurries, abrasives, corrosives, and shear-sensitive materials. With pressures ranging from 1 to 7 bar and flow rates up to 830 liters per minute, they can be used for a wide range of applications in industries such as oil and gas, chemical, food and nutrition, water and wastewater, pharma etc.
Electric
The Husky EODD pump combines all the benefits of a traditional air operated diaphragm pump with the efficiency of an electric drive. This way, energy consumption is reduced up to 5x compared to AODD pumps. Husky pumps are built to last, with the best materials and according to our highest quality standards. Operation costs and maintenance are brought to a minimum, making the Husky EODD a powerful cost-effective and energy-efficient solution.
Efficient
The Husky EODD pumps are the only EODD pumps that stall under pressure without additional switches and controls. This unique feature prevents pump failures due to clogged lines or closed valves. It can operate at low pulsation, unlike other electric pumps, eliminating the need to install expensive pulsation dampeners or surge tanks. Furthermore, the Husky EODD’s seal-less design prevents leaking and failures due to run-dry pump conditions.
ENERGY EFFICIENT AND BUILT TO LAST
ADVANTAGES OF THE HUSKY ELECTRIC DIAPHRAGM PUMPS
Durable Pump Technology
Slurries, abrasives, corrosives etc.Thanks to their durable technology, Husky EODD pumps can handle a wide variety of fluids, all without damaging the pump. They are also gentle on shear-sensitive materials.
Double Diaphragm Features
- No rotating or moving fluid seals
Husky EODD pumps have no rotating or moving fluid seals. As mechanical seals are very expensive wear parts, the Husky EODD saves you money and downtime, because it eliminates the need for rotating or moving fluid seals. This is a major advantage when pumping abrasives or other fluids that are not supposed to leak through the rotating pump seals. The Husky EODD seals off the fluid completely from the environment. Fluids can no longer be spilled into the environment, even when the membranes fail. - Dry running
Husky EODD pumps can run dry, unlike some other pump technologies, as the moving membranes are not in contact with other pump parts. Lobe pumps, gear pumps, progressive cavity pumps, etc. have rotating components in contact with the other pump parts, which requires the fluid to level out the friction between these parts. Without fluid, friction rises and causes damage to the rotors and stators. - Self priming
Husky EODD pumps are self-priming. There is no need to fill the suction line prior to starting the pump. Husky EODD pumps can be placed below as well as above fluid level.
Electric Drive
Thanks to their electric drive, Husky EODD pumps reduce energy consumption up to 5x compared to air operated diaphragm pumps. The electric drive also increases pump control and allows you to accurately meter fluid.
Motor Options
Husky EODD pumps operate on 240v or 460v and are available with AC and brushless DC motors. As there is no pneumatic exhaust, they can also be used in hazardous locations as fluid spillage through the pneumatic exhaust, due to membrane failure, is not possible. The pump completely seals off the fluid from the environment
Air Charged Drive
Husky EODD pumps reduce pulsation on the fluid outlet, without expensive pulsation dampeners or surge tanks. They also stall under pressure without additional switches and controls – a unique feature for EODD pumps.
Fluid Section
The fluid section of Husky EODD pumps can be fully customized to your needs. Choose from multiple materials to configure manifolds, seats, balls, and diaphragms and create the pump you need.
How it works
Electric drive instead of compressed air
The main difference from an air operated diaphragm pump is the center section of the pump, as it uses an electric drive instead of compressed air. The center section of the pump is filled with pressurized air and is mechanically moved by the motor, so it pushes and pulls the diaphragm from left to right. This back-and-forth motion forces liquid out of the fluid chamber and into the outlet manifold, while filling the opposite fluid chamber via the inlet manifold. Husky EODD pumps do not consume air; they only use air to charge the center.
