The 11 benefits of an electric diaphragm pump

Would you like to eliminate unnecessary pump failures? Do you want to create a quieter and cleaner work environment? Look no further. Graco’s Husky electric double diaphragm pump (EODD) is the most energy-efficient and technologically advanced electric diaphragm pump on the market. Take a look at its exclusive features.

1. Stalls under pressure [UNIQUE]
One of the key advantages of the Husky EODD pump is that it is the only electric double diaphragm pump on the market that stalls under pressure. This eliminates the risk of damaging the pump or pipeline when it is blocked or a valve is closed.

2. Low pulsation mode [UNIQUE]
For applications that require low pulsation and a smooth flow, consider the Husky EODD technology. The patented drive allows for the elimination or reduction of pulsation without expensive dampeners or surge tanks.

3. No expensive equipment
There is no need to install additional deadhead protection equipment such as recirculation lines, pressure sensors, or motor management controllers.

4. Energy-efficient
Powered by a patented energy-efficient electric drive, the Husky EODD pumps hardly consume any air. Only a limited amount of air is used to pressurize the inner chamber, and this air remains within the pump.

5. Flow control and batch dispense
The Graco EODD Motor Control offers two control methods. Flow Control allows the pump to control its flow by increasing or decreasing the speed of the motor. The controller can be set to a specific desired flow rate, including maximum acceleration and deceleration. In Batch Dispense Mode, the pump dispenses a user-specified amount of material. The dispense flow rate and other characteristics can be specified by the user.

6. Self-priming
The Husky EODD is self-priming and has excellent suction capabilities. There is no need to install additional equipment to guarantee constant flow.

7. Dry running
Because of its unique diaphragm lock system, the Husky EODD can run dry indefinitely without any damage to its inner mechanism or its diaphragms. When the fluid supply is interrupted and the pump runs dry, the pressure difference between the air and fluid sides of the membranes causes them to decouple from the drive and remain stationary, while the drive keeps turning.

8. Sealless design
The Husky EODD has no sensitive mechanical seals, which significantly improves its life expectancy. Seals used in other pumps are often difficult and expensive to replace.

9. Low maintenance costs
No sensitive parts are used to manufacture the Husky EODD pump, and its diaphragms last up to five times longer than traditional pump components.

10. Wide operating range
The Husky EODD can be configured for any application and it can easily handle slurries, abrasives, shear-sensitive materials, and a wide variety of chemical substances.

11. Quiet operation
The Husky EODD does not require a muffler to dampen the noise caused by the air emitted by an air motor, so it runs much more quietly than AODD pumps.
