CHOOSING THE RIGHT PUMP: ELECTRIC DIAPHRAGM PUMPS VS OTHER PUMP TECHNOLOGIES

The benefits of the Husky Electric Double Diaphragm (EODD) pump compared to other technologies.

As Husky diaphragm pumps electric double (EODD) from Graco offer innovative and unique solutions to age-old problems encountered by companies using other pump technologies. Through its flexibility and customizable design, it is perfectly suited for an exceptional range of applications and conditions.

MAIN DISADVANTAGES OF TRADITIONAL PUMP TECHNOLOGIES

Here are some of the most common obstacles users face when working with traditional pump technologies.

Centrifugal pumps

Centrifugal pumps are reasonably priced but incompatible with many fluids. Its intricate and sensitive design is not suitable for abrasives and solids, which will quickly damage impellers. Because they work at high speed, they tend to shear liquids, so they are also not suitable for shear-sensitive liquids. Also, its design does not allow for much variation in flow rate. The application, pressure and flow rate need to be very stable for the pump to be efficient.

Magnetic Drive Pumps

While magnetic drive pumps have eliminated the problems caused by leaking mechanical seals, they can only be used with clean liquids, which makes them unsuitable for applications involving solids. In addition, its magnetic mechanism can cause overheating and even change the composition of the fluid. The heat generated by the magnets can be high enough to bake the process liquid constituents into the impeller magnet hub, resulting in a deposit buildup.

Rotary lobe pumps

Rotary lobe pumps require timing gears, which are located in the gearbox. This prevents the lobes from coming into contact, which is a great feature of this design. However, gears are an additional piece of equipment that needs to be maintained and replaced from time to time. They also do not perform when pumping thin, low-viscosity fluids as there are larger gaps between the lobes. Low viscosity fluid makes its way between the lobes, reducing lift and efficiency.

gear pumps

Gear pumps can pump fluids with high viscosity within an impressive temperature range, but are affected by high maintenance costs due to their sensitive design and the need for expensive spare parts. Due to their size, gear pumps are unsuitable for operations with large mass flow rates. They have a clearly defined design envelope outside of which they will have reduced lifespan and ineffective performance.

Progressive Cavity Pumps

Dry running is by far the main reason these pumps fail. Fluid must always be pumped to lubricate the contact surfaces between the rotor and stator. The progressive cavity pump drive transmits its power to the inner bolt through the pump housing using a rotating shaft seal. A mechanical seal is an expensive wear part that is sensitive to increased heat, abrasives and non-lubricating liquids, increasing the risk of leakage over time. Furthermore, the mechanical seal raises sanitation issues and its repair is expensive. Finally, the pumped material can be changed by the rotation and friction of the shaft and seal, further heating the liquid.

Peristaltic pumps

While peristaltic pumps are widely used and reliable for a variety of applications, especially for lower flow rates, users tend to be frustrated by the pumps' significant footprint and high maintenance costs. The flexible hose used in peristaltic pumps tends to degrade over time, particularly when used with abrasives. Unless the unit is equipped with an expensive leak protection feature, hose rupture can cause leaks and lead to hazardous situations. Because of this, hoses need to be replaced frequently.

BOMBAS EODD GRACO HUSKY

A HUsky bomba is a Graco Electric Double Diaphragm Pump (EODD). Compared to traditional pumps, the Husky EODD pump offers much more flexibility and sustainability as well as unique innovative features. Take a look at the benefits:

  • Self-excavation

The Husky EODD pump is self-priming and has excellent suction capability.

  • no seal

The Husky EODD's sealless diaphragm pump design eliminates expensive rotational seals, saving money on replacement parts and reducing downtime.

  • Flow control and batch distribution

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

  • Pressure stoppages

Graco's Husky EODD pump is the only electric diaphragm pump on the market that stalls under pressure, without the need for additional pressure sensors and controllers, to prevent pump failure due to clogged lines or closed valves.

  • Runs dry

The Husky EODD pump can run dry indefinitely without causing any damage to the system, thus avoiding costly repairs.

  • Low operating costs

The energy-efficient electric drive of the Husky EODD pump reduces energy consumption by up to five times compared to other technologies. Also, it does not require a pulsation dampener due to its low pulsation mode.

  • silent 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 quieter than AODD pumps.

  • Wide operating range

The Husky EODD pump is suitable for a variety of flow rates, pressures and applications. It poses no risk to shear sensitive liquids and can easily handle abrasives and solids. Plus, it can be configured in a wide variety of materials to suit any application.

  • reduced dimensions

The Husky EODD pump is extremely compact, so it takes up minimal space on the work floor.
