SISDOZ A.Ş. launches Graco Husky Series electric double-diaphragm pumps

Diaphragm pumps, which are actively used in many sectors, generally come in two separate types: pneumatic and electric. These efficient products, preferred in many divisions of industry, have a distinctive successful operating principle. Pneumatic diaphragm pumps are frequently preferred in applications with explosion and fire hazards due to their ex-proof characteristics. The ex-proof and ATEX characteristics of pneumatic pumps are particularly effective in such situations. Graco Husky electric diaphragm pumps combine all the advantages of a conventional air-driven diaphragm pump—such as self-priming, pressure hold at load, and extended diaphragm life—with the advantages of an electric pump, including energy cost savings, low pulsation, and superior pump control. Husky Electric Diaphragm Pump is equipped with advantages that will reduce your energy consumption and enable cost savings.

Advantages of Husky Electric Diaphragm Pumps

- A large portion of the industry still operates with pneumatic pumps. If you are in this group, as you know, air production is quite costly. Elektrikli Husky pumps are up to 5 times more efficient compared to pumps available on the market that operate with compressed air.

• Electric pumps can also operate in conditions where air is not available.
• Compared to other technologies, Electric Husky will reduce your maintenance costs. Why? Thanks to this technology, the electric pump has the ability to stop under pressure without requiring any additional buttons or controls when one of the lines closes and pressure increases. This feature does not exist in all other electric pumps and poses a major problem.
• Low vibration, one of the advantages brought by electric energy, allows shock-sensitive liquids to be transferred through this pump.

1. Durable Pump Technology

• The pump can be used for abrasive fluids without any damage. • Suitable for pulsation-sensitive materials.

2. Diaphragm Pump

• Operates dry. • Has no rotating or moving parts. • Self-priming.

3. Electric Operation

• Reduces energy consumption and operating costs. • Enhances pump control. • Ensures accurate measurement of the fluid.

4. Motor Options

• Operates on 120V, 240V, or 480V power. • AC or Brushless DC options are available. • Special ex-proof – ATEX-approved motor options are available for hazardous areas.

5. Patent-Pending Air Charging Motor

• Extends diaphragm life without compromising the fluid. • Maintains vibration at the lowest level at the fluid outlet. • Stops under pressure without requiring any additional buttons or controls.

6. Fluid Section

• Constructed from materials suitable for your application and chemical through our multiple manifold, seal, ball, and diaphragm options.

How Does an Electric Double Diaphragm Pump Work?

Since it operates on electric energy rather than compressed air, the part that distinguishes this pump type from pneumatic diaphragm pumps is the center section of the pump. The center section of the pump is filled with pressurized air and moved back and forth with the help of an electric motor to push the diaphragm left or right. This back-and-forth motion fills the opposing fluid reservoir through the inlet manifold while pushing the fluid out of one reservoir and into the outlet manifold. After the transition, the fluid section filled during the previous transfer is emptied into the outlet manifold and fills the opposing reservoir through the inlet manifold. This smooth transition reduces vibration at the outlet.

How Does an Electric Diaphragm Pump Stop Under Pressure?

It should be noted that the center section of electric diaphragm pumps has no fixed connection. If the pressure value outside the center section is higher than inside, the diaphragms will stop without moving under pressure. In this case, while the center section continues to move back and forth, the diaphragms will not operate until the external pressure value drops below the internal pressure value of the center section.

Why Should You Choose Graco Electric Double Diaphragm Pump?

• Can handle a wide variety of fluids thanks to many material options. • Can handle abrasive and corrosive materials. • Sensitive to shear-sensitive materials. • Can be run dry. • Can hold pressure at load; closing a valve or blocking a line is not a problem. • Self-priming (no need to prime the pump for operation). • No rotating or moving material seals.

Compared to Air-Driven Double Diaphragm Pump;

• Energy savings: By using electric drive, you can achieve up to 80% energy savings compared to an air-driven pump. • Less noise due to the use of an electric motor. • Low pulsation mode, so you don't need to purchase a pulsation damper. • Service life of the diaphragms is similar to that of an air-driven pump. Currently available only as 1" Husky 1050e and 2" Husky 2150e series, research and development work continues for Graco Husky electric and double diaphragm pumps.
