Materials Handling Improving energy efficiency up to 80%
The Husky™ e-Series range combines all the benefits of a traditional air operated diaphragm pump (self-priming, stalling under pressure, a seal-less design and increased diaphragm life) with the benefits of an electric pump (energy cost savings, reduced pulsation and increased pump control).
with new Husky e-Series The 2 inch electric double diaphragm pump is now here!
These pumps are ideal for applications that require low pulsation and a smooth flow. The patented air charged drive allows for the elimination or reduction of pulsation without expensive pulsation dampeners or surge tanks.
New to the family: Husky 2150e The Husky electric range now has a new family member. Besides the Husky 1050e electric double diaphragm pump (1 inch), there now is a Husky 2150e. The Husky 2150e has a 2 inch (50.8 mm) connection and is available in aluminium, polypropylene and stainless steel. The pump is designed to transfer up to 530 l/ min and capable of moving solids up to 6.3 mm.
Why should you consider this pump? n A major part of the industry still works with air operated pumps. If you belong to this group, you will know that generating air is costly. The Husky 2150e has an electric drive and is therefore up to 5 times more efficient than any air driven pump on the market.
n The electric drive also makes that the pump can work where air is not available.
n Compared to other technologies, the Husky 2150e will lower your maintenance costs. Why? The technology enables the electric pump to stall under pressure when a line is closed and pressure gets too high, without additional switches and controls.
n Thanks to the electric drive’s low pulsation, shear sensitive liquids can be transferred using this pump.
Electric pumps in the field For the construction of a new inland tanker that transports chemicals to large water purification plants, a Dutch shipping company was looking for a solution that would save as much space as possible on board. The chemicals are added gradually to the cleaning process of the water purification and are intended to deal with the unpleasant odour.
Previously, a compressed air pump by a rival brand was used to fill the hose system. Space for a compressor had to be made in the ship’s engine room. Given that there is not much room on such a ship to begin with, this was a recurring problem. Moreover, air supply pipework from the compressor to the diaphragm pump had to be installed on board.
Space-saving Looking for an innovative solution, the shipping company approached a local Graco distributor. They proposed to install two Graco Husky electric pumps. Each unit has its own compressor discretely situated within the frame, saving space. Why two pumps? Using two pumps ensures the continuity of the process against any obstacles; as a result, the system can be filled up faster than before. The major advantage is that the shipping company no longer has to install a compressor in the engine room and therefore has more room for other things.
Quick and efficient In a subsequent phase, the distributor gave a demo with a test pump in order to show how the pump works and to give confidence to the shipping company that the system would work using the Husky. The demo proved that the pumps offer a

better total solution, and so it was an easy decision for the shipping company to opt for this innovative solution.
The two pumps were mounted on the deck midships. In total, the pumps have to fill a suction hose of around one hundred metres before the fluid, which is at a depth of four metres, reaches the pumps. In three minutes, the system was primed full of chemicals with a higher density than before. During commissioning of the system the optimum flow rates were obtained at 60% of the pumps’ capacity. This optimisation meant that the energy consumption was reduced considerably.
With these two electric pumps, the shipping company saved space in the ship’s engine room. The pumps ensure that the hose system is filled before the crew begins the actual unloading. The crew could thus prepare the process even before arrival, and begin to unload immediately after the ship had reached the port.
The shipping company is very satisfied with this solution and has ordered two more Husky pumps for another set-up.
“The most important thing we learned from this job is that the Husky has an enormous operational capability. The pump has an almost inexhaustible suction lift at the right rotational speed and is capable of circulating the specified chemicals,” says the Pump Specialist at the Dutch shipping company.
