Graco’s Husky 1050e electric double diaphragm pump is the only electric diaphragm pump on the market that will stall under pressure to prevent pump failures from clogged lines or closed valves, says Graco.
This can help to avoid the risk of damaging the pump or pipeline when blocked or a valve is closed.
It also improves control of metering and batching and eliminates risk of contamination of products due to the absence of hydraulic backing.
Its seal-less diaphragm pump design can also help to eliminate leaking rotational seals and failures due to run-dry pump conditions.
It works like a conventional air-operated double diaphragm pump (AODD), but its energy efficient electric drive is designed to reduce energy consumption by up to five times more than traditional air operated diaphragm pumps. The air required for running the 1050e is just 0.6 liters per day compared with 700 liters per minutes for many conventional units, the company says.
Other advantages include the lack of exhaust air, the ability to handle abrasives, and its quietness, making it suitable for applications in close proximity to staff.
The 1050e is best suited to applications that require low pulsation and a smooth flow. Its patented air charged drive allows for the elimination or reduction of pulsation without expensive pulsation dampeners or surge tanks.
Although it is designed for a wide range of applications, the company says it is especially well suited to the waste water treatment industry – for applications such as the pumping of sludge and slurry – where it can replace large peristaltic pumps.
