CDR Pumps explains to MEPCA how its electric double diaphragm pump can pay for itself in under six months, when used in place of a more traditional air-operated double diaphragm pump. 

A couple of years ago CDR Pumps introduced an electric diaphragm pump to its line-up. Known as an EODD, the pump gives the features and benefits of a traditional diaphragm pump (self-priming, solids handling, ability to stall, safe pumping of toxic chemicals) but with an electric motor drive, as opposed to expensive compressed air and, while it is an increasingly popular option for many manufacturing companies, many still haven’t come across this solution.

The ideal pump solution for applications that require low pulsation and a smooth flow, the EODD features a patented air-charged drive which reduces pulsation without the need for pulsation dampeners or surge tanks. At the same time, state-of-the-art technology allows the pump to stall under pressure preventing pump failures. To help improve all-important reliability, its seal-less diaphragm pump design eliminates leaking and failures. However, one of the major advantages offered by the pump is how its energy-efficient electric drive reduces energy consumption by up to five times compared to traditional air-operated diaphragm pumps. In typical use, this could equate to a saving in excess of £8,500 a year.

One of the biggest barriers when introducing the Electronically Operated Diaphragm pump to users is the cost. The pump is priced at two to three times the cost of an air-operated counterpart, and when potential users are running a tight budget, to a strict deadline, the figure on a quote is often the major deciding factor. However, an upfront cost that is around £2855 more can lead to a saving in running costs of around £4000 in just six months. This saving is largely thanks to a design that requires no compressed air (except for start-up, where if needed an inbuilt compressor can be fitted), no pulsation dampeners and no surge tanks.

So how is that saving made? A 1″ polypropylene air-operated diaphragm (AODD) will cost somewhere in the region of £800-£1000. A 1″ polypropylene electronically operated diaphragm pump will cost around £3800. However, while running the AODD using 65 cfm of compressed air per hour uses 16.25 kW of energy, running the EODD uses 1.5 kW of energy per hour (a small amount of air is required)

Based on an average energy usage cost of £0.10 per kK/hr of energy, the cost saving is £1.48 per hour. If these pumps are both run 24 hours a day for around 48 weeks a year, users will be paying £8524 less in energy usage costs by switching to the electronic pump every single year.

As well as reducing energy consumption and operation costs, the electric drive system increases pump control and enables fluids to be accurately metered. While the air-charged drive increases diaphragm life without compromising the fluid and there’s no hydraulic charge which reduces pulsation on the fluid outlet.
