Mèta – a truly revolutionary pump A variable speed, multi-stage, self-priming pump with incorporated electronics – this is a very brief description of Mèta, the new pump from the e-idos line that Calpeda has recently introduced to the market. Even though it looks the same as the other pumps made by Calpeda, it is different. Important changes are usually associated with changes in shape, but in this case the revolution is all about substance. Actually, the true challenge with the new pump range was inserting technological innovation into the characteristic design of Calpeda pumps. “So, if you look at the new Mèta model and think it’s a traditional product, then that means we made the right choice,” says Graham Fay, Calpeda Ireland. “We have made sure that the compactness and various size options of the new pump, with its on-board variable speed control, have remained the same as other Calpeda pumps so that it fits perfectly into traditional installations.” Mèta eco-friendly heart When is an innovation truly an innovation? When it is accessible on a large scale and, as a result, can bring a real advantage and deliver a positive environmental impact. “This is the true revolution of Mèta,” continues Fay. “Designed as a very high-efficiency pump, Mèta has an eco-friendly heart that can make the difference in the commercial and domestic pump sector for water supplies and irrigation.

“The saving in energy usage with this new product – approximately 550kWh per year when used an average of four hours per day – can be seen immediately. Nor is the advantage merely economic. If this value is converted into amounts of CO2 not released into the atmosphere, the total comes to approximately 400kg per year. Being a variable speed pump, Mèta can control the speed of the pump according to the water demand. This alone makes it a solution centred on saving energy. But its performance is much higher than average and its footprint is decidedly ecological.” What makes Mèta so special? Extremely energy efficient, Mèta is a perfect example of the EU’s Ecodesign and Extended Product Approach initiatives.
It fully observes the new regulations whereby the product is assessed and judged in its entirety (pump, motor and controller). It can be described as a product with top-grade integration, characterised by the electronics in the motor casing and the control algorithms that make it very efficient. The result? 60% less energy consumption than an already-efficient pump. Savings in raw materials The consumption of raw materials, which is continually increasing, is a very important aspect for the environment. To produce the new Mèta, Calpeda says there was a base material saving (iron, copper and aluminium) of 45% when compared with a traditional pump. In addition, the optimised motor and controls mean that a physically smaller unit can be used while maintaining the same levels of performance. Finally, operation at a low temperature helps the motor and the bearings last a good deal longer. Contact: Graham Fay, Calpeda Ireland. T: 086 - 819 3059; E: graham@calpedaireland.com Q
