What we do at Callaghan Pump is start off with the best drive on the market. These are the innovators, the people that really polished and perfected a drive for pumps-- Yaskawa. Yaskawa drives combined with Callaghan Pumps make the absolute best pump control system you can buy. First based upon my research and experience, Yaskawa is the best variable frequency drive on the market. I can buy anybody’s drive that I want, and I spent two days calling every drive manufacturer and I found that Yaskawa was the only one with reliable and accessible customer service. As a general practice they have ten or more people on duty in customer service at the factory all of whom are degreed engineers who can help with questions.
Smart drives are advantageous over what we term dumb drives. Use of Yaskawa variable frequency drives allows for simpler installation and maintenance and prolongs the life of a pump. Additionally, the Yaskawa technical support provides excellent service in the event that your crew experiences questions running the drive.
With respect to the actual pumps, we can pair the Yaskawa drives with anyone’s pump as long as it is lead free. This includes all iron pumps and all stainless pumps. You can buy bronze impellers without lead. They are expensive when you compare them to a stainless steel pump or an all iron pump. All iron is absolutely fine provided the pump runs at least once a week. You do not want to let an all iron pump sit for six months without spinning it. On any average building in NYC, the pumps run multiple times a day. However, if you buy a spare pump and put it in storage, fill it with vegetable oil and spin it by hand at least once a month. No matter what pump you select you need to pair it with a Yaskawa smart drive for the most effective pump control system.
