When it comes to domestic water pump systems or domestic water tank or domestic water tank filled systems of any kind in New York City or anywhere else, you are best off keeping your system as simple as possible. Variable speed drive pumping is the absolute best method you can use, because it allows you to buy a system that has the least amount of parts- less parts means less things that break, the “keep it simple stupid” method
At Callaghan Pump and Controls, we believe in keeping your pumping systems simple. Open up any of our control panels and you will see this simplicity in action. A Callaghan variable speed drive pump system has four basic components: a disconnect switch through the door which is interlocked, two current breakers- one for each drive, two Yaskawa variable speed drives, two 4-20 transducers– That’s it folks. Simple! How am are we able to achieve this ease of operation — the Yaskawa Smart Drive. Yaskawa Smart Drives keep operation and maintenance of the system simple. Variable speed pumping in New York City is not easy when you have service calls, so why would you add additional equipment that fails? If you look at most systems on the market, they use programmable logic controllers, PLCs. Nobody knows who programs them. The guy that does the programming this year almost certainly won’t be there next year. It might be Joe this year, Bob next year or who knows. In contrast, consistency and accessibility to technical support are key attributes to the desirability of the Yaskawa Smart Drive. The Yaskawa Smart Drive has the same program in it now that it had ten years ago and they have 20 engineers available for technical support. If you ever have an issue, you call the Yaskawa IQ 1000 Technical Support HotLine and you can access technical support five days a week direct from the factory where over 20 people are in technical support, all of whom are degreed engineers. Not only are they able to answer questions but they are also able to access a working model of the drive you are calling about in a room where they have situated all of the various drives the company has produced over the years. So when you call, the technical support engineers are able to unclick their headsets and go to this room to assist you with the issues you are having with your specific drive by looking at the drive at their site. They can walk you through any technical issue you might have.
If you are pumping water in New York City, you should absolutely use the Yaskawa Variable Speed Drive(VSD). Yaskawa is the best and they eliminate the need for a power supply, they eliminate the need for a PLC, All you need is a disconnect switch, circuit breaker, drive and transducer. The rest is pumps and piping. Remember to keep it simple.
