Variable Speed Drive
Variable speed drive pumps are also known as "Constant Pressure" pumps as the speed of the motor is increased or decreased in response to demand. The more taps that are being used, the faster the motor revs and thus the water flow increases, this in turn keeps the pressure constant and steady, when the taps are turned off, the motor revs reduce and this also keeps the pressure constant. This is the perfect pump for modern homes with multiple showers where constant pressure is required. Suitable for small motels, hotels, large homes and many other applications where an efficient, reliable and economical constant pressure pumping unit is required.
