* As we are constantly endeavoring to improve the performance of our products, we reserve the right to make alterations   from time to time and as such our products may differ from that detailed in this publication.
* All pumps employ a prime mover motor suitable for 230 V, 50 Hz, A.C. supply of single phase or 415 V, 50 Hz, A.C.   supply of three phase.
* The performance curves & data are at rated power supply and only indicative.
* Direction of rotation, marked with an arrow on the casting of each pump, check before coupting with the prime mover.
