‘KALSI’ brand Three-Phase Electric Monoblock Centrifugal Pumpsets are ISI marked as per IS : 9079 having motor conforming to IS : 7538. These are single suction pumps designed and built on a complete unit on one shaft, thereby eliminating separate shaft and pump body making the unit more compact. Kalsi Centrifugal Monoblock Pumpsets are also manufactured of Super Power (high head & high speed) of 3000 RPM with insulation class ‘A’ and ‘B’.

Classifications
a. Kalsi Centrifugal Monoblock pumpsets of 1500 RPM, insulation class ‘A’
b. Kalsi High Head & High Speed Super Power Monoblock Pumpsets of 3000 RPM, insulation class ‘A’ c. Kalsi High Head & High Speed Centrifugal Monoblock Pumpsets of 3000 RPM, insulation class ‘B’
