• Dimensions and Weight: For detailed pump dimensions and weights, including packing dimensions and weights for single-phase and three-phase models, See the official PDF for exact tabulated values.

Installation

• When operating under suction conditions, install a foot valve or check valve at the suction pipe to prevent air ingress and water falling down when the pump stops, which can cause overheating and breakdown.
• Support both the suction and delivery pipes to prevent the pump from bearing their weight.
