Installation & Maintenance Guidelines

• Keep suction piping short, straight, and sloped upward toward the pump — prevents air pockets and priming loss.
• Never run the pump dry — install a float switch or dry-run protection relay in the motor starter circuit.
• Install isolation valves on both suction and delivery sides for safe maintenance without draining the system.
• Support piping independently; never transmit pipe weight through pump flanges or motor casing.
• For suction lifts > 5 m, confirm priming arrangement and verify NPSHr with the manufacturer's pump curve.
• Install a pressure gauge (delivery) and vacuum gauge (suction) for commissioning and ongoing fault diagnosis.
• Use long-radius elbows where possible, especially on the suction line, to reduce turbulence and friction losses.
• Schedule annual inspection: foot valve/strainer, mechanical seal, impeller wear rings, and motor insulation/bearings.
• For apartments: fit automatic water-level controllers and time-delay relays to prevent rapid pump cycling and motor overheating.
• Minimise number of bends in suction piping; every elbow on the suction side directly reduces NPSHa and increases cavitation risk.
