The MS-4-2-1.5-BL is a robust multistage centrifugal pump engineered for high-head, medium-flow clean water applications such as irrigation systems, pressure boosting, and reservoir transfer. With a maximum shut-off head of approximately 122 mca and flow capacity up to 104 m³/h, it delivers reliable performance across a wide operating range.
Features multiple impeller diameter trims (204–240 mm) for precise matching to duty points and power requirements. High efficiency near the best efficiency point (BEP), low NPSHr for suction-limited installations, and durable construction make it ideal for demanding agricultural and water supply use.
The typical curve shows head dropping from ~122 mca at shut-off to lower values at higher flows, with efficiency peaking mid-range, power increasing with flow, and NPSHr rising at high capacities.
Head vs Flow & Efficiency Curve
Shut-off ~122 mca, max flow ~104 m³/h. Multiple impeller trims (204–240 mm) adjust the curve shape. Efficiency peaks near BEP; NPSHr rises at higher flows.
Q: What is the maximum head and flow? A: Approximately 122 mca at shut-off and up to 104 m³/h at low head. Best performance between 30–100 m³/h.
Q: Can impeller trims be adjusted? A: Yes – trims from ~204 mm to 240 mm allow matching to specific power and duty requirements.
Q: Is it suitable for suction-limited applications? A: Yes – low NPSHr helps prevent cavitation, but always ensure available NPSH exceeds NPSHr + safety margin.
