Product Overview
Water treatment operations require reliable high-volume fluid movement to process utility liquids efficiently. The Lowara NSCS50-250/185 serves as a core hydraulic component, ensuring that multi-branch filtration and distribution grids maintain steady pressurization.
The unit demonstrates a maximum flow rate of 1500 L/Min alongside a maximum pressure head of approximately 66.9 m. Electrical power is supplied via an 18.5 kW motor operating on a 415v three-phase grid, drawing 32.7 Amps. Physical pipeline connections measure 65 mm for the inlet and 50 mm for the outlet.
Liquid acceleration is managed by a hydraulic layout structured to limit intake turbulence. Utilizing a closed impeller, the equipment addresses erratic cavitation and establishes a predictable circulation rhythm that supports parallel industrial arrays.
Designed to accommodate thermal environments from -25°C to +120°C, the essential wetted parts are formed from fabricated AISI 316 stainless steel. A reinforced mounting frame and commercial-grade mechanical seal shield the rotational bearings from external particulate and friction wear.
FEATURES
- Rigid stub shaft coupling limits rotational drive deflection during operational load changes
- Service-optimized casing extraction permits immediate internal access while preserving fixed structural pipelines
- Heavy-duty mechanical seal interface blocks process particulate from entering the electrical housing
- Pre-drilled foundational base footings enable vibration-free anchoring to facility concrete floors
- Optimized discharge expansion chamber manages internal fluid friction to promote mechanical efficiency
- Dynamically balanced rotating assembly lowers operational mechanical noise emissions within enclosed spaces
- Elastomer o-rings prevent micro-leaks across varying high-pressure atmospheric conditions

Which alloy construction standards and mechanical seal metallurgy protect this flanged end-suction centrifugal pump during operation?
Produced for demanding fluid environments, the NSCS50-250/185 relies on alloy construction of cast iron casing with stainless steel closed impellers paired with mechanical face seals to withstand liquid corrosion.
How does this flanged end-suction centrifugal pump operate regarding electrical motor power in kilowatts and supply voltage current?
Actuated from dedicated power supplies, the NSCS50-250-185 features an electric motor rated at 18.5 kW (25.0 HP) powered by 380–415 V, 50 Hz, three-phase with a rating of 32.70 A.
Under high-pressure facility demand, what maximum working pressure rating and fluid temperature are sustained by this flanged end-suction centrifugal pump?
Configured across industrial piping systems, the NSCS50 250 185 maintains a maximum working pressure rating of 16 bar (PN 16) across fluid operating temperatures from -25°C to +120°C.
Across elevated facility pipework, what peak dynamic head does this flanged end-suction centrifugal pump generate?
Generating through distribution piping lines, the NSCS50_250_185 develops a maximum dynamic elevation head of approximately 66.9 m to elevate water.
When discharging fluid into plumbing lines, what maximum flow volume and pipe diameter apply to this flanged end-suction centrifugal pump?
Piping through designated connection lines, the NSCS50-250/185 provides a peak fluid flow rate of approximately 1500 L/Min connecting via DN 65 suction and DN 50 discharge flanged ports.
