Wilo NLB Compact Horizontal End Suction Centrifugal Baseplate Pump Base Mounted End Suction Pumps

Introduction to Wilo-NLB Water Pump

• Product Overview: The Wilo-NLB is a flange-connected, compact horizontal end-suction centrifugal pump, suitable for liquid pumping in various scenarios. It features a compact structure, stable operation, and diverse materials, meeting different requirements. It is delivered as a complete pump with installation and operation & maintenance instructions.

• Advantages and Features

  • Compact Structure: The motor is rigidly connected to the pump shaft, eliminating the need for shaft alignment debugging.

  • Good Operation: Low noise, small vibration, high stability, and it can reduce operating costs.

  • Optional Materials: Components such as the pump body and impeller can be made of different materials to adapt to various environments.

• Structure Type: Flange-connected, compact horizontal end-suction centrifugal pump, with a direct-coupling structure, including a motor and a base, mechanical seal. Its size and performance comply with the DIN EN 733 standard. The flange pressure rating is PN 16 (PN25 is optional). It features an integrated design with a rigid coupling, and the motor is equipped with a thrust bearing to offset the axial force of the impeller.

• Application Range

  • Pumping clean or slightly polluted water (up to 20ppm) for circulation, delivery, and pressure-boosting water supply.

  • Pumping hot water, water - glycol mixtures, cooling water/chilled water, and industrial water that meet the VDI 2035 standard.

  • Applied in municipal water supply, irrigation, buildings, general industries, power stations, and other fields.
