LWE Vertical Pipeline Sewage Pump

Product Introduction

The WLE and LWE series vertical sewage pumps are mainly composed of a shaft, bearing bracket, pump cover, impeller, pump base, motor bracket, and motor. The pump is a vertical, single-stage, single suction volute pump. The impeller adopts a double-channel structure, allowing effective passage of fibrous material up to 5 times the pump diameter and solid particles with a diameter equal to 50% of the pump diameter.

Working Condition

Flow rate: 2~1500 m³/h
Head range: 3~45 m
Rated speed N: 970 ~ 2900 r/min
Medium temperature: -15°C~+60°C
Medium density: ≤ 1.3 x 103 kg per m³
Medium pH value: 2-12 (For acidic or alkaline
media, it is recommended to use a stainless steel pump system)
Maximum working pressure of the pump system in the medium: ≤0.6 megapascals (MPA)

Usage Scenario

  1. Safe and Reliable, Reduced Maintenance Costs: Rotor components subjected to balance verification and a rational bearing arrangement effectively balance the radial and axial. forces of the pump. This ensures the long-term stable operation of the unit, with minimal vibration and low noise.
  2.  Strong Overcurrent Capability: A smooth and spacious flow passage, coupled with a special impeller anti-blocking design, ensures the pump operates efficiently and remains unobstructed.
  3. Double Sealing, Double Protection: A dual mechanical seal configuration in series provides double protection, ensuring the motor’s safety and reliability.

Conditions of use

  1. The pump should operate fully immersed in water, with a submersion depth not less than 0.5 meters and not exceeding 40 meters.
  2.  The environmental water temperature should not exceed 40°C. The working medium. should be non-corrosive clear water with a sand content not exceeding 0.1%, and a pH value between 6.5 to 8.5.
  3. The power supply should be three-phase 50 Hertz, with a rated voltage of 380 volts. The supplied voltage must be maintained within the range of 342 to 420 volts.
  4. The pump should be used within the applicable range near the rated head.
