Brief introduction

NSQ submersible centrifugal pumps feature a unique double-impeller structure, including a stirring impeller installed on the base, secondary to the main impeller. The stirring impeller will drive the precipitated sludge into a turbulent flow and then pump the fluid. It features a strong discharge capacity and it will not become easily blocked. As long as the working current remains within the rated current, the allowable solid particle content within the medium can reach 30 to 60%.

During operation, the driver and pump submerge into the water, with a maximum working depth ranging between 20-25m.

Application

NSQ series pumps are used in a variety of industries for heavy media processing, including marine dredging, mineral processing, wet sand suction, waste sludge suction, sand reclamation, barge loading and more. It is an ideal replacement for a traditional mud pump.

Drive type According to different operating conditions, we provide motor and hydraulic drives for customers to choose from.
  • Motor drive
    If using a motor drive, an oil tank seal protection will be used, with a mechanical seal installed inside in order to prevent high pressure water and impurities from entering the motor cavity.
  • Hydraulic drive
    The hydraulic drive features a worry free performance about water entering the motor, because it adapts to higher water pressures and a higher suction height, thus preventing water from entering the motor cavity. The hydraulic drive is also an ideal solution if the pump cannot be easily connected to an external power supply.
Features Suction port structure of the pump with stirring impeller
Vertical Submersible Centrifugal Pump
  • The stirring impeller on the top of the pump will come into direct contact with the depositional surface. It is capable of controlling the sand concentration in the conveyed media through a diving depth.
  • Due to the underwater operation of the pump and drive, the suction head is not limited, and features a highly efficient sand absorption and thorough dredging.
  • Impeller, stirring impeller and other main wet ends are manufactured with a highly wear resistant and corrosion resistant material.
    • Vertical Submersible Centrifugal Pump
  • Operation is simple, and the pump requires no auxiliary vacuum pump or stirring device.
  • The driver submerges into water, and requires no grounding for fixing devices, which saves installation costs.
  • Triple protection: oil chamber flooding detection and alarm, motor chamber flooding detection and alarm, motor overheating detection and alarm
